Andrew Davies bowled Glamorgan to their opening Twenty20 Cup win of the season with victory over Somerset at Sophia Gardens by five wickets with four balls to spare.
Davies, awarded his county cap before the match, produced Glamorgan's most economical four-over spell in the competition - two for 12 - to restrict Somerset to 142 for eight.
And though Glamorgan stuttered to their target Mark Wallace and man of the match Ben Wright took the Welsh county home in the last over and condemned Somerset to their third straight defeat.
The sixth-wicket pair added 47 in six overs with Wright's 28 coming off 17 balls.
Davies struck with the ninth ball of the contest to have Justin Langer caught at slip by Tom Maynard to leave Somerset 11 for one.
The Glamorgan seamer helped to contain Somerset to 29 for one after six overs, going for only nine runs from his first three overs. That after home captain David Hemp had won the toss.
But Marcus Trescothick and Matthew Wood got into their stride taking 22 off the next two overs, each hitting a six.
Trescothick proceeded to take 16 off the first four balls of an Alex Wharf over before being bowled via an inside edge as Somerset reached 68 for two in the ninth over.
Glamorgan made further inroads through Ryan Watkins who had both Cameron White and Wood, who provided a run-a-ball 39, caught at extra cover as Somerset were reduced to 95 for four in the 14th over.
Watkins was in the action again to catch Craig Kieswetter on the long-off boundary off Dean Cosker, who next ball dismissed James Hildreth caught behind attempting a reverse sweep.
A conventional sweep unseated Peter Trego, who was caught on the midwicket boundary to give Cosker his third victim, while Will Durston became Davies's second victim well caught by Hemp running back at midwicket.
Glamorgan made steady progress in reply but like Somerset lost wickets at regular intervals with new ball bowlers Trego and Andrew Caddick reducing the home side to 57 for three and then 96 for five before Wallace and Wright turned the match Glamorgan's way.
