Matt Critchley six-for seals deal for Derbyshire at Leicestershire

Legspinner Matt Critchley picked up career-best figures of 6 for 73 as Derbyshire extended their lead at the top of the North Group by completing a nine-wicket victory over Leicestershire in the Bob Willis Trophy match at the Fischer County Ground, Grace Road

Critchley had Colin Ackermann caught at first slip by a diving Wayne Madsen, Ben Mike caught at second slip by Leus du Plooy and Dieter Klein caught behind by wicketkeeper Harvey Hosein in the space of five balls as the Foxes collapsed from 104 for 2 to 140 for 8. Only a defiant last-wicket stand of 52 between Harry Swindells and Chris Wright, batting with a runner, prevented Leicestershire being beaten by an innings.

The morning had seen a double wicket maiden from first-class debutant Ed Barnes raise Derbyshire's hope of forcing a three-day win. The young Yorkshireman, on loan at Derbyshire until the end of the season, bowled nightwatchman Callum Parkinson off the inside edge as the batsman tried to leave a delivery just outside off stump, and three balls later found the edge of left-hander Ben Slater's bat and saw Madsen hold a waist-high catch at first slip to leave Leicestershire struggling on 34 for 2.

They would have been in even deeper trouble if Leus du Plooy had been able to hold a chance given by Harry Dearden soon afterwards, the batsman edging an attempted cut at a wide delivery from Dustin Melton to second slip, where du Plooy got both hands to the ball but could not hang on.

Dearden played aggressively after lunch, hitting 21 runs off 14 balls and raising a 50 partnership with opener Hassan Azad, but an attempt to clear mid-on off the bowling of Critchley gave Luis Reece a simple catch. Azad followed, leg before wicket on the back foot to the occasional left-arm spin of du Plooy, and the writing was on the wall for the Foxes when George Rhodes tried to clip a full straight ball from Melton through midwicket, missed, and was palpably leg before wicket.

Critchley's three in five made the win all but certain, though Will Davis, Swindells - who finished on a career-best 41 not out - and Wright battled impressively to ensure the home side avoided the ignominy of an innings defeat.

With the pitch offering increasing turn, left-arm spinner Parkinson then had Derbyshire captain Billy Godleman caught behind before Reece and Madsen saw their side over the line for their second win in as many matches.
