Friends Provident t20 (at Edgbaston): Derbyshire 148-7 v Warwickshire 152-4 (20 overs). Warwickshire beat Derbyshire by 6 wkts

A last-ball boundary by Darren Maddy ended Warwickshire's two-match losing streak in the Friends Provident t20 as they snatched a six-wicket win against Derbyshire at Edgbaston.

Needing 14 from the last over to overhaul the Falcons' 148 for seven, Warwickshire got home after a rare lapse by Charl Langeveldt - the South African with a reputation as one of the best 'death' bowlers in the world.

Langeveldt's fourth delivery was a huge wide, spearing down the leg-side for a boundary, which gave Maddy the opportunity to finish the job with an unbeaten 25.

Acting captain, Jim Troughton led Warwickshire's challenge with 58 from 41 balls in his fifth game since taking over from county skipper Ian Westwood for the duration of the competition.

Troughton was caught on the long-off boundary off Langeveldt after hitting four fours and two sixes, but his partnership of 66 with Jonathan Trott (44) put Warwickshire in contention before the England batsman fell to Tim Groenewald (two for 21).

The fourth pair eased some of the pressure after a double strike by Derbyshire.

Loots Bosman ran out Neil Carter with a swift return from cover and Ian Bell did not have time to benefit from his day release from the England one-day squad.

A loose drive to cover off former Edgbaston team-mate Groenewald cost him his wicket after making two from eight balls.

Derbyshire also had to re-build after a troubled start. In eight deliveries from Carter and Chris Woakes, they lost Wes Durston, top edging to square leg, Bosman and Chesney Hughes, both caught by Troughton at backward point.

Greg Smith (30) and Garry Park (28) partially corrected the situation in a stand of 63 during which the two South African-born batsmen batted sensibly in picking off just seven boundaries in their eight overs together.

Former Derbyshire spinner Ant Botha and left-arm seamer Keith Barker finally nailed the fourth-wicket pair with catches by wicketkeeper Tim Ambrose and Woakes.

Derbyshire still finished with a flourish thanks to a positive approach by John Sadler. In 28 balls the left hander hit two sixes and two fours in an unbeaten 38 and Derbyshire gave themselves a chance by taking 26 from the last two overs.
