Another sensational innings by Darren Lehmann propelled Yorkshire to a 179-run victory over Nottinghamshire at Scarborough to ease their fears of relegation from the Norwich Union First Division.
Lehmann's innings contained 11 sixes and 24 fours in a record-breaking 191 made from only 103 balls. It was Yorkshire's highest-ever individual score in any form of one-day cricket and the biggest made against Nottinghamshire. His third 50 was hammered off 19 balls.
The blitz lifted Yorkshire to 352 for 6, their highest-ever one-day total. Nottinghamshire were bowled out for 173.
In the County Championship, Somerset moved back into second place in the First Division despite having to settle for a draw against Surrey at Taunton.
The 11 points were enough to give Jamie Cox's team a four-point advantage over third-placed Kent, with both teams having two games left to play.
The Hollioake brothers helped Surrey to safety after they had been set an unlikely victory target of 407 in 83 overs. Their captain, Adam, hit 83 and Ben added 56 to see the visitors to 294 for 6 at the close.
Northamptonshire's spinners gave themselves a First Division lifeline after snatching a dramatic 202-run victory over Leicestershire at Wantage Road.
Set 288 to win, the visitors reached 62 for 3 at tea with the match apparently destined for a draw. But the three-pronged attack of Jason Brown, Graeme Swann and first-class debutant Monty Panesar bagged the remaining seven wickets for 23 to dismiss Leicestershire for 85 with half an hour to spare.
Glamorgan's hopes of closing the gap in the race for the Second Division title were washed out at Lord's. They reached 100 for 3 off just 21 overs when play was halted at 3:15pm through rain and then later abandoned. Sussex suffered their second complete washout of the season as their match against Durham was abandoned at Hove.
