Somerset got their first victory of the season as Craig Kieswetter's century and a quickfire 94 from Jos Buttler set up a 47-run success over Nottinghamshire in the opening round of the Clydesdale Bank 40.
Having lost their opening two Championship matches by innings margins, the Cidermen were sent in at Trent Bridge as the home side looked to prey on their misfiring batting line-up.
And it looked to be working when Somerset lost skipper Marcus Trescothick lbw for a three-ball duck in Luke Fletcher's opening over.
But Kieswetter and Peter Trego counter-attacked impressively during a second-wicket stand of 100 in 15.3 overs.
Trego's departure, bowled by Samit Patel for 47 off 40 balls, was the start of a collapse from 100-1 to 149-4.
Kieswetter, however, advanced to his hundred from 110 deliveries with eight fours and two sixes.
He was out immediately after reaching the landmark but that left the stage free for Buttler to produce an incredible display of boundary hitting.
The 20-year-old dispatched 13 fours and two sixes to finish with 94 not out from 56 balls, powering Somerset - who were runners up in all three competitions this season - up to a final score of 270-5.
Nottinghamshire were never in the hunt after slipping to 78-4 in the 14th over of their reply.
And Sri Lankan spinner Ajantha Mendis ran through the tail for figures of 4-35 as the Outlaws were dismissed for 223 in 36 overs.
