Warwickshire 149 for 3 (Clarke 40) beat Gloucestershire 145 for 7 (Klinger 68, Javid 3-26) by 7 wickets

Warwickshire kept their hopes of reaching the Friends Life t20 quarter-finals alive while inflicting further misery on Gloucestershire with a seven-wicket win at Edgbaston.

The Bears paced their chase of a 126-run target to perfection with Varun Chopra and William Porterfield leading the way with an opening stand of 68 and Rikki Clarke clobbering 40 from 21 balls.

Gloucestershire's defeat, which ended their own slim hopes of making the knockout stages, followed the decision by an England and Wales Cricket Board pitch panel to deduct them two points from next year's competition for the substandard surface they prepared for their home group match against Warwickshire at Cheltenham on July 14.

The Gladiators, who were shot out for 96 at Cheltenham, were more competitive this time and made 145 for seven after they were put in thanks to captain Michael Klinger's 68 from 52 balls. It took Klinger time to assess the pace of a pitch that Warwickshire used for last Saturday's win over Northamptonshire and the Australia A right-hander managed only 21 runs in the first 10 overs.

But Klinger found his range by pulling Steffan Piolet over the short-midwicket boundary before reverse sweeping Ateeq Javid for a second six. Klinger's third six, swept off Piolet, took him to a 40-ball half century but he perished in the penultimate over of the innings when he was bowled while aiming Jeetan Patel through the off-side.

Apart from Klinger only Ian Cockbain, who also launched Piolet for a six in his 25, really got to grips with Warwickshire's miserly offspinners.

Javid followed up his four wickets at Cheltenham with 3 for 26 and Patel, who bowled Ed Young with his last ball, finished with a season's best 2 for 13.

Chopra and Porterfield's partnership ensured there was no chance of a repeat of Warwickshire collapse against Somerset on Sunday when they were shot out for 73, their lowest Twenty20 total.

Porterfield eased to 34 from 30 balls, comfortably his highest score in this season's competition, but then carved Alex Gidman to Cockbain at point and Chopra also perished when well set, falling lbw while trying to sweep slow left-armer Tom Smith.

Clarke then struck three sixes off Young in what proved to be the decisive over before he picked out deep midwicket, and Darren Maddy guided Warwickshire home with 14 balls to spare.
