Your cricket Olympics XI via #bbccricket
Cook out for 4 for Essex
Thanks for joining me for today's County Championship coverage - we'll be back tomorrow at just before 11:00 to bring you all the action from the second day's play.
A reminder that you can read reports of all of today's action on the counties section of the BBC Sport website.
But from me, thanks once again and goodbye for now.
So here we have it, our Olympics-themed cricket XI. Apologies to anyone whose suggestions I've missed off.
Some may question my decision to put showjumper Nick Skelton in at number seven, but if you can win your first Olympic gold medal at the age of 58, then what can't you do?

Division Two (all day one)
Worcestershire v Northamptonshire 345-6
Lancashire 287 v Surrey 50-0
Image source, EmpicsAnd the last of our eight games reaches its conclusion for the day, as Surrey reach 50-0 in response to Lancashire's 287.
Rory Burns is leading the reply on 33, with Dom Sibley set to restart tomorrow on 10.
Leicestershire 238 v Essex 13-2
Essex lose nightwatchman Jamie Porter for a duck after seeing Alastair Cook bowled for four, closing 226 runs behind promotion rivals Leicestershire.
Northants dominated the first day against Worcestershire, thanks mostly to Rob Keogh's brilliant 154, reaching stumps at 345-6.
Sussex resume tomorrow on 111-1 in reply to Glamorgan's 252, while Hardus Viljoen takes his fifth wicket on his Kent debut to bowl Gloucestershire out for 221 at close of play.
Durham 207 v Warwickshire 25-1
Warwickshire will be happy with their efforts on day one against Durham, having made the hosts bat first at Chester-le-Street.
Jeetan Patel, the County Championship's leading wicket taker, did the damage once again with a five-wicket haul.
Durham will need to replicate the visitors' performance with the ball tomorrow to stay in contention, and they'll take confidence from Varun Chopra's late dismissal as the Bears started their reply.
Leicestershire 238 v Essex 10-1
Alastair Cook is out!
Dieter Klein, making his first appearance for Leicestershire in first-class cricket, clean bowls the England captain with an inswinging yorker.
Jamie Porter takes to the crease as nightwatchman.

There have been some excellent suggestions for our Olympics-themed XI today, but this one takes the gold for me.
Bradley Pitts: Ryan tenDoesStarters Orders
I'll have the full teamsheet for you after all today's games have finished.
Yorkshire 282 v Nottinghamshire 38-2
It's finely-poised at close of play between Yorkshire and Nottinghamshire at Scarborough, where the visitors really ought to have been well on top.
Notts had Yorkshire in dire straits at 51-6, before letting them off the hook with tail-enders Azeem Rafiq and Jack Brooks making half-centuries and Andy Hodd scoring an unbeaten 96.
To make matters worse, Jake Libby and Tom Moores have both lost their wicket late in the day, leaving them 250 runs behind with eight wickets in hand.
Hampshire 281-6 v Somerset
Hampshire looked in trouble at 92-4 after choosing to bat first against Somerset at Taunton, but Sean Ervine's 103 helps them recover to 281-6 at close.
Lewis McManus will resume tomorrow unbeaten on 41, alongside Gareth Berg who has 12 runs to his name.
Leicestershire 238 v Essex
Jamie Porter has his fourth wicket, and Leicestershire are all out for 238 in their promotion battle with leaders Essex. England captain Alastair Cook is set to open the batting for Essex in a few minutes' time.
Sussex opener Chris Nash has just reached 50 as his side progress to 90-0 in reply to Glamorgan's 252, while Northants are three overs away from stumps on 337-6 against Worcestershire.
Hardus Viljoen's terrific debut performance for Kent has just got even better - the South African paceman has taken a fourth wicket to leave Gloucestershire 208-8.
Northamptonshire 331-6 v Worcestershire
Worcestershire's bowlers had no answers to Rob Keogh today, but a sharp bit of fielding from Ed Barnard sees him run out for a magnificent 154 at New Road.
The pears' next priority will be to remove Steven Crook, who is going along very nicely with 77 from 113 deliveries.
Durham 207 v Warwickshire
Graham Onions is the last man out for Durham against Warwickshire, caught behind off Jeetan Patel, who finishes with figures of 5-32.
Warwickshire will have 12 overs to see out before close of play tonight.
Yorkshire 282 v Nottinghamshire 1-1
This isn't what Nottinghamshire would have planned for their response at Scarborough.
Jake Libby is given out leg-before to Jack Brooks for a golden duck, after Ryan Sidebottom had bowled a maiden first over.
Debutant Tom Moores, son of former England head coach Peter Moores, comes in at number three.
Hampshire 244-6 v Somerset
Sean Ervine celebrates his second century of the County Championship season, but he's removed lbw by Somerset spinner Jack Leach soon after to leave Hampshire six down for 244 runs.
Yorkshire 282 v Nottinghamshire
Andy Hodd takes a single off the first ball of Brett Hutton's 15th over to move on to 96, but two balls later Ryan Sidebottom is bowled to end the Yorkshire innings.
Hodd's score is his best since joining Yorkshire in 2012, but he'll be disappointed not have reached three figures.
Nottinghamshire might have taken this total at the start of the day after putting Yorkshire in to bat, though they ought to have bowled them out sooner after reducing the hosts to 51-6 earlier.

A last call for you to send in your Olympics XI cricketers using #bbccricket.
It's quite a team already, though one or two more batsmen wouldn't hurt.
Yorkshire 281-9 v Nottinghamshire
No half-century for Jack Brooks, but still an excellent effort with the bat from the Yorkshire seamer before he plays on to his stumps off Brett Hutton.
Andy Hodd is unbeaten on 95 - will he run out of partners before he can complete his century?
Lancashire 239-9 v Surrey
Image source, EmpicsLancashire's innings is drawing to a close at the Oval, where Stuart Meaker gets his third wicket of the day when he draws Aaron Lilley into edging through to the wicketkeeper.
Durham are now eight down at home to Warwickshire, with Jeetan Patel and Keith Barker picking up three wickets apiece for the Bears. The score is 190-8 at Chester-le-Street.
Leicestershire 204-7 v Essex
Leicestershire have lost Ben Raine for 17 since tea, but they've also picked up their first bonus point as they push beyond 200.
Sussex have made a positive start in their reply to Glamorgan's 252 at Cardiff, scoring 42 from their first 11 overs.
Recently-crowned T20 Blast champions Northants are well top of Worcestershire on 283-5, while Gloucestershire are 170-5 at Bristol with 22 overs left in the day against Kent.
