And with that, it's time to bid you farewell. We promised you the possibility of an upset at the start, and Ireland delivered magnificently. They have continued their proud record of World Cup giant-killings and more importantly, put themselves in a great position to qualify for the quarter-finals.
If that's whetted your appetite for Cricket World Cup upsets, join us again at 21:30 GMT tonight to see if Scotland can pull off a even bigger shock against co-hosts New Zealand. See you then!
"Ireland gave a superb bowling performance up until the last 15 overs. The West Indies seemed to have put a total on the board that would be enough but Ireland weren't phased, they walked out there as if they knew they were going to knock those runs off."
"Ed Joyce looked on a different planet, he was a joy to watch, I would love to have seen him bat to the end he was that good. Ireland should be very happy with the way they bowled and batted. They've got work to do with their bowling at the death but all teams have.
"I'd say this is a better victory than the one against England, that was a one-man show from Kevin O'Brien, this was a team effort, five or six people putting their hands up and delivering a world class performance.
"They can certainly look to get out of the group. Every other so called big team in the group will have watched this and be very nervous."

Nick Bruzon: Wow. That's a story to wake up to. Congratulations, Ireland ! Looks like Eoin Morgan has backed the wrong horse.
"From an outsider's point of view there is being cool and being a fractured team and the West Indies really do look a fractured team at the minute."

Ireland were brilliant, but where do West Indies go from here? They looked all at sea, their top-order talisman Chris Gayle appeared well short of his brilliant best, and their bowling, under the unconvincing captaincy of youngster Jason Holder, was remarkably toothless.
Their lacklustre body language hinted at deeper issues too, and they now face an uphill battle to qualify for the knockout stages - they will probably have to beat one of India, Pakistan or South Africa. On this evidence, that would be a considerable surprise.
Player reaction
Man of the match Paul Stirling: "It's great to get that first win, and hopefully we'll get two out of two in a week's time. I owed the lads about 90 runs after dropping Sammy, so it was nice to get a few. It was a good toss to win and insert West Indies, and luckily we were able to chase it down."
Ireland captain Niall O'Brien: "Sammy and Simmons played well but we thought 300 was around a par score. There's no reason why we can't qualify for the knockout stages."
How's stat?
Ireland's win in 45.5 overs is the sixth quickest of all successful ODI run-chases of 300 or more.
"I think West Indies thought they would get a lot more loose stuff early on. To be fair they didn't throw it away but by the time the middle order was skittled by Dockrell that was more down to good bowling than bad batting."
Post update
Well, what a remarkable victory. If you're awake at this early in Ireland, you've been richly rewarded with a superb performance by your team.
Ireland bowled very well for the first 25 overs of the match, with George Dockrell and Andy McBrine befuddling West Indies with canny spin. Darren Sammy and Lendl Simmons then threatened to take the game away from Ireland with an explosive partnership, and 305 looked a formidable total.
But Ireland were in control of the chase from ball one, with Paul Stirling and Ed Joyce batting with authority and plenty of panache, and they got home with plenty to spare.
"Before the game I'm happy to admit I thought Ireland would come up short. I thought West Indies couldn't possibly play as badly as they had in the warm-up games and they'd just be too strong, but from ball one Ireland were the better team.
"Ireland thoroughly deserved the victory."
IRELAND BEAT WEST INDIES BY FOUR WICKETS

They've done it! Just as he did in Bangalore four years ago, John Mooney hits the winning runs to set the seal on another famous victory for Ireland.
For the third World Cup in a row, Ireland have humbled one of the established nations. They chased down a huge total with total confidence and composure, and it feels like this victory could be the most significant of the lot.
They've given themselves a fighting chance of qualifying for the quarter-finals, and with the ICC set to reduce the number of teams at the next World Cup, they've sent a message that they belong at this level.
Ireland 301-6
Two more singles take Ireland within one shot of glory. John Mooney hit the winning runs against England in 2011 - he has the chance to do it again here...

Niall O'Brien wallops consecutive fours to put smiles back on the faces in the Irish dugout. Panic over!
WICKET
K O'Brien run out (Smith) 0 (Ireland 291-6)
This is painful viewing. The O'Brien brothers' partnership lasts all of two balls as Niall calls Kevin through for a tight second run and Dwayne Smith's accurate throw finds the burly batsman well short of sanctuary. Ireland are making a right Devon Loch of this...

Wilson c Gayle b Taylor 1 (Ireland 290-5)
They couldn't, could they? Ireland's rampaging juggernaut of a chase has slowed to a crawl, and the pressure tells as Wilson cracks one into the mitts of Chris Gayle at cover. Suddenly, 15 runs looks a rather long way away...
Ireland 289-4
This would be only the fifth time that a team has chased 300 or more to win a World Cup match - and the third time by Ireland. No bowling attack will underestimate this line-up now. Wilson and O'Brien pick up three singles from Kemar Roach's over.
Ireland 286-4 (N O'Brien 65, Wilson 0)
Gary Wilson is the new man for Ireland. Taylor keeps Ireland honest, just a single from that over. Ireland have only mustered three runs from the last two overs - they just need to keep their heads here.
WICKET
Balbirnie c Bravo b Taylor 9 (Ireland 285-4)
Now then, some finish-line jitters from Ireland? Andrew Balbirnie seizes on a short ball from Taylor, but he hasn't quite got all of it and it's comfortably pouched by Darren Bravo at deep mid-wicket. Not a hint of celebration from the West Indies - they evidently feel this match is done.
Ireland 285-3
Ireland must have felt this game was slipping away from them when Darren Sammy and Lendl Simmons were carting their bowlers to all parts, but they've pursued this chase with utter conviction. Can I be mischievous and ask you to imagine how England might have fared chasing down 305? Anyway, Andre Russell is handed the ball, and delays the inevitable with a tight over which yields just two singles.

Ireland 283-3 (target 305)
Andrew Balbirnie, with just 12 ODIs under his belt, is the new man. He'll be nervous, no matter the apparent simplicity of the situation. Taylor fritters away one of the 31 runs the Windies have to play with with an utterly brainless wide. And there go four more - Taylor overpitches and Balbirnie times him through the covers like a old pro. And it's no fluke - an attempted slow ball from Taylor gets the same treatment. Van Morrison playing on the tannoy, emerald-shirted fans in raptures - this is Ireland's day.

Ireland 269-2
Last time Ireland shocked the world, it was Kevin O'Brien who hogged the headlines, this time big brother Niall is muscling in on the glory. Holder puts one in the slot and O'Brien opens his shoulders and slams him to the long-off boundary - that brings up his fifty. And he goes again - shuffle to leg, plenty of bottom hand, ball flying to the rope. 36 needed from 66. West Indies are bruised, bowed, surely beaten.

Dropped catch
Ireland 255-2 (Joyce 79, O'Brien 49)

That might be West Indies' last chance. It falls to the young skipper Jason Holder - Niall O'Brien tries to hoick a good slower ball from Taylor and mistimes it, it goes miles in the air, Holder does all the hard work running round and then watches in agony as the ball clanks off his wrists and hits the turf. Disaster.
Will O'Brien make him pay? You bet. First he belts Taylor over mid-off for four, then he spanks him through extra-cover for another. Taylor is going at 11 an over! 50 needed from 72, Ireland on the brink of another brilliant World Cup giant-killing.
Ireland 243-2
67 needed for Ireland. Cap'n Holder is back - he's down to his last chips in this casino. Ireland hold all the aces, especially with the fielders in the circle now, and that allows O'Brien to back away to leg and loft a peachy inside-out drive over the covers for four. Ireland are doing this in style.
Powerplay
Ireland 238-2 (target 305)
Time for the batting powerplay, often a harbinger of doom for England - will it put the hex on Ireland? Jerome Taylor is handed the nut, and he momentarily staunches the flow of boundaries, but Ireland continue to run the singles hard - five from that over. The West Indies need a flash of inspiration from somewhere...

Ireland 233-2
Chris Gayle, a man with enough X Factor to lock down the Christmas number one spot for decades, is back into the attack. But Ed Joyce looks serene out in the middle and he finds the rope again with a handsome chip over extra-cover. Ireland in control, West Indies drifting like an abandoned pedalo...
"The West Indies have to go to their x factor bowler. I'm just looking at their line-up to see who that might be."
Ireland 224-2 (Joyce 70, N O'Brien 27)
Jason Holder is ringing the changes - the bustling Andre Russell is the latest bowler to be tried. He can't turn the tide though - he obligingly serves one up on Niall O'Brien's hips and the batsman flicks him to the square-leg boundary. Russell then strays with a wide, and how costly the extra ball proves - short again and O'Brien cracks him to the boundary at point! Surely it's Ireland's to lose from here...
Lendl Simmons, who incidentally is the nephew of Ireland coach Phil, is called on to deliver some medium-pacers. That will please Uncle Phil, much too short and O'Brien clobbers it past the sprawling Samuels at long on. And another boundary as Joyce pulls powerfully through backward square! Ireland's runs needed are down to single figures, and the upset is very much on!

Niall O'Brien is the new man. Big responsibility on Ed Joyce's shoulders. That partnership was worth 106, by the way.

Captain Holder is back into the attack. Can he find a wicket? He nearly does! A short ball gets Ed Joyce fending off his hips to fine leg, where Darren Bravo running round, can't cling on and the ball trickles over the rope for four. Hundred stand up for these two, and that could be a big moment in this match.
"Ireland are going to have to do something catastrophically wrong and the West Indies are going to have to pull a bit of magic out of the hat. If these two are batting in 15 overs, 100% Ireland will win the game."

"Paul Stirling does have cramp. It's not just the batting, he's fielded for 50 overs and bowled as well. He's not the slightest fellow on the pitch and it's just catching up with him a bit."
Ireland 162-1
Jerome Taylor makes a rather odd sight bowling in his sleeveless sweater, and he'll be sweating on this as Stirling fetches one from outside off and swings it to cow corner for four. Taylor then sends down a short ball with about as much venom as a pet gerbil and Stirling swats him disdainfully over mid-wicket for a mighty six. And it gets better for Ireland! Taylor strays leg-side and Stirling clips him to the rope, and with the bowler rattled, the last ball of the over is too short and gets the treatment, clobbered through square leg. Four consecutive boundaries, 18 off the over.
Ireland 144-1 (target 305)
How's Jason Holder's head? 22 years old, captaining his country on the global stage, and staring down the possibility of an ignominious upset. He turns to his predecessor Darren Sammy for some more military medium. No let-up in the Irish assault though. First Sammy overpitches and Joyce smacks him through the covers for four, then he drops too short and Joyce pulls him to the fence at mid-wicket. And he adds another boundary for good measure with a cute flick to third man. Ireland on the charge.

Ireland 119-1 (Stirling 58, Joyce 22)

Thanks Jamie. So I rejoin you with this match very evenly poised. Sammy round the wicket, and immediately he serves one up in the slot and Ed Joyce batters it back over his head for a towering six.

Ireland 106-1 off 20 overs (run-rate 5.30) (target 305)
Sensible batting from the Irishmen, content to work singles from Gayle. The Windies were 71-2 at this stage. Can Ireland maintain this remarkably composed start? Here's James to take you through the remainder of the match.
Ire 102-1
Getty ImagesCopyright: Getty Images
The rumour of Darren Sammy's absence with the ball must have been a hoax. He is not at express pace, and keeper Ramdin is up to the stumps, but the Windies will hope he can add to his 80 ODI wickets. The sound of Pharrell Williams drifts across the ground. Sammy is usually as "Happy" as any but he was easily worked for singles in his opening over.
"It's been a very impressive fifty from Paul Stirling. He's been put through the wringer - they've come at him with short-pitched bowling - but he seems an unflappable character."
Ireland 99-1 (Stirling 55, Joyce 15)
Stirling reaches a neatly compiled fifty from 49 balls and then Sussex left-hander Joyce backs away to launch Gayle to the square cover boundary. The runs continue in the warm afternoon sunshine, perfect conditions at the Saxton Oval.
Six
Ire 91-1
The assured Ed Joyce, who played in the 2007 World Cup for England, hooks Russell for a 62-metre six. Purposeful stuff from the Irishmen, and still big Kevin O'Brien, the fastest World Cup centurion, to come.
"I think the big loss for the West Indies is the spinner Sulieman Benn - with his added height, he could have been a real handful on this wicket."
Ire 83-1 (Stirling 46, Joyce 4)
Gayle rattles through his overs with that short run-up/amble-up, which is my excuse for any typos. Stirling maintains the momentum with a powerful cut behind square for another boundary.
Ire 76-1 (target 305)
Russell continues but the 24-year-old Stirling, who has five ODI centuries to his name, with a highest score of 177 against Canada, negates him with ease and moves into the 40s.
"It was a quicker one from Gayle, outside off stump, Porterfield's eyes lit up and he went for the flashy drive, but he got a little tickle on it and Denesh Ramdin took a very difficult catch."
Wicket
Porterfield c Ramdin b Gayle 23 (Ire 71-1)
Good catch from the keeper. A flashing drive from Porterfield at a wide one and neatly snaffled in the gauntlets at the stumps. A beaming smile from Gayle as he takes his 159th ODI wicket. Porterfield faced 43 balls and had a strike rate of 53.48, helped massively by his one six.
"When you're chasing a total like this, it's very easy to get carried away, but Ireland have batted sensibly - they've hit the bad balls and put West Indies under a bit of pressure but not too much."
Dropped catch
Ire 70-0 (run-rate 5.38)
The first chance. Russell spills a return catch offered by Porterfield. It was pushed firmly back by the left-hander and the muscular paceman sticks out his right hand, but it doesn't stay in. At this level etc etc.
Ire 66-0
Christopher Henry Gayle ambles to the crease in his dark glasses. Five paces for his off spinners. Umpire Oxenford asks for a replay as Porterfield is sent back but the batsman was virtually behind the stumps when the bails were removed. Still no maiden as a single is taken from the final ball.
"The West Indies are going for the short-ball theory, which is strange because all the scoring shots that the Irish batsmen have played to the short ball have gone for six. I think a better area to these lads is right around the top of off stump."
Ire 65-0 (11 overs)
Andre Russell, resplendent with sharp Mohawk haircut and beard combination, joins the attack and there is a slip in place but not much work for him. A slower ball bouncer to finish, but all too easy for the batsmen.
Stirling plays with a beautifully straight bat, doesn't hit it too hard, just uses the pace of Taylor and strokes it through the gap between extra cover for four. The Windies had stuttered to 40-2 after the compulsory 10 powerplay overs of their innings. Five fours and two sixes for the Irish already.
Ire 56-0 (run-rate 6.22)
A wide for both leg-side angle and perhaps also height from Holder as the Windies persist with the short-pitched approach, which has hardly been fruitful thus far. Marlon Samuels and Chris Gayle can provide some spin but if Sammy is unable to bowl as is feared, the options are a little alarming.

Six
Ire 54-0 (Porterfield 18, Stirling 27)
APCopyright: AP
The smaller but powerfully built Jerome Taylor comes into the attack and surprises Stirling with a lifting short ball that evades his attempted pull and thuds into the side of his grille. A replacement helmet is called for and the bearded opener is fit to continue, clipping the next ball calmly for two more runs. Then when Taylor tests him with another bouncer he swats it without looking at the ball a la IT Botham at Old Trafford in 1981 for six over fine-leg. What a start.
"Jason Holder reminds me of the battery of West Indies fast bowlers in the 1970s. He's the same build - a very tall man with very long legs - and with the same action."
Ire 44-0 (target 305)
Holder has taken 62% of his wickets against the top order but that doesn't look likely to improve any time soon, four more byes adding to the total when a looping bouncer drifts down the leg-side and out of the reach of the diving wicketkeeper Ramdin. The 23-year-old skipper will surely be anxious, not only about his bowling, but by the start the Irish openers have made.
Ire 40-0
Getty ImagesCopyright: Getty Images
Four more to Porterfield as Roach is guilty of dropping short again. The paceman has gone for 26 from his opening three overs. This opening attack must rank as one of the most innocuous of recent years. Quite what Geoffrey would make of it I dread to think.
"Kemar Roach is just bowling a little bit too short. His captain will be a bit disappointed with his opening salvo. The Irish are going along nicely - they couldn't have asked for a better start."
Ire 32-0 (Porterfield 12, Stirling 16)
Better from captain Holder, beating Porterfield with some movement away from the left-hander. A single deprives him of the first maiden, and despite that sketchy start there were only two in the West Indies innings. At the same stage, they were 21-0.

Ire 31-0 (target 305)
I must admit I thought there might have been some early wickets after that late barrage from the Windies but I should have know not to under-estimate the Irish. A beautiful punched drive down the ground brings Stirling another boundary. A watching Curtly Ambrose is stretching his long legs in a light blue West Indies leisure suit and I am convinced he would still present more threat than members of the present day attack.

CENTURY AND WICKET
WI 302-7
Getty ImagesCopyright: Getty Images
A second ODI century from Simmons, sealed with a boundary, and a highly accomplished 83-ball hundred. He departs from the penultimate ball of the innings, caught in the deep. Big Curtly Ambrose is amongst the West Indies backroom staff, applauding his man off.
"Sammy and Simmons pulled it back for the West Indies, and now they're going to set a very formidable total. They'll be looking at 310 or 315."
Six
WI 295-6 (run-rate 6.02)
That won't do much for Mooney's mood, high into the clear blue sky and over the ropes as Simmons moves into the 90s. Russell then chips one high on the bat that bisects two fielders.
"Bowling at the stumps at the death isn't fashionable any more, but I think more people should do it. When you bowl wide of the stumps, there's only one way you can be out - caught."
WI 280-6 (run-rate 5.83)
Burly Kevin O'Brien is straying a bit, offering Simmons too much width and the Trinidadian frees his arms for consecutive boundaries, Russell scything another for good measure and completing an expensive over with a majestic strike many a mile. Big Kev might have to make another century, but he's more than capable as England will attest.
"You normally look for about 10 an over in your last three overs. That would take West Indies up to 291, and they'd be absolutely over the moon with that, considering the position they were in when Dockrell was running through the middle order."
WI 261-6 (partnership 20)
Andre Russell has four ODI fifties to his name, with a best of 92, and as Mooney strays down the leg-side the Windies all-rounder collects a boundary. There is a review for lbw from Ireland but they are not confident and rightly so. The bearded Mooney, despite his injury, is still charging in and chasing everything however.
WI 254-6 (Simmons 79, Russell 2)
The recently retired Australia paceman Brett Lee has been working with the Irish bowlers and it is clear he has had an influence, but Sorensen then sends down a leg-side full toss that Simmons flicks nonchalantly over the ropes. A portly figure in the crowd attempts a spectacular diving catch and fails, but does succeed in flattening two unsuspecting ladies.
"It was a good catch from Dockrell - coming in from the boundary, low down around his ankles. It's been a good knock from Darren Sammy."

But next ball Sammy is caught at mid-wicket for a magnificent 89 from 67 balls, ending a partnership of 154. Mooney is still incensed however. Injured and irascible. But you've just dismissed Darren Sammy, John!
Dropped catch & Six
WI 241-5
A reprieve for Sammy as Sorensen pushes a big hit over the ropes. Mooney is an aggressive looking character at the best of times and his face was not a pleasant sight, contorted in rage. Sammy moves to 89 and now has his highest score in ODIs.
"They are really starting to roll now, these boys. They've consolidated when they needed to and now the West Indies can really push on."
Six
WI 228-5 (K O'Brien 1-52 from 8)

Fifty from 60 balls for Simmons, who then hoicks Kevin O'Brien for the seventh six of the innings. He had played second fiddle to Sammy for the majority of the partnership but his strike-rate for his last 10 balls is a whopping 250. Big over, 22 from it.
"If these two stay at the crease, 270 is certainly within the hunt. It's very important that the Irish hold themselves together here."
WI 206-5 (partnership 119)
Fabulous brute force from Sammy as he drives Stirling back over his head. The ball took barely a second from bowler's hand to crashing into the boundary board.
WI 198-5 (Simmons 44, Sammy 72)
Mooney's right leg is hoisted vertically by the ruthless Ireland physio at the boundary edge. Just the one boundary in the Kevin O'Brien over as Sammy lashes backward of square. The former skipper has a strike rate of 180 from his last 10 deliveries faced.

Pete Naylor: Sammy has been instrumental in getting the Simmons to rotate the strike and keep the scoreboard ticking. His wicket is vital.
Century stand
WI 190-5 (Simmons 42, Sammy 67)
It was always thought the great West Indies opener Gordon Greenidge became even more of a force when injured and Sammy is continuing the mantel, flicking the returning Mooney effortlessly off his pads for four more. The aggressive looking Irish paceman appears to land awkwardly in his delivery stride and he is also now struggling with an injury. The 100 partnership arrives from 104 balls.

Six
WI 180-5 (run-rate 4.50)
Bad back or not, Sammy is still able to launch and Simmons plays a masterful late cut for four more, the best over of the innings for the Windies with 12 from it. "All about the bass" booms out as a prostrate Sammy is prodded and pulled in painful looking fashion by the West Indies physio. It's all about the back. He has a sip of water and the treatment appears to be him attempting press ups and the physio holding him down.
"Both Simmons and Sammy have done exactly what's been required. They've given the West Indies a chance of getting to a decent score."

This Saxton Oval in Nelson is a remarkably beautiful ground, with rolling hills beyond in delightful shades of emerald green. I read that Mr Agnew thinks Adelaide is the prettiest in international cricket but this must rival it surely? Burly Kevin O'Brien continues and he is cut away behind square for four by Sammy who punches the air, one of the most demonstrative cricketers of recent vintage, and highly entertaining. He is stretching his back at the end of the over though, worryingly for the Windies.
"Darren Sammy is making George Dockrell bowl bad balls. By hitting him over cover in the last over, he's put him under pressure. He's a very wristy player, he doesn't move his feet much, just throws his hands through the line of the ball."
WI 163-5 (partnership 76)
Sammy is not one for the purist's coaching manual but he has phenomenally strong forearms and he whips Dockrell for successive boundaries into the leg-side, completing his half century from 45 balls with a single off the final ball of the over, slightly denting the left-arm spinner's figures, which are still a very respectable 3-50.

Glen Towler: I never thought I would see the day that the mighty West Indies would be doing so badly against Ireland.
David McQueen: Perhaps all of the Windies were injured in a freak group training accident that is preventing them from running...
Six
WI 152-5
A momentary frisson of excitement as the Windies scamper a tight single and Gary Wilson's shy at the stumps strikes the diving Darren Sammy in an, ahem, very vulnerable area. Then an extraordinary shot from Simmons as he eyes up a bouncer from O'Brien and uppercuts it powerfully to the point boundary for six. This is a very handy partnership for West Indies.
"The captain has got to get another twenty overs off the seamers, so he's just trying to mix and match, trying to sneak a few overs here and there. Sammy and Simmons are still capable of getting West Indies up to a decent score."
Powerplay
WI 144-5 (Simmons 26, Sammy 38)
The powerplay begins and the run-rate is exactly four per over now. Dockrell is launched over extra cover for four by Sammy, who has a highest ODI score of 84.

Padraig McKeon: Tracking Ireland on #bbccricket as I finish some work. Sounds like another 'well coached' Irish team taking game to supposed betters.
WI 137-5 (run-rate 3.91)
Ireland rattling through the overs and cranking up the pressure. Simmons, usually a fluent player, cannot get the persistent Stirling through the packed in-field but again the final ball of the over is a bad one and is cut to the boundary. "Footloose" comes over the public address, but the footwork was exemplary for that cut shot.
"Darren Sammy is one of those players, like MS Dhoni, who hits the ball so well, you really don't want to give him 10 overs at the end."
WI 129-5 (Simmons 17, Sammy 33)
Eight of this Ireland team played in the famous World Cup victory against England four years ago. Sorensen is one of the newcomers and he blots his copybook with a long hop final delivery which Sammy smashes ruthlessly to mid-wicket for four.
"You have to take your hat off to Andrew McBrine. Ten overs, 0-26, that's fantastic bowling. He's done a real job for his captain."
WI 123-5 (run-rate 3.73)
Metronomic McBrine continues, just 21, and three singles are all that he concedes. He has completed remarkable figures of 0-26 from his 10 overs against this collection of West Indian cavaliers.

"I'd say this is a better victory than the one against England, that was a one-man show from Kevin O'Brien, this was a team effort, five or six people putting their hands up and delivering a world class performance.

"From an outsider's point of view there is being cool and being a fractured team and the West Indies really do look a fractured team at the minute."
Post update
Ireland were brilliant, but where do West Indies go from here? They looked all at sea, their top-order talisman Chris Gayle appeared well short of his brilliant best, and their bowling, under the unconvincing captaincy of youngster Jason Holder, was remarkably toothless.
Their lacklustre body language hinted at deeper issues too, and they now face an uphill battle to qualify for the knockout stages - they will probably have to beat one of India, Pakistan or South Africa. On this evidence, that would be a considerable surprise.
Player reaction
Man of the match Paul Stirling: "It's great to get that first win, and hopefully we'll get two out of two in a week's time. I owed the lads about 90 runs after dropping Sammy, so it was nice to get a few. It was a good toss to win and insert West Indies, and luckily we were able to chase it down."
Ireland captain Niall O'Brien: "Sammy and Simmons played well but we thought 300 was around a par score. There's no reason why we can't qualify for the knockout stages."
How's stat?
Ireland's win in 45.5 overs is the sixth quickest of all successful ODI run-chases of 300 or more.

"I think West Indies thought they would get a lot more loose stuff early on. To be fair they didn't throw it away but by the time the middle order was skittled by Dockrell that was more down to good bowling than bad batting."
Post update
Well, what a remarkable victory. If you're awake at this early in Ireland, you've been richly rewarded with a superb performance by your team.
Ireland bowled very well for the first 25 overs of the match, with George Dockrell and Andy McBrine befuddling West Indies with canny spin. Darren Sammy and Lendl Simmons then threatened to take the game away from Ireland with an explosive partnership, and 305 looked a formidable total.
But Ireland were in control of the chase from ball one, with Paul Stirling and Ed Joyce batting with authority and plenty of panache, and they got home with plenty to spare.

"Before the game I'm happy to admit I thought Ireland would come up short. I thought West Indies couldn't possibly play as badly as they had in the warm-up games and they'd just be too strong, but from ball one Ireland were the better team.
"Ireland thoroughly deserved the victory."
IRELAND BEAT WEST INDIES BY FOUR WICKETS
They've done it! Just as he did in Bangalore four years ago, John Mooney hits the winning runs to set the seal on another famous victory for Ireland.
For the third World Cup in a row, Ireland have humbled one of the established nations. They chased down a huge total with total confidence and composure, and it feels like this victory could be the most significant of the lot.
They've given themselves a fighting chance of qualifying for the quarter-finals, and with the ICC set to reduce the number of teams at the next World Cup, they've sent a message that they belong at this level.
Ireland 301-6
Two more singles take Ireland within one shot of glory. John Mooney hit the winning runs against England in 2011 - he has the chance to do it again here...
Ireland 299-6
Niall O'Brien wallops consecutive fours to put smiles back on the faces in the Irish dugout. Panic over!
WICKET
K O'Brien run out (Smith) 0 (Ireland 291-6)
This is painful viewing. The O'Brien brothers' partnership lasts all of two balls as Niall calls Kevin through for a tight second run and Dwayne Smith's accurate throw finds the burly batsman well short of sanctuary. Ireland are making a right Devon Loch of this...
Ireland 290-5 (target 305)
Kevin O'Brien, the hero of that incredible win over England at the last World Cup, is the new man.
WICKET
Wilson c Gayle b Taylor 1 (Ireland 290-5)
They couldn't, could they? Ireland's rampaging juggernaut of a chase has slowed to a crawl, and the pressure tells as Wilson cracks one into the mitts of Chris Gayle at cover. Suddenly, 15 runs looks a rather long way away...
Ireland 289-4
This would be only the fifth time that a team has chased 300 or more to win a World Cup match - and the third time by Ireland. No bowling attack will underestimate this line-up now. Wilson and O'Brien pick up three singles from Kemar Roach's over.
Ireland 286-4 (N O'Brien 65, Wilson 0)
Gary Wilson is the new man for Ireland. Taylor keeps Ireland honest, just a single from that over. Ireland have only mustered three runs from the last two overs - they just need to keep their heads here.
WICKET
Balbirnie c Bravo b Taylor 9 (Ireland 285-4)
Now then, some finish-line jitters from Ireland? Andrew Balbirnie seizes on a short ball from Taylor, but he hasn't quite got all of it and it's comfortably pouched by Darren Bravo at deep mid-wicket. Not a hint of celebration from the West Indies - they evidently feel this match is done.
Ireland 285-3
Ireland must have felt this game was slipping away from them when Darren Sammy and Lendl Simmons were carting their bowlers to all parts, but they've pursued this chase with utter conviction. Can I be mischievous and ask you to imagine how England might have fared chasing down 305? Anyway, Andre Russell is handed the ball, and delays the inevitable with a tight over which yields just two singles.

Hugh in France: Why did the West Indies bother going? They don't look at all interested.
Ireland 283-3 (target 305)
Andrew Balbirnie, with just 12 ODIs under his belt, is the new man. He'll be nervous, no matter the apparent simplicity of the situation. Taylor fritters away one of the 31 runs the Windies have to play with with an utterly brainless wide. And there go four more - Taylor overpitches and Balbirnie times him through the covers like a old pro. And it's no fluke - an attempted slow ball from Taylor gets the same treatment. Van Morrison playing on the tannoy, emerald-shirted fans in raptures - this is Ireland's day.

Last time Ireland shocked the world, it was Kevin O'Brien who hogged the headlines, this time big brother Niall is muscling in on the glory. Holder puts one in the slot and O'Brien opens his shoulders and slams him to the long-off boundary - that brings up his fifty. And he goes again - shuffle to leg, plenty of bottom hand, ball flying to the rope. 36 needed from 66. West Indies are bruised, bowed, surely beaten.

Dropped catch
Ireland 255-2 (Joyce 79, O'Brien 49)
That might be West Indies' last chance. It falls to the young skipper Jason Holder - Niall O'Brien tries to hoick a good slower ball from Taylor and mistimes it, it goes miles in the air, Holder does all the hard work running round and then watches in agony as the ball clanks off his wrists and hits the turf. Disaster.
Will O'Brien make him pay? You bet. First he belts Taylor over mid-off for four, then he spanks him through extra-cover for another. Taylor is going at 11 an over! 50 needed from 72, Ireland on the brink of another brilliant World Cup giant-killing.
Ireland 243-2
67 needed for Ireland. Cap'n Holder is back - he's down to his last chips in this casino. Ireland hold all the aces, especially with the fielders in the circle now, and that allows O'Brien to back away to leg and loft a peachy inside-out drive over the covers for four. Ireland are doing this in style.
Powerplay
Ireland 238-2 (target 305)
Time for the batting powerplay, often a harbinger of doom for England - will it put the hex on Ireland?

Jason Holder is ringing the changes - the bustling Andre Russell is the latest bowler to be tried. He can't turn the tide though - he obligingly serves one up on Niall O'Brien's hips and the batsman flicks him to the square-leg boundary. Russell then strays with a wide, and how costly the extra ball proves - short again and O'Brien cracks him to the boundary at point! Surely it's Ireland's to lose from here...

Captain Holder is back into the attack. Can he find a wicket? He nearly does!

"Paul Stirling does have cramp. It's not just the batting, he's fielded for 50 overs and bowled as well. He's not the slightest fellow on the pitch and it's just catching up with him a bit."
Ireland 162-1
Jerome Taylor makes a rather odd sight bowling in his sleeveless sweater, and he'll be sweating on this as Stirling fetches one from outside off and swings it to cow corner for four. Taylor then sends down a short ball with about as much venom as a pet gerbil and Stirling swats him disdainfully over mid-wicket for a mighty six. And it gets better for Ireland! Taylor strays leg-side and Stirling clips him to the rope, and with the bowler rattled, the last ball of the over is too short and gets the treatment, clobbered through square leg. Four consecutive boundaries, 18 off the over.
Ireland 144-1 (target 305)
How's Jason Holder's head? 22 years old, captaining his country on the global stage, and staring down the possibility of an ignominious upset. He turns to his predecessor Darren Sammy for some more military medium. No let-up in the Irish assault though. First Sammy overpitches and Joyce smacks him through the covers for four, then he drops too short and Joyce pulls him to the fence at mid-wicket. And he adds another boundary for good measure with a cute flick to third man. Ireland on the charge.
Six
Ireland 131-1
Kemar Roach is recalled to the attack, and boy is Paul Stirling delighted to see him. His first ball disappears into the stands at long-on with a vicious swing of Stirling's meaty arms. Then Roach drops too short again and Stirling frees those arms once more, clattering a pull to the cow-corner boundary. 12 runs from another productive over by Ireland.
Ireland 119-1 (Stirling 58, Joyce 22)

Ire 106-1 (run-rate 5.30)
Sensible batting from the Irishmen, content to work singles from Gayle. The Windies were 71-2 at this stage. Can Ireland maintain this remarkably composed start? Here's James to take you through the remainder of the match.
Ire 102-1
The rumour of Darren Sammy's absence with the ball must have been a hoax. He is not at express pace, and keeper Ramdin is up to the stumps, but the Windies will hope he can add to his 80 ODI wickets. The sound of Pharrell Williams drifts across the ground. Sammy is usually as "Happy" as any but he was easily worked for singles in his opening over.

Good catch from the keeper. A flashing drive from Porterfield at a wide one and neatly snaffled in the gauntlets at the stumps. A beaming smile from Gayle as he takes his 159th ODI wicket. Porterfield faced 43 balls and had a strike rate of 53.48, helped massively by his one six.

"When you're chasing a total like this, it's very easy to get carried away, but Ireland have batted sensibly - they've hit the bad balls and put West Indies under a bit of pressure but not too much."
Dropped catch
Ire 70-0 (run-rate 5.38)
The first chance. Russell spills a return catch offered by Porterfield. It was pushed firmly back by the left-hander and the muscular paceman sticks out his right hand, but it doesn't stay in. At this level etc etc.
Ire 66-0
Christopher Henry Gayle ambles to the crease in his dark glasses. Five paces for his off spinners. Umpire Oxenford asks for a replay as Porterfield is sent back but the batsman was virtually behind the stumps when the bails were removed. Still no maiden as a single is taken from the final ball.

"The West Indies are going for the short-ball theory, which is strange because all the scoring shots that the Irish batsmen have played to the short ball have gone for six. I think a better area to these lads is right around the top of off stump."
Ire 65-0 (11 overs)
Andre Russell, resplendent with sharp Mohawk haircut and beard combination, joins the attack and there is a slip in place but not much work for him. A slower ball bouncer to finish, but all too easy for the batsmen.

Ire 61-0 (Taylor 0-15 from 2)
Stirling plays with a beautifully straight bat, doesn't hit it too hard, just uses the pace of Taylor and strokes it through the gap between extra cover for four. The Windies had stuttered to 40-2 after the compulsory 10 powerplay overs of their innings. Five fours and two sixes for the Irish already.
Ire 56-0 (run-rate 6.22)
A wide for both leg-side angle and perhaps also height from Holder as the Windies persist with the short-pitched approach, which has hardly been fruitful thus far. Marlon Samuels and Chris Gayle can provide some spin but if Sammy is unable to bowl as is feared, the options are a little alarming.

Cricinfo reporter Andrew McGlashan on Twitter in Nelson: Sammy unlikely to bowl in this innings. His medium pace could have been useful.
The West Indies all-rounder appeared to be struggling with a back injury during his innings.
Six
Ire 54-0 (Porterfield 18, Stirling 27)
The smaller but powerfully built Jerome Taylor comes into the attack and surprises Stirling with a lifting short ball that evades his attempted pull and thuds into the side of his grille. A replacement helmet is called for and the bearded opener is fit to continue, clipping the next ball calmly for two more runs. Then when Taylor tests him with another bouncer he swats it without looking at the ball a la IT Botham at Old Trafford in 1981 for six over fine-leg. What a start.

"Jason Holder reminds me of the battery of West Indies fast bowlers in the 1970s. He's the same build - a very tall man with very long legs - and with the same action."
Ire 44-0 (target 305)
Holder has taken 62% of his wickets against the top order but that doesn't look likely to improve any time soon, four more byes adding to the total when a looping bouncer drifts down the leg-side and out of the reach of the diving wicketkeeper Ramdin. The 23-year-old skipper will surely be anxious, not only about his bowling, but by the start the Irish openers have made.
Ire 40-0
Four more to Porterfield as Roach is guilty of dropping short again. The paceman has gone for 26 from his opening three overs. This opening attack must rank as one of the most innocuous of recent years. Quite what Geoffrey would make of it I dread to think.

"Kemar Roach is just bowling a little bit too short. His captain will be a bit disappointed with his opening salvo. The Irish are going along nicely - they couldn't have asked for a better start."
Ire 32-0 (Porterfield 12, Stirling 16)
Better from captain Holder, beating Porterfield with some movement away from the left-hander. A single deprives him of the first maiden, and despite that sketchy start there were only two in the West Indies innings. At the same stage, they were 21-0.
News from Australia's camp
Australia all-rounder James Faulkner will miss another World Cup match after being ruled out of the second group game against Bangladesh with injury.
The 24-year-old suffered a side strain in the lead-up to the tournament and missed Australia's opening win over England in Melbourne on Saturday.
"I've no chance for Bangladesh, I can tell you that," said Faulkner. "Time's sort of flown a bit, but hopefully I'm back sooner rather than later."
Ire 31-0 (target 305)
I must admit I thought there might have been some early wickets after that late barrage from the Windies but I should have know not to under-estimate the Irish. A beautiful punched drive down the ground brings Stirling another boundary. A watching Curtly Ambrose is stretching his long legs in a light blue West Indies leisure suit and I am convinced he would still present more threat than members of the present day attack.
Ire 21-0 (Porterfield 10, Stirling 6)
No alarms for the batsmen, Stirling cutting the first four of the innings, Holder unable to trouble either player.
Post update
Six
Ire 16-0 (run-rate 8.00)
Kemar Roach, in for the injured giant slow left-armer Sulieman Benn today, takes the other new ball, his thick gold chain gleaming in the afternoon sunshine. A stiffish breeze is blowing across the perfectly manicured chequered outfield. Hesitation amongst the batsmen but no disaster, and then Porterfield pulls a mighty six, holding the pose for the cameras. Hardly overawed the Irish are they?

Cricket statistician S Rajesh on Twitter: 218 runs scored by numbers 6-9 in the West Indies innings. Only once [in the World Cup] have No. 6 and lower batsmen scored more - India v Zimbabwe in 1983.
Ire 8-0 (target 305)
Not the most auspicious of starts from Holder, the opening delivery a Harmison-esque wide that evades Chris Gayle at first slip and races away for five wides. A left and right hand opening combination for Ireland with skipper Will Porterfield and thickset Paul Stirling both getting off the mark. Ahead of the run-rate already.

"It's been a magnificent knock from Lendl Simmons. He came in on after two wickets fell in three balls and he showed his intent right from the off. He has really got his team out of the mire."
Interval
WI 304-7
Well, from 87-5 in the 24th over it is quite a comeback. There were boundaries in each of the final 17 overs. What will Ireland make of that target? We will find out in approximately 45 minutes.
CENTURY AND WICKET
WI 302-7
A second ODI century from Simmons, sealed with a boundary, and a highly accomplished 83-ball hundred. He departs from the penultimate ball of the innings, caught in the deep. Big Curtly Ambrose is amongst the West Indies backroom staff, applauding his man off.

WI 295-6 (run-rate 6.02)
That won't do much for Mooney's mood, high into the clear blue sky and over the ropes as Simmons moves into the 90s. Russell then chips one high on the bat that bisects two fielders.

"Bowling at the stumps at the death isn't fashionable any more, but I think more people should do it. When you bowl wide of the stumps, there's only one way you can be out - caught."
WI 280-6 (run-rate 5.83)
Burly Kevin O'Brien is straying a bit, offering Simmons too much width and the Trinidadian frees his arms for consecutive boundaries, Russell scything another for good measure and completing an expensive over with a majestic strike many a mile. Big Kev might have to make another century, but he's more than capable as England will attest.

"You normally look for about 10 an over in your last three overs. That would take West Indies up to 291, and they'd be absolutely over the moon with that, considering the position they were in when Dockrell was running through the middle order."
WI 261-6 (partnership 20)
Andre Russell has four ODI fifties to his name, with a best of 92, and as Mooney strays down the leg-side the Windies all-rounder collects a boundary. There is a review for lbw from Ireland but they are not confident and rightly so. The bearded Mooney, despite his injury, is still charging in and chasing everything however.
WI 254-6 (Simmons 79, Russell 2)
The recently retired Australia paceman Brett Lee has been working with the Irish bowlers and it is clear he has had an influence, but Sorensen then sends down a leg-side full toss that Simmons flicks nonchalantly over the ropes. A portly figure in the crowd attempts a spectacular diving catch and fails, but does succeed in flattening two unsuspecting ladies.

Sammy c Dockrell b Mooney 89 (WI 241-6)
But next ball Sammy is caught at mid-wicket for a magnificent 89 from 67 balls, ending a partnership of 154. Mooney is still incensed however. Injured and irascible. But you've just dismissed Darren Sammy, John!
Dropped catch & Six
WI 241-5
A reprieve for Sammy as Sorensen pushes a big hit over the ropes. Mooney is an aggressive looking character at the best of times and his face was not a pleasant sight, contorted in rage. Sammy moves to 89 and now has his highest score in ODIs.

WI 228-5 (K O'Brien 1-52 from 8)
Fifty from 60 balls for Simmons, who then hoicks Kevin O'Brien for the seventh six of the innings. He had played second fiddle to Sammy for the majority of the partnership but his strike-rate for his last 10 balls is a whopping 250. Big over, 22 from it.

"If these two stay at the crease, 270 is certainly within the hunt. It's very important that the Irish hold themselves together here."
WI 206-5 (partnership 119)
Fabulous brute force from Sammy as he drives Stirling back over his head. The ball took barely a second from bowler's hand to crashing into the boundary board.
WI 198-5 (Simmons 44, Sammy 72)
Mooney's right leg is hoisted vertically by the ruthless Ireland physio at the boundary edge. Just the one boundary in the Kevin O'Brien over as Sammy lashes backward of square. The former skipper has a strike rate of 180 from his last 10 deliveries faced.

Pete Naylor: Sammy has been instrumental in getting the Simmons to rotate the strike and keep the scoreboard ticking. His wicket is vital.
Century stand
WI 190-5 (Simmons 42, Sammy 67)
It was always thought the great West Indies opener Gordon Greenidge became even more of a force when injured and Sammy is continuing the mantel, flicking the returning Mooney effortlessly off his pads for four more. The aggressive looking Irish paceman appears to land awkwardly in his delivery stride and he is also now struggling with an injury. The 100 partnership arrives from 104 balls.

WI 180-5 (run-rate 4.50)
Bad back or not, Sammy is still able to launch and Simmons plays a masterful late cut for four more, the best over of the innings for the Windies with 12 from it. "All about the bass" booms out as a prostrate Sammy is prodded and pulled in painful looking fashion by the West Indies physio. It's all about the back. He has a sip of water and the treatment appears to be him attempting press ups and the physio holding him down.

"Both Simmons and Sammy have done exactly what's been required. They've given the West Indies a chance of getting to a decent score."
WI 168-5 (Simmons 33, Sammy 55)
This Saxton Oval in Nelson is a remarkably beautiful ground, with rolling hills beyond in delightful shades of emerald green. I read that Mr Agnew thinks Adelaide is the prettiest in international cricket but this must rival it surely? Burly Kevin O'Brien continues and he is cut away behind square for four by Sammy who punches the air, one of the most demonstrative cricketers of recent vintage, and highly entertaining. He is stretching his back at the end of the over though, worryingly for the Windies.

"Darren Sammy is making George Dockrell bowl bad balls. By hitting him over cover in the last over, he's put him under pressure. He's a very wristy player, he doesn't move his feet much, just throws his hands through the line of the ball."
WI 163-5 (partnership 76)
Sammy is not one for the purist's coaching manual but he has phenomenally strong forearms and he whips Dockrell for successive boundaries into the leg-side, completing his half century from 45 balls with a single off the final ball of the over, slightly denting the left-arm spinner's figures, which are still a very respectable 3-50.

Glen Towler: I never thought I would see the day that the mighty West Indies would be doing so badly against Ireland.

Six
WI 152-5
A momentary frisson of excitement as the Windies scamper a tight single and Gary Wilson's shy at the stumps strikes the diving Darren Sammy in an, ahem, very vulnerable area. Then an extraordinary shot from Simmons as he eyes up a bouncer from O'Brien and uppercuts it powerfully to the point boundary for six. This is a very handy partnership for West Indies.

WI 137-5 (run-rate 3.91)
Ireland rattling through the overs and cranking up the pressure. Simmons, usually a fluent player, cannot get the persistent Stirling through the packed in-field but again the final ball of the over is a bad one and is cut to the boundary. "Footloose" comes over the public address, but the footwork was exemplary for that cut shot.

Metronomic McBrine continues, just 21, and three singles are all that he concedes. He has completed remarkable figures of 0-26 from his 10 overs against this collection of West Indian cavaliers.
