Phew. Another pulsating day of top-tier cricket is in the books... oh, and there was apparently some Ashes action at Old Trafford too.
It's gearing up to be a fascinating County Championship title race with Division One leaders Surrey and closest challengers Essex and Warwickshire all trying to take a stranglehold of their matches while it was largely a day of toil for the division's bottom three, with Kent, Middlesex and Northants already facing an uphill battle after the opening day.
We'll be back at 10:45 BST to bring you all the action from day two.
Close of play at Trent Bridge
Notts 87-5 v Hants 166
Tom Moores plays out a maiden from Ian Holland, and that is that for day one in Nottingham.
The hosts were firmly in command for the majority of the day, bowling Hampshire out for just 166, and then moving to 47-1 in reply.
However, an excellent spell late on from Holland saw him take four wickets, peg Nottinghamshire back, and bring the game back into the balance.
WICKET Montgomery c Brown b Holland 6
Notts 84-5 v Hants 166
Matthew Montgomery has been given out caught behind off the bowling of Ian Holland here, but the Nottinghamshire batter cannot believe it.
Holland gets one to nip away, and Hampshire celebrate wildly behind the stumps, so there must have been a noise, but Montgomery is adamant he hasn't hit it.
Holland now has 4-19 from his six overs.
Post update
Notts 80-4 v Hants 166
Kyle Abbott gets a little bit full, and Tom Moores belts him through the covers for four.
If it's there to put away, Moores will do so, regardless of the fact the close of play is looming.
Division Two update
#bbccricket
After a nightmare start for the visitors, Fynn Hudson-Prentice and Nathan McAndrew have combined to haul Sussex back from 76-6 to reach 120-6 at stumps at Headingley.
Matthew Fisher has 4-53 for the hosts on a day when only 42 overs were possible due to the weather.
Incredibly, despite being bowled out for only 178 on the opening afternoon, Worcestershire have hauled themselves into a commanding position at stumps on day one at Oakham.
Dillion Pennington has taken 3-24 in the evening session and hosts Leicestershire are 88-8, still 90 runs behind. Rehan Ahmed (25 not out) has provided the majority of the resistance.
Earlier Brooke Guest reached stumps unbeaten on 145 as Derbyshire closed on 317-6 against leaders Durham.
Close of play at Lord's
Middlesex v Surrey 312-5
Jamie Smith's superb unbeaten century has given Surrey the initiative on an opening day on which the momentum has swung back and forth.
Middlesex won the toss and bowled well but were not able to take all the chances they created and Rory Burns (79) steered the Surrey ship through the opening session before Smith took over in the latter part of the day to reach 120 not out from 173 balls at stumps. Jordan Clark has 34 from 60 at the other end.
Tom Helm claimed three wickets and Ryan Higgins took two and a superb catch but Middlesex will have to find a way to take five more wickets against a talented tail tomorrow, with 14 overs left in the chase for bonus points.
Close of play at Edgbaston
Warks v Lancs 295-7
When Danny Lamb was caught behind off the bowling of Ed Barnard earlier this afternoon Lancashire were 150-7 and in danger of posting a below-par first-innings total.
However, that brought Tom Bailey to the middle to join George Balderson and the pair have batted brilliantly to put on 145 for the eighth wicket, and swing the momentum firmly towards Lancashire.
Balderson closes the day 94 not out, and will be eyeing a first first-class hundred tomorrow morning.
Tom Bailey could well achieve the same fate should he carry his form into day two. The 32-year-old is unbeaten on 75 overnight.
WICKET Clarke c Brown b Holland 0
Notts 53-4 v Hants 166
What an end to the day for Hampshire!
Joe Clarke, having just seen Ben Slater nick off at the other end, falls to the same fate for a six-ball duck.
This late burst from Ian Holland has brought the visitors right back into things.
WICKET Slater c Brown b Holland 31
Notts 52-3 v Hants 166
up for Surrey
Middlesex v Surrey 301-5
Jordan Clark moves to 33 with a four off Ryan Higgins.
It brings up the 300 and with it a second batting bonus point for the visitors. Still 16+ overs left to chase the remaining three too.
Two overs to come tonight.
Close of play at Northampton
Northants v Somerset 351
Those two quickfire wickets not only wrapped up the Somerset innings, but also wrapped up the day's play at Northampton.
Somerset will feel they could, and perhaps should have posted a bigger total, but they are the side in control of this game.
Close of play at Chelmsford
Essex 106-0 v Kent 207
Big shout for LBW from Arshdeep Singh against Nick Browne to start the final over of the day... might have been a touch high, was it heading down leg?
Either way, Browne survives, and then taps, and I mean taps, Arshdeep back past the stumps at the other end for four. That is timing.
Browne removes his lid after the penultimate ball and has another chat with the physio but he's ok to face the final ball. A dot.
Essex's day. Sam Cook's sublime 3-19 and 3-47 from Jamie Porter helped bundle Kent out for 207 and Alastair Cook (64*) and Brown (31*) have taken the hosts within 101 at stumps with 10 wickets remaining - one of them will be Dan Lawrence, newly released by England.
WICKET Bashir lbw b Taylor 0
Northants v Somerset 351
Another Tom Taylor yorker striker Shoaib Bashir full on the boot right in front, and that's the easiest of lbw decisions for the umpire.
Somerset are all out, and Craig Overton is left stranded on 40 not out.
WICKET Henry b Taylor 7
Northants v Somerset 351-9
A big swing and a miss from Matt Henry, and Tom Taylor's yorker crashes into the base of middle stump.
That's as out as it gets.
WICKET Young b Holland 13
Notts 47-2 v Hants 166
The curse of the live-text commentator strikes!
It's short and wide from Ian Holland, and Will Young can only inside edge his attempted cut shot onto the stumps.
He swishes his bat in frustration as he trudges off.
Post update
Notts 43-1 v Hants 166
Nottinghamshire have responded well to the dismissal of Haseeb Hameed early on in their innings.
Ben Slater has moved to 26, and alongside Will Young, is building a handy platform for the hosts to build a big first-innings lead.
Close of play at Derby
Division Two latest
Derbyshire batter Brooke Guest goes to stumps unbeaten on 145 as his side close on 317-6 against leaders Durham.
Worcestershire are fighting back superbly with the ball against Leicestershire after being bowled out for 178. Leicestershire have just fallen to 66-6 at Oakham School.
Yorkshire seamer Matt Fisher has just picked up Sussex's sixth wicket and his fourth at Headingley.
Sussex are in all sorts of bother on 76-6.
Nick Browne hit in the head
Essex 100-0 v Kent 207
The Essex 100 comes up via two head byes...
Nick Browne tries to duck a bouncer from Arshdeep Singh but the ball smashes into the crown of his helmet and bounces over the slips.
Browne wants to carry on but the umpires insist upon following the concussion protocol. Out come the medics and Browne is asked all sorts of testing questions, I'm sure.
He's fine to continue, however.
WICKET Gregory c McManus b Broad 48
Northants v Somerset 342-8
Lewis Gregory has batted excellently, but fiddles at one outside off, and nicks through to Lewis McManus.
Matt Henry joins Craig Overton in the middle for the final overs of the day.
Post update
Essex 97-0 v Kent 207
Just over three overs remaining and Alastair Cook and Nick Browne will be desperate to reach stumps unbeaten.
The Kent lead is down to 110 but Essex have all 10 wickets standing. If they can complete their challenge they will be able to play more expansively tomorrow, you'd expect, plus they will be able to call on Dan Lawrence, understood to be heading back to Chelmsford from Manchester this afternoon.
