Defending Friends Life t20 champions Leicestershire's miserable defence continued on Wednesday as they slipped to yet another defeat, this time at the hands of Yorkshire.
The Foxes slumped to their fifth defeat in six games in the North Group clash after Yorkshire claimed a nailbiting four-run victory in a last-ball thriller at Grace Road.
Leicestershire needed nine off the last over to reach their target of 152, but managed only four runs off Mitchell Starc, to finish on 147-9, having restricted the White Rose to 151-9.
The victory took Yorkshire to the top of the group and the final over of each innings proved decisive. The visitors scored 16 runs off the last six balls sent down by Abdul Razzaq, with Richard Pyrah hitting sixes off his first two deliveries.
Four run outs did not help Leicestershire's cause either, but they looked on course for victory when Ramnaresh Sarwan and Wayne White shared a fifth wicket stand of 56 - the only half-century partnership of the game.
But Sarwan, having hit 39 off 33 balls, was run out when he was sent back by White and from that point on the game swung Yorkshire's way.
Leicestershire were still very much in it when they required just 17 runs off the last two overs with five wickets standing, but an excellent last over from Starc put paid to their hopes.
He bowled White for 22 off 20 balls and then flattened Nathan Buck's stumps with his final delivery to clinch victory and finish with figures of 2-19.
Leicestershire bowled and fielded well to keep Yorkshire in check for much of their innings, with Buck taking 3-28 in his first game in the competition this season.
Razzaq claimed 3-37, but his final over that went for 16 proved crucial, even though three wickets came in it as well.
David Miller top scored for Yorkshire with 37 off 35 balls while Pyrah hit 35 off 23 balls and was named man of the match.
The result leaves Leicestershire bottom of the table and, with only four games left, they look to have little chance now of reaching the quarter-finals.
