County Championship (at Edgbaston): Somerset 268 & 183 beat Warwickshire 140 & 130 by 181 runs.
Somerset 21 pts, Warwickshire 3pts.
Murali Kartik continued a one-man crusade against Warwickshire with a match return of 11 wickets for 72 runs at Edgbaston as Somerset wrapped up a quickfire double in the LV= County Championship.
Having taken six for 61 in a nine-wicket at Taunton last month, the left-arm spinner bowled the West Country men to victory by 181 runs despite a lengthy hold-up following a mid-afternoon downpour.
Marcus Trescothick's side, now third in Division One after a third win of the season, continued to dominate the return meeting after setting Warwickshire a target of 312 on a wearing pitch.
With Varun Chopra making 46 - his highest score since moving from Essex - they offered some resilience in the second innings but still slumped to their fifth defeat of the summer when bowled out for 130 on the third day.
The pitches at Edgbaston this year have favoured bowlers and Warwickshire, having lost the toss in each of their home games, have consistently been at a disadvantage. Although upsetting the odds in beating Hampshire, they have now been beaten three times at their headquarters.
Throughout this game Somerset were stronger than a Warwickshire side who missed chances on the first day and slipped deeper into trouble on day two as 17 wickets fell on a deteriorating surface.
When Somerset resumed at 151 for eight, they eked out 32 more runs thanks to all-rounder Ben Phillips, who completed a brisk half-century with a six on to the roof of the Eric Hollies Stand.
Imran Tahir finally claimed the last two wickets to complete a return of six for 58. Kartik speared a catch to cover after contributing 32 to a stand of 56 with Phillips, who was stumped for 55 after hitting six fours and two sixes from 85 balls.
Set to make the highest score of the match, Warwickshire needed a good start, but for the 12th time in 16 Championship innings this summer, their opening partnership failed to reach double figures.
The blow of losing Darren Maddy - neatly taken by Trescothick at first slip - was softened when Chopra and Ian Westwood held up Somerset for 22 overs.
In the conditions it was a good effort to put on 57 before Phillips made another intervention by removing Westwood for 22 with a good catch by wicketkeeper Craig Kieswetter.
After playing well for more than two hours, Chopra was unlucky to be dismissed when a ball from Alfonso Thomas kept a shade low.
Warwickshire's hopes then plunged as left-arm spinner Kartik claimed three wickets in four overs. At this stage the only threat to Somerset was the rain which kept the players off the field for more than two-and-a-half hours.
However, they were able to resume in bright sunshine at 5.55pm. Chris Woakes (21) despatched the first two balls for boundaries but was then lbw to Kartik and in the next over Richard Johnson edged Charl Willoughby to first slip.
Tahir and Andrew Miller surrendered their wickets to catches in the deep off successive deliveries from Kartik, giving the Indian six for 42 to supplement his first innings figures of five for 30.
