We are back under way at the Madejski Stadium.
Can bottom club London Irish hold on for their third victory of the Premiership season?
You could say the Premiership is the delicious starter to the main course that is the Six Nations.
After wins for France and England yesterday, Ireland and Wales will be looking to start their campaign with a win in the 15:00 GMT kick-off.
Following the conclusion of these two matches, you can follow the match on 5 live sports extra as well as a live text commentary service.
We've certainly created a number of opportunities. I think the strategy we've spoken about during the week is working - we need to be clinical in the 22.
James Short's try and two Gareth Steenson penalties mean that Exeter will be going top if the result stays like this.
Saracens, however, will be buoyed by that try just before the break and will have the strong wind behind them in the second half.
Irish win a penalty off the scrum and kick for the five-metre line - but they cough up possession and Wayne Barnes blows for half-time soon after.
Very much an attritional battle at the Madejski Stadium.
We spent a good few minutes with the Television Match Official there as this was a tricky call.
Italian number eight Samuela Vunisa definitely crosses the line with the ball but there was an issue with the grounding, if it was held and and one or two other bits to sort.
The try is given though as the ball is adjudged to have touched the white try line and Charlie Hodgson is unable to get his get anywhere near the posts in the wind.

London Irish seven points clear with a few minutes left in the first half.
Bonkers few seconds at the Madejski Stadium.
Worcester winger Bryce Heem makes a try-saving tackle on Topsy Ojo, but is shown a yellow card soon after by referee Wayne Barnes - who comically got caught up in play.
Warriors down to 14 men and with a penalty to come...
Pressure has equalled points for Rob Baxter's side.
Another penalty is won, this time from a scrum, and Exeter decide to take the points as they're closer to the posts.
Gareth Steenson boots over his second kick of the afternoon.
London Irish have had numerous line-outs around the Worcester 22 so far today, and they almost get through again, but Topsy Ojo can't get on the end of a kick through - instead Cooper Vuna clears the danger.
Exeter win a couple of penalties 5 metres away from the Saracens try line, but both times they go for the line-out and are just stopped by the defence.
The blue-and-grey shirts of the visitors are holding on a bit here, camped inside their own 22.
Ryan Mills has his side on the board against the Premiership's bottom club with a kick from quite some distance.
In the context of the relegation battle, this match is huge.
Ollie Atkins has the ball down over the try line again for Exeter, but the referee had already blown up for an earlier infringement.
Saracens are certainly getting more territory in this wind but the hosts are on top - apparently they have had over 70% of the possession so far.
Worcester are struggling to get close to their opponent's line, and after a period of pressure in the Irish half, they are penalised for not releasing.
It must be said, when you have a guy as big as Halani Aulika on top of you, it must be hard to roll the ball away...
We've had to wait 18 minutes for the first score, but it was well worth the wait.
Worcester's Chris Pennell tries to break through in his own half, but Irish turn the ball over and Ciaran Hearn spotted a gap, kicks over the top of a couple of Worcester players and ran in unopposed under the posts for his second try for the club.
Shane Geraghty then converts the easiest of conversions.
Former Saracens man James Short continues his excellent recent try-scoring record.
It comes from a Sarries attack as Charlie Hodgson tries to offload close to the try line - but the Exeter winger reads it perfectly and runs the length of the field to touch down.
Gareth Steenson unable to add the extras out wide.
London Irish work the line-out well and keep the pressure up on Worcester, the forwards inching closer to the line before Halani Aulika things he has the ball grounded.
The referee refers upstairs an the TMO rules there was a high challenge in the build up.
Much like in the majority of the games so far this weekend, the weather is causing problems.
Saracens, against the wind, are struggling to get any territory on their kicks at the moment and Exeter are running it back hard.

Saracens' Samuela Vunisa, in for England number eight Billy Vunipola, is penalised for going over the ball and the Exeter number 10 Gareth Steenson slots an easy kick.

Bright start by the Chiefs deep in Sarries territory at the moment.
London Irish have started the match on the front foot, pinning Worcester about five metres from the tryline, but the referee pulls it back for a penalty about 25 metres out on the left-hand side.
Shane Geraghty, though, skews wide of the mark.
We've also had an incredibly late change for Worcester at fly-half as Ryan Lamb starts in place of Tom Heathcote.
We're underway at Sandy Park through Gareth Steenson.
Exeter in their all black home hit while Saracens are in their changed controversial grey and blue outfit.

So, as I mentioned there are consequences at both ends of the table today. Whoever wins at Sandy Park will go top - unless Exeter win and Saracens secure a losing and try scoring bonus point in the same match of course...
Bottom-of-the-table London Irish know if they score four tries today, win and stop Worcester from getting a bonus point then they'll be up to the giddy heights of 10th place.

Replacements: Ellis, Smallbone, Halavatau, Nagle, Guest, Allinson, Williams, Brophy Clews.
Looking at the BBC Weather website for Exeter it could get a little bit wet around Sandy Park today, with light rain expected around kick-off and heavy rain forecast from around 14:00 GMT...
That could make things difficult for both sides to play their rugby, but I don't think Saracens forward Jacques Burger will care too much...
Meanwhile in the clash at the other end of the table, there's a milestone for one London Irish stalwart against Worcester...
BBC Sport at Madejski Stadium
It's not often that coaches openly say a game is a "huge" one, but that's one of the words London Irish head coach Tom Coventry used to describe this meeting of 12th v 10th.
Irish, with just two wins so far this season and no bonus points, know they have to get something from this game to avoid being cut adrift at the halfway point of the campaign.
The face a Worcester side on a run of 11 straight defeats and without an away win against Irish in more than a decade.
