Nottinghamshire 115 for 2 (Wessels 63, Moores 41*) beat Derbyshire 110 (Madsen 37, Critchley 33, Ball 4-29, Carter 3-19) by eight wickets

As East Midlands derbies go, this one will go down as one of the great mismatches. Derbyshire's players will hope to file it along with other brain fades such as telephone banking passwords and where their car keys are. A calamitous batting display saw them wafted aside for 110 on a sunny afternoon, leaving Nottinghamshire, the holders, to scamper to a place in the play-offs with an eight-wicket victory.

That win came with disparaging haste as Notts endeavoured to lift their net run rate and thereby claim a home tie in the play-offs by finishing second in the group - it later transpired, successfully. Riki Wessels set the tone by striking the first four balls of Hamidullah Qadri's second over straight for six - the over went for 28 - and to ribald cheers the game was settled within 11.5 overs. Wessels made 63 from 34 balls and Tom Moores caught the mood, batsmen with the licence to have a bit of fun.

Derbyshire have had worse derby disasters. They were once bowled out for 16 on this ground, still their lowest total, as Fred Morley took 7 for 7 in 1879. Morley was regarded as the fastest bowler in the land and, had he not died of dropsy five years later, he might have fancied picking up a couple of wickets here, such was the ineptitude of Derbyshire's display.

"It's unacceptable to be bowled out for just over 100," said Billy Godleman, Derbyshire's captain. "The surface was an interesting one and posed challenges, particularly when the seamers were bowling."

At least Derbyshire brought some cheer for England. Jake Ball, Nottinghamshire's tall, languid pace bowler, has replaced Chris Woakes in England's ODI squad for the Australia series and he loosened up with four wickets. There was an uplifting sight, too, for Peter Such, the ECB's lead spin bowling coach, who was delighted to see Matthew Carter's stately offspin reap three wickets too.

Carter is one of England's forgotten spinners, his progress hindered by the Championship's banishment, by and large, to the start and end of the season. But he came into this match with two Royal London Cup four-fors this season and looked in good order. He is a tall man who just walks up the wicket with deliberation, but his rhythm was excellent and he drew turn from a used surface. He should get a Championship outing at Taunton this weekend and can still have a fine career ahead.

Godleman was the Derbyshire wicket most sought, his tournament record standing at 505 runs at 84.16, but the captain only added four more, Carter drifting the ball into the left-hander then finding bite to have him caught at slip. Alex Hughes obligingly hacked a ball turning down the leg side to midwicket and Carter returned later to defeat Hardus Viljoen's rustic heave.

With Ball having Ben Slater caught at the wicket, Derbyshire were three down within 4.5 overs, their two batsmen who have dominated their 50-over season both gone and hopes of sneaking a top-three spot already retreating. Matt Critchley played brightly for 33 before chopping at Luke Fletcher's wideish outswinger and the most surprising shot of all came from Wayne Madsen, who was his usual reliable self in making 37 only to heave Ball to long on in suicidal fashion.

There were other giveaways too: a sweep down deep square leg's throat by Gary Wilson, a leave alone against Ball by Darren Smit, although as Ball himself remarked after a second look, that one did come back a bit. Derbyshire didn't even make it last until the rush hour had departed, leaving their supporters to queue up the A52, adding their own fumes of dismay to the evening pollution.
