Lancashire 196 for 4 (Prince 80*) beat Derbyshire 190 for 9 (Madsen 78, Lilley 4-30, Kabir 4-37) by six wickets
Lancashire boosted their hopes of reaching the Yorkshire Bank 40 semi-finals for the second year running with a resounding six-wicket win over Derbyshire at Old Trafford.
The Lightning returned to this competition following a break for the Friend's Life Twenty20 targeting four wins from their last four Group B matches to give them a chance of progressing - and things began well on Tuesday. After comfortably chasing down 191, they have now won four matches on the bounce in the 40-over format, with former South Africa international Ashwell Prince top-scoring with an unbeaten 80 off 75 balls.
Offspinner Arron Lilley and ex-England quick Kabir Ali both took four wickets each to help restrict Derbyshire to 190 for 9, although they had been tottering on 92 for 6 after 25 overs. They were boosted by career bests of 78 and 40 from captain Wayne Madsen and David Wainwright, who shared 80 in 12.3 overs for the seventh wicket.
Lilley took 4 for 30 from his first seven overs in this competition, despite debuting at the back end of last season. Ali's 4 for 37 from eight were his best figures since August 2007 when playing for Worcestershire.
Lilley was the one who did the early damage with four of the first six wickets, including Alex Hughes and Tom Poynton in the space of three balls in the 25th over, before Ali returned at the death to take two of his wickets in the last over.
Madsen benefited from being dropped on 12 by Ali from mid-on after a lack of communication with sub fielder Karl Brown running around from mid-off. Ali got his hands on the ball bowled by Tom Smith before colliding with his colleague, who was trying to get out of the way.
Right-hander Madsen hit five fours and a straight six off Steven Croft in his 92-ball innings, which ended when he cut Ali to backward point in the 38th over.
Lancashire openers Stephen Moore (34) and Smith shared 53 in 8.3 overs to get their chase off to an excellent start before falling to Wes Durston's offspin to leave the score at 86 for 2 in the 17th. But despite the loss of Simon Katich and Croft to Madsen and Tim Groenewald later in the chase, Prince's presence at the crease meant Lancashire were always cruising as he posted his fourth score above 50 in the competition.
He hit six fours and two sixes before Jordan Clark finished the match off with two sixes off Hughes' medium pace as Lancashire won with 26 balls to spare.
