Warwickshire Bears were bowled out for 73, their lowest Twenty20 total, as Somerset romped to a 10-wicket win at Taunton to keep alive their hopes of appearing in a fifth straight Twenty20 finals day.
Warwickshire had never previously been dismissed for fewer than three figures in a 20-over match - but were rolled inside 17 overs as Yasir Arafat took 4-5 for Somerset.
Somerset's chances of qualifying from the Midlands/Wales/West Group of the Friends Life t20 had been damaged by three defeats in a row, but back-to-back wins over Glamorgan and Warwickshire have lifted them firmly back into contention.
The hosts were rampant with the ball, reducing their visitors to 13 for five inside five overs courtesy of an incredible spell in which four wickets fell for one run in the space of nine deliveries.
Only two Warwickshire batsmen - Rikki Clarke and Darren Maddy - made more than five as the visitors capitulated against Somerset's seam attack.
Yasir Arafat had Varun Chopra held at deep backward square-leg in his first over and sent back Will Porterfield and Laurie Evans in his next set of six.
Alfonso Thomas followed his fellow veteran’s efforts with a double-wicket maiden that saw Nick Compton take a wonderful diving catch at backward point to account for Chris Woakes and Ateeq Javid edged to the second of three slips.
Warwickshire's first boundary arrived in the eighth over, as Maddy and Clarke set about restoring some pride. They added 48 in nine overs before Maddy holed out off Steve Kirby for 20.
In the next over, the 15th, Steffan Piolet edged Craig Meschede behind for a golden duck and Clarke holed out to Peter Trego at long-on.
Jeetan Patel was bowled by a Max Waller googly for five and Boyd Rankin edged Arafat behind off the final ball of the 17th over as Warwickshire were dismissed for 73.
Somerset reached their target with minimal fuss in 8.3 overs as Kieswetter scored 39 from 27 balls and Chris Jones added 30 from 26.
To sum up Warwickshire's woe on a dismal day for them, victory was sealed when Piolet sent down six no-balls, the ball flying over the head of wicketkeeper Peter McKay and running to the boundary.
