Hampshire 293 for 3 (Alsop 130*, Vince 95) beat Glamorgan 292 for 9 (Lloyd 68, Wagg 68, Abbott 3-47) by seven wickets
Tom Alsop's smashed his one-day career best to help Hampshire continue their 100% record in the Royal London Cup as they thrashed Glamorgan by seven wickets. Holders Hampshire sailed past Kent earlier in the week and had few worries in seeing off winless Glamorgan with 8.1 overs to spare.
Alsop and captain James Vince were the catalysts for the victory with a 161-run stand for the second wicket - with Alsop ending on a classy unbeaten 130 and Vince falling five runs short of three figures.
On a good-paced wicket under blue skies, Hampshire lost Aiden Markram in the ninth over when he thumped to Billy Root at deep square leg. But Vince and Alsop put Glamorgan to the sword with their crushing partnership.
Vince, on the back of a half-century in the competition opener against Kent on Wednesday, continued his form in a typically attractive style. Instead of his usual off-side bias, Vince hit eight of his 11 fours through the leg side, with some powerful, yet perfectly placed, shots clubbed between midwicket and square leg.
The skipper reached his fifty in 43 balls and looked set for a ninth List A ton, but picked out Craig Meschede at point on 95.
But it was Alsop who sparkled. He was the more watchful early on, not scared to soak up pressure but relieving it by dispatching boundaries when needed, including two huge sixes.
The former England Lions batsman scored 72 in last summer's final and picked up where he left off as he collected his second century in the format, and his first for two years, in 93 balls. Sam Northeast fell for 14 when he was lbw to Marnus Labuschagne but Alsop continued his raid with another six fours and a maximum to take Hampshire home.
Glamorgan's innings was a curious one, having won the toss and elected to bat, with two collapses but managing to reach a creditable total.
Kyle Abbott was the instigator of the first wobble of the innings as he restricted the visitors to 28 for 3 in the first eight overs with high-quality line-and-length bowling.
Meschede was the first to depart when his attempted hook was top-edged into the gloves of Alsop. Charles Hemphrey and Labuschagne were also early victims - both caught off edges, the former to Liam Dawson at first slip, the latter to Alsop.
Just as Glamorgan appeared to be faltering towards a low total David Lloyd and Billy Root steadied things by adding 100 for the fourth wicket - helped by Abbott and the equally efficient Chris Wood being withdrawn from the attack.
Lloyd was the more attacking of the duo and reached his fourth List A half-century with a six to the longest square boundary off James Fuller. But another dip saw them fall to 140 for 6.
Root reached 39 before he was bowled by part-time spinner Markram and Lloyd's entertaining knock was ended by a run out. Kiran Carlson was then lbw to Mason Crane but Glamorgan's tail wagged, through Graham Wagg.
Veteran Wagg took control, carting Dawson for a pair of maximums in an over on his way to a 47-ball fifty. Chris Cooke was given a life when he was dropped by Fuller at point and added 95 with Wagg to take their side over 200.
Cooke, run out by a stunning swoop by Vince at cover, and Wagg, caught for a career-best 68 slapping to Vince off Dawson, departed within an over of each other, before Marchant de Lange was stumped.
