Buttler powers Somerset
Somerset virtually guaranteed themselves a Clydesdale Bank 40 semi-final place with a 59-run win under the Duckworth/Lewis method over neighbours Gloucestershire at Bristol.
Jos Buttler was the hero for visitors, smashing an unbeaten 63 off only 39 balls, including 27 off the last over, as Somerset posted 210 for eight in 30 overs in a rain-affected game.
Former Gloucestershire bowler Steve Kirby took three early wickets to ensure that his former county were always well behind the rate before Buttler produced a run-out and took a stunning catch to complete an easy win.
Having been put in, after a heavy shower shaved off 10 overs for each team, Somerset got off to a flyer as Marcus Trescothick and Peter Trego opened up with a stand of 67 in eight overs.
Jon Lewis, playing his final home CB40 match for Gloucestershire before he joins Surrey, eventually had reason to celebrate after an early battering from Trego, who raced to 37 off 27 deliveries before he was caught by Kane Willamson.
Nick Compton and Trescothick fell in successive overs and the visitors lost their way before Buttler's onslaught.
After a slowish start, he saved his best for the final over when he struck David Payne for three huge sixes and a four.
Kirby wasted no time in putting his side well ahead with the ball. He had openers Alex Gidman and Hamish Marshall caught by Buttler in his first over before the pair combined again to remove Williamson for a top score of 23.
Man-of-the-match Buttler also sprinted from behind the stumps to run out Ian Cockbain and took a stunning one-handed diving catch to dismiss Ed Young, who top-edged a sweep on to his body to give Arul Suppiah one of two quick wickets.
Gloucestershire were a long way behind the required rate when more heavy rain moved in. Trescothick ensured that Somerset completed 10 overs to constitute a match and the players left the field for the final time midway through the 12th over on 70 for six.
That gave Somerset a comprehensive win which means that they will now be difficult to catch in Group C due to their imposing net run-rate.
