What a day of County Championship cricket we've enjoyed, a reminder of why we all love this old competition so much - and it's been a particularly memorable day for Division One leaders Surrey.
They fought from behind to achieve the second largest fourth-innings run chase in Championship history by knocking off 501 as Dom Sibley also broke records of a slower kind with his patiently-crafted 140.
We also enjoyed two thrilling finales in Division Two where Leicestershire beat Gloucestershire and all four outcomes were possible heading into the final few balls of Sussex's barnstormer with Worcestershire.
That's all from us today but make sure you head right back to the BBC Sport cricket homepage on Friday where we'll have coverage of the first Test of the Ashes plus a number of T20 Blast games in the evening.
How they stand - Division Two

Leicestershire and Yorkshire have been the big winners in Division Two.
Yorkshire claimed a first Championship victory in more than a year by beating fellow winless side Derbyshire in an exciting finish.
Leicestershire claimed a late win at Gloucestershire to go third but Durham remain top after their high-scoring draw with Glamorgan.

Surrey chase 501 to beat Kent

Dom Sibley has been speaking to BBC Radio London about Surrey's amazing run chase at Canterbury:
"To chase that many and to win the game, the boys are buzzing and it's great to stay at the top of the table.
"Even when we were set 501 it didn't feel like it was out of our possibilities as a side - all the conversations were extremely positive yesterday and overnight.
On his unbeaten 140 after compiling the slowest County Championship century in history:
"It was just about occupying the crease. I wasn't in any rush and I didn't need to be - and obviously it helps when Smithy [Jamie Smith] comes and plays an innings like that, it was one of the best knocks I've ever seen from the other end, the striking and the shot-making was unbelievable - same with Foakesy today.
"I was just trying to play that anchor role for the knock and the two lads beside me were unbelievable so credit to them.
"That was my first century for Surrey since I was at school so it meant a lot to me - it's been weighing on my mind a little bit and I'm pleased to help the boys get a win."

Well, that comeback win has really boosted Surrey's chances of retaining their Division One title.
They looked in danger of being dragged back towards the chasing pack when they were set 501 to win by Kent but that amazing run chase moves them 32 points clear at the top of the table.
They benefitted from Warwickshire's draw with Notts and Hampshire's defeat by Lancashire.
At the foot of the table, Kent's failure to turn that fantastic position against Surrey into victory leaves them well in trouble after just one win so far this summer.

A very similar thing happened to Leicestershire here in 2021, when they lost in the final session.
Worcs need 24 off 24 balls
Sussex v Worcs 362-6 (target 386)
