Hampshire 316 for 5 (Dawson 100*, Smith 84) beat Glamorgan 130 (Berg 4-25, McLaren 4-42) by 186 runs
Scorecard

Liam Dawson smashed a 68-ball century and Glamorgan were then blown away with the ball to lose by 186 runs in Swansea. They slipped to 29 for 6 against the seam of swing of Gareth Berg and Ryan McLaren, the pair finishing with eight wickets between them to keep Hampshire's hopes of a Royal London quarter-final alive.

Forty runs came from the final two overs of Hampshire's innings, with Dawson reaching an unbeaten hundred by hitting the last ball of the innings, bowled by Michael Hogan, for six. Having been 70 from 61, he cleared the ropes four times in six deliveries at the death to record the second List A hundred of his career.

Glamorgan made a terrible start when David Lloyd was leg before to McLaren to the first ball of the innings and, despite the slow pitch, the Hampshire seamers repeatedly beat the bat, as Jacques Rudolph and Will Bragg edged balls to the wicketkeeper.

Colin Ingram, who struck hundreds in both one-day competitions against Essex last week, was the next to go when he top-edged a hook to fine leg. When Graham Wagg was leg-before to a perfect yorker from Berg, the home team, playing the first day of the festival at St Helen's, had lost five wickets for seven runs, with Berg taking 4 for 2 from 16 balls.

There were ironic cheers from the sizeable crowd in the 15th over when Mark Wallace became the first Glamorgan batsman to reach double-figures by driving Brad Wheal to the boundary. Craig Meschede top-scored with 45 and his partnership of 30 with Tim van der Gugten enabled Glamorgan to pass three figures, but it was little consolation for the home side or their supporters.

In complete contrast, Hampshire scored freely after winning the toss. Tom Alsop, who has struck a hundred and three fifties in the competition this season, made a fluent 35, before chipping Meschede to mid-on while Will Smith made the most of being dropped on 23 at midwicket off Andrew Salter to an anchor the innings with 84, putting on 61 with Joe Weatherley and 86 with Dawson to take Hampshire to 223 for 4 in the 43rd over. Dawson then hit the accelerator during a partnership of 60 in 34 balls with McLaren.

Dawson, captaining the side in the absence of Sean Ervine, said: "The win sets us up nicely for the final game against Somerset on Tuesday, and a chance to qualify for the quarter-finals. We were undecided what to do after winning the toss, but knowing the history of the Swansea ground, it was a good decision, as the pitch doesn't get any better in the second innings. We thought that around 270 would have been competitive, but to reach 316 was a massive bonus."
