Warwickshire tightened their hold on third place in the First Division of the Norwich Union League by taking swift and emphatic revenge for their C & G Trophy semi-final defeat at Taunton.

Openers Nick Knight and Mark Wagh blasted the visitors out of the water with an unbroken century partnership to clinch a ten-wicket win with 25 overs to spare.

Somerset suffered a pre-match blow with the absence of Mike Burns because of chickenpox and merely escalated the problem with their undistinguished demise for 120.

Dougie Brown and Alan Richardson claimed three lbw dismissals in 11 overs and Warwickshire's seamers became so dominant on an unreliable pitch that the innings included as many as a dozen maidens.

Richardson flattened Keith Parsons' middle stump and came back to bowl last man Jamie Grove for a league-best return of 3 for 17 in his first one-day game of the season.

Matt Wood survived Somerset's mishaps - which peaked when Rob Turner was sent back and run out by Trevor Penney - and made a resolute 29 before lapsing himself with a loose drive to short mid-wicket.

His wicket went to off-spinner Neil Smith during a stint of 3 for 19 and, despite a useful 15 not out by Peter Trego, Somerset folded two balls short of completing their 43-over allowance.

A short break for rain with the last pair together meant that Warwickshire were set a revised 119 for their sixth win of the season. This turned out to a cruise.

Wagh, dismissed for nought in his three previous league innings, found his form with 15 fours in a one-day personal best of 70 and Knight reached 40 in his first appearance since he was struck on the head by a ball from Andy Caddick in the Trophy semi-final.
