Somerset's Nick Compton completed 1,000 runs for the LV= County Championship Division One season with a century against Worcestershire - just a day after the coveted end-of-May milestone.
Compton was nine not out and watching the rain fall as the month's action came to its end, denying him the chance to become only the ninth man to achieve that feat, but vented his frustration today by making 108 before being bowled by Jack Shantry (four wickets for 56 runs).
He put on 75 with James Hildreth (52) and 167 with Jos Buttler (85) to lead his side to 277 for seven, 63 runs behind the hosts' first-innings total.
Lancashire made good inroads into a target of exactly 200 to win their low-scoring thriller against Durham at Chester-le-Street.
The hosts had been dismissed for 102 in their first innings and conceded a deficit of 68, but Ben Stokes (121) underpinned a more respectable second effort with the bat.
Paul Collingwood offered good support with 50 as the hosts reached 267, Luke Procter and Simon Kerrigan taking three wickets apiece, but the Red Rose recovered from losing Paul Horton to the first ball of their innings to reach 56 for one.
Middlesex were in control against Sussex at Lord's after a score of 491 featuring excellent contributions throughout their batting order.
Chris Rogers added just five to his overnight 93 but Eoin Morgan (71) and Gareth Berg (45) played their part before Ollie Rayner (69) and Toby Roland-Jones (52) put on 76 for the ninth wicket, the latter hitting five fours and a six in a 63-ball maiden first-class half-century.
That gave the hosts a first-innings lead of 208 and Steven Finn removed Ed Joyce as they had their opponents 34 for one when bad light ended play early.
In Division Two, Gloucestershire picked up their second win of the season as they routed previously unbeaten leaders Derbyshire by seven wickets with a day to spare at Bristol.
The visitors were deep in trouble from the moment they were bowled out for 95 on the first day and, although they reached 283 in their second innings, they could only set the home side 85 to win.
Jon Batty went in the first over for a duck but Benny Howell (31) and Kane Williamson (29) saw off the bulk of the target and Alex Gidman and Hamish Marshall finished the job, earning their side 21 points to Derbyshire's three.
Michael Thornely and Ned Eckersley made centuries as Leicestershire batted out the final day for a draw against Glamorgan in Cardiff.
Opener Thornely made 131 before becoming the only wicket of the day, caught by Gareth Rees to give Jim Allenby figures of one for 15 from 14 overs, and wicketkeeper Eckersley was 137 not out at the end with Ramnaresh Sarwan 25no.
Glamorgan, who used 10 bowlers, took 10 points to their opponents' six after making 558 for nine declared in their sole innings.
Opener Joe Root's century gave Yorkshire the upper hand against Northamptonshire as they took a first-innings lead of 163.
Root made 125 and Jonny Bairstow 68 as the Tykes scored 416, Lee Daggett taking four for 109.
Yorkshire old boy James Middlebrook made just nine, for the second time in the match, in his unfamiliar opening role but Northants were 43 for one by the close, 120 behind.
