Top billing goes to Marcus Trescothick who sets a new Somerset record with his 50th first-class century for the club and is there at the end with 46 not out in the second innings at Taunton as they avoid defeat by Warwickshire after having to follow on.Copyright: Rex Features
Australian Peter Handscomb is another to shine with the bat, making 101 not out off 77 balls, in the drawn Roses match at Old Trafford.
In Division Two, Worcestershire complete an impressive innings victory at Derby, while Glamorgan's Colin Ingram and Chris Cooke bat through the entire day for unbeaten centuries at Cardiff to deny Notts a fourth succesive win.
Top scorer, though, is Sussex's Luke Wells with 258 on day two against Durham in his first match for several months because of injury. And our BBC local radio commentary team will be in their seats at Hove tomorrow to provide continuing ball-by-ball coverage of that match,
For now, though, thanks for your company.
Yorkshire 448-8 dec & 177-1 dec v Lancashire 432
Surrey 313 & 339 v Middlesex 411 & 92-2
Warwickshire 413 v Somerset 230 & 86-1 (following on)
Derbyshire 275 & 98 v Worcestershire 415-9 dec
Worcestershire won by innings & 42 runs
Nottinghamshire 448 v Glamorgan 187 & 420-5 dec
Leicestershire 420 & 61-2 dec v Kent 462-9 dec
Durham 287 v Sussex 452-4
Day two only, match continues on Tuesday
Sussex score 409 runs in the day against a depleted Durham attack, minus injured Graham Onions, to lead by 165 at the half-way point of the game.
South African Stiaan van Zyl reaches stumps on 141 not out, his maiden first-class century for the county, after a boundary off Ryan Pringle in the penultimate over, having earlier put on 376 with Luke Wells, one of two late victims for Paul Coughlin after making 258.
Luke Wright's side lost their first two Championship games of the season, but have now built a position from which victory is a distinct possibility, unless Durham find some batting heroes of their own against a strong Sussex seam attack.
Having waited so long for a wicket, Paul Coughlin takes two in successive overs for Durham. Sussex skipper Luke Wright registers a four-ball duck as wicketkeeper Stuart Poynter takes a good catch down the leg-side. Sussex lead by 135 as Michael Burgess comes to the middle.

So Michael Yardy and Murray Goodwin keep Sussex's third-wicket partnership record (see previous entry) as Luke Wells finally holes out in the deep off Paul Coughlin. He batted for just over six hours, faced 311 balls and hit seven sixes and 34 fours.
Stiaan van Zyl is still there on 127 not out as skipper Luke Wright, who presumably has been sitting with his pads on for the last 87 overs, comes out to join him.
There are eight overs left in the day's play at Hove.
Sports reporter, BBC Sussex
Much time spent thumbing through the record books at Hove as Luke Wells beat his previous career-best of 208 at The Oval in 2013, and together with Stiaan Van Zyl has added an 376 so far for the third wicket
The county third-wicket record is 385 by Michael Yardy Yardy and Murray Goodwin set in 2006.
Mystifying scenes at Lord's where the game continues several overs beyond the point where a victory for either side was possible.
Set 242 to win off 39 overs, Middlesex opted to bat out time and Dawid Malan (67*) and Stevie Eskinazi (31*) put on 61 in 16 overs before the teams finally shook hands.
Middlesex take 13 points from the game and Surrey, who began it as Division One leaders, earn 11 to lie second, one point behind Essex, who beat Hampshire by an innings on Sunday.

Thanks for your contributions.
It was a day which at one stage promised the possibility of a result, as Warwickshire bowled out Somerset for 230 - still 34 short of the hosts' follow-on target
Young seamer Grant Thornton picked up four of those wickets and, when Somerset's overseas player Dean Elgar gifted an easy catch to Ian Bell in the second over, to give another Bears debutant Sunny Singh his first wicket, Warwickshire thought they might be on to something.
In the end, a much needed knock of 35 not out from home captain Tom Abell brought him his highest score of the season.
And, barely half an hour after completing his Somerset record-breaking 50th Championship century Trescothick was still there unbeaten on 46 in the second innings when the players shook hands.
Luke Wells reaches 200 off 289 balls with a boundary to third man and celebrates with a six from James Weighell's next delivery. A couple of singles in the next over carries him past his previous career-best of 208. What a day for the left-hander, whose father Alan and uncle Colin served Sussex with distinction for many years.
With so much time lost to rain on the first two days, a draw was the only realistic result at Grace Road, but both sides earn 13 points, thanks to some positive batting.
Kent's Darren Stevens made 100 off 98 balls against his former club and there were half-centuries for Adam Rouse (60), James Tredwell (55) and Matt Coles (56 not out off 38 balls) before the visitors declared 42 runs in front.
Will Gidman dismissed Paul Horton for 40 in Leicestershire's second innings, caught behind by substitute keeper Ollie Robinson, and the game came to an end after Harry Dearden's dismissal by Matt Hunn for 17.
Hats off to Colin Ingram and Chris Cooke, who bat through the entire day at the Swalec to earn Glamorgan a draw and end Nottinghamshire's 100% start to the Division Two season.
South African Ingram ends on 155 not out, having batted for just seven minutes short of 10 hours, while Cooke is unbeaten on 113 - and their stand of 226 is a county sixth-wicket record against Notts.
The two teams shake hands on the draw after a brief spell of Michael Lumb's occasional spin for the visitors, for whom England's Stuart Broad sends down 34 overs for figures of 0-55.
Notts take 10 points from the game, and Glamorgan seven.
Peter Handscomb hits his first century for Yorkshire.
One of the more rapid Roses match centuries, off just 76 balls, with 12 fours and one six, in an unbroken stand of 153 with Alex Lees (62*).
Then, four balls later, with Australian Handscomb on 101, it's game over, and the two sides shake hands on a draw.
Having denied Yorkshire any chance of a second win in four matches when they avoided the follow-on earlier in the day, Steven Croft’s Lancashire remain unbeaten in four matches this season. But they have still not beaten Yorkshire in Championship cricket since their title-winning season of 2011.
Michael Lumb comes into the attack for Notts at Cardiff - so everyone bar Riki Wessels and wicketkeeper Chris Read has now turned their arm over.
It's looking increasingly likely that Colin Ingram (153*) and Chris Cooke (112*) will succeed in batting through the entire day in tandem, thereby securing the draw for Glamorgan.
Their lead is now 158 and the visitors' hopes of making it four wins out of four are about to be dashed.
You suspect that Durham will be glad when this day is over. Luke Wells collects two boundaries in three balls from James Weighell to go past 150. Another boundary follows at the start of the next from partner Stiaan van Zyl and they have now added 257 together. The new ball hasn't made any difference so far, and there are another 20 overs to go in the day.
Worcestershire demonstrated their promotion potential at Derby earlier this afternoon by securing a third successive Championship win.
Skipper Joe Leach took nine wickets in the game and after Derbyshire were bowled out for 98 in their second innings, he told BBC Hereford & Worcester: "We are on the crest of a wave at the moment and we need to make sure we keep on riding it.
"I've learnt over the years that momentum in the four-day game plays a massive part and we knew if we could get 140 ahead there would be a lot of pressure on them to defend their wickets.
"Once you get on a roll, things go for you but we worked really hard over three days to get there."
It didn't appear as if Middlesex were going to try and chase down their target, but maybe a rush of blood by Nick Compton suggests otherwise. Mark Footitt bangs in a short ball and the England batsman picks out deep backward square leg.
The reigning champions need 211 from 27.5 overs - but do Surrey believe they can take eight more wickets to snatch the win for themselves?
There's still time for a few more of your movies-themed cricket XI suggestions...but here are another couple.

Glamorgan aren't going to win this match, but it has been a memorable one for the team and supporters alike. Chris Cooke collects a boundary off Jake Libby in the first over after tea to reach a 228-ball century, the fourth of his career in first-class cricket.
The partnership with Colin Ingram (139*) is now worth 193 and the Welsh county are 126 in front.
