Another polished display with the ball and in the field from Yorkshire against Nottinghamshire helped set up the victory at Trent Bridge tonight that secured their place in the quarter-finals of the Friends Life t20 for only the third time.

The Tykes’ fielding has been a major factor in their successful run in North Division, which they now lead by two points with two matches left after chasing down 149 with six wickets in hand and 14 balls to spare.

After Adam Voges elected to bat, Azeem Rafiq’s men did not quite match their landmark fielding display against Leicestershire at Grace Road last month when they affected four run-outs. But it was not far behind.

They pressured Notts expertly as Rich Pyrah and Mitchell Starc returned 1-20 and 1-21 respectively to help restrict the score to 148-6 in good batting conditions.

Phil Jaques then anchored the chase with a season’s best 58 not out off 47 balls.

Not surprisingly, left-arm paceman Starc took his wicket in the final over of the innings – ten of his 16 wickets this campaign have come that way – and skipper Rafiq also added 2-33.

Voges top-scored with 70 off 57 after Joe Root had Rikki Wessels caught at mid-wicket by Pyrah with the very first ball of the match.

By contrast, Adam Lyth hit Graeme White’s left-arm spin for three fours in the first four balls of York-shire’s chase.

Lyth holed out off Steven Mullaney for 33 in the seventh, but it was only a minor blip as Root swept Samit Patel for four and reverse swept the same bowler and Mullaney to the fence in his first six balls.

Three wickets fell within the space of 14 balls to leave the score at 107-4 in the 14th over. But any jitters were short-lived as Jaques and Gary Ballance shared an unbroken 43 in 3.5 overs for the fifth wicket ahead of tomorrow night’s clash with Lancashire at Old Trafford.

Meanwhile, Martyn Moxon admitted he was still unsure about David Miller’s availability for finals day if Yorkshire reach it. The South African’s name is included on a list of players thought to be keen to take part in a Sri Lankan Premier League tournament.
