Somerset claimed their fourth win from four CB40 games this season with an an eight-wicket demolition of west country rivals Gloucestershire at Taunton.
Craig Kieswetter hit his second one-day century of the campaign as the hosts chased down the Gladiators' 213 all out with all of six overs to spare.
Kieswetter and Marcus Trescothick (50) put on 96 for the first wicket in 14 overs, with Kieswetter going on to make 108 not out, facing 102 balls and hitting nine fours and four sixes. He has now scored 308 runs in four CB40 innings this season.
Trescothick hit six fours in his 51-ball innings and looked to be finding it almost too easy when he was out lbw, carelessly sweeping a straight ball from Richard Dawson.
Peter Trego also gave away his wicket with a loose shot but Nick Compton eased his way to 36 not out in an unbroken stand of 84 with Kieswetter that settled any doubts about the outcome.
Kieswetter was dropped on 39 and 85, but went on to reach his hundred before hitting the winning runs with his fourth six.
Gloucestershire's total had been based on a second-wicket stand of 117 in 24 overs between Alex Gidman and Kane Williamson.
Gidman top-scored with 66, with Williamson making 47, while Lewis Gregory returned career-best figures of 4-27 for Somerset.
Gregory was immensely impressive bowling at the death, cleaning up Will Gidman, Jack Taylor and David Payne with yorkers, while having James Fuller caught behind.
