Glamorgan 175 for 3 (Karlson 109) beat Somerset 171 for 9 (Banton 59, McAndrew 4-15) by seven wickets

Kiran Carlson's magnificent 42-ball century gave Glamorgan their first win of the Vitality Blast against Somerset at Sophia Gardens.

The Glamorgan captain gave bowlers déjà vu from his only other T20 century when he struck 135 in a record-breaking win against the west country side in Cardiff two years ago. On this occasion, Carlson finished on 109 to steer Glamorgan home by seven wickets.

Carlson rode his luck early on but took advantage of a new look Glamorgan side as Jimmy Neesham was also given a debut for a seventh individual county against an injury-hampered, previously unbeaten Somerset side.

Debutant Nathan McAndrew and leg-spinner Mason Crane also supported the win for his new county, taking 4 for 15 and 3 for 42 respectively, to counter a destructive innings from Tom Banton (59 off 25).

Banton got off to a flying start to give Somerset a productive powerplay. Things weren't always going Glamorgan's way either - Josh Thomas' first T20 for Somerset started with an outside edge for four against the off-spin of Ben Kellaway in the first over.

McAndrew striking in the fifth halted proceedings momentarily but when Crane was introduced, Banton reached a 21-ball 50 with a six first ball of the seventh, followed by another.

Banton's dismissal before further damage could be done was crucial as Rew brothers James and Thomas, Tom Abell, and Daniel Sams all made starts but were unable to carry on at his pace.

From 100 for 2 at the halfway stage, Glamorgan fought back with frequent single-digit overs, McAndrew finishing strong with two wickets at the death.

In reply, Carlson's magnificence wasn't necessarily obvious from the off, although the scorecard would suggest so. Eighteen of the captain's first 33 runs in just 16 balls came from edges in the powerplay with a short-third and fine-leg both operating in the circle.

Will Smale's first delivery flicked to fine leg for four was a much prettier sight than his attempted ramp last time out which saw him removed first ball on that occasion.

Like Banton, Carlson brought up his 50, then the century with a six off Lewis Goldsworthy and Josh Shaw respectively. Somerset would rue missing a direct hit when the centurion was on just 14 taking a single to mid-on.

A flurry of wickets left Sean Dickson to haunt his former side with the winning runs to get the Welsh county home against the defending champions.
