Leicestershire moved joint top of Twenty20's North Division by beating Yorkshire at Headingley, despite a sparkling innings of 66 from home opener Michael Lumb.
The Foxes, who won by 21 runs with three balls remaining, are level on points with Nottingham-shire, while Yorkshire now need victories from their last two group matches in order to feel confident of qualifying for the last-eight draw.
Chasing a 156 target, Yorkshire could not find anyone to keep company for long with Lumb who played strokes of the highest quality. He reached his half-century off 39 balls and had hit 12 fours when he was sixth out, lofting Jeremy Snape to HD Ackerman at mid-on. It was Lumb's highest score in Twenty20 cricket, and his departure spelled the end for Yorkshire who were dismissed for 134.
Despite Lumb's majestic batting, the man-of-the match award went to wicketkeeper Paul Nixon for his cleanly-struck 52 out of Leicestershire's 155 for eight after the visitors had won the toss.
Tight bowling by York-shire's pacemen restricted Leicestershire to 52 for two from the first nine overs but Ackerman (45 from 41 balls) helped Nixon add 64 for the third wicket. Nixon struck another six off Darren Lehmann to go to his half-century off 38 balls, with four fours and three sixes, but he departed next ball.
