Hampshire 331 for 8 (Vince 190, Dawson 73) beat Gloucestershire 246 (Crane 3-64) by 71 runs (DLS mehod)
James Vince produced the highest one-day score in England for over a decade with an incredible 190 as Hampshire remained unbeaten in the Royal London Cup with victory over Gloucestershire.
No player had scored as many since Ravi Bopara for Essex in 2008, but Vince crashed the highest individual total for a Hampshire player in List A cricket - beating his own previous best of 178. The innings was even more special for the situation, having arrived at the crease in the second over before Hampshire were reduced to 65 for 4 and struggling.
Vince put on a record 186-run stand for the fifth wicket with Liam Dawson and guided his side to 331 before Hampshire bowled Gloucestershire out for 246 to complete a 71-run victory by the DLS method.
Hampshire were put in on a good-quality wicket, with variable conditions throughout the match, and initially struggled, with Chris Liddle the chief destroyer with the ball.
David Payne was the first to strike as Tom Alsop attempted an extravagant drive in the second over and was bowled through the gate. Fast bowler Liddle then entered to find Aiden Markram edging behind before forcing Sam Northeast and Rilee Rossouw to chop onto their own stumps.
Enter Dawson, to accompany, and save the innings with Vince. Both carefully negotiated the niggling line and length of the Gloucestershire attack before fluently moving to fifties, both from 63 balls.
Together they added 186 runs to steam Hampshire into a strong position, before Dawson fell for 73 as he picked out Benny Howell at long-on to hand Liddle figures of 4 for 66.
Vince has now passed fifty in three of his four one-day innings this summer - and given the England selectors a push ahead of the World Cup this summer if any of the currently selected players suffers an injury.
This was must-watch cricket as he moved through the gears and struck five huge sixes - the pick of which saw him dance down the wicket and deposit a checked cover driver over the off-side. He reached 100 in 111 balls, 150 in 138 as he rattled his total from 100 to 190 in 43 deliveries.
Vince's assault saw his side score 114 runs in the last 10 overs, although James Fuller's handy 21 off 13, which included the biggest maximum of the day over squad leg, helped the cause.
Vince eventually succumbed for 190 before scooping to Tom Smith at point and was given a rapturous reception from the Ageas Bowl members.
With DLS altering the target to 318 off 47 overs, Kyle Abbott stunted Gloucestershire's reply by dismissing George Hankins in the third over, caught at point by Northeast, and then Gareth Roderick, caught and bowled. Captain Chris Dent was then run out by Northeast's direct hit, as the visitors slumped to 38 for 3.
Mason Crane, who posted 3 for 64, had James Bracey caught by a stunning outfield catch by Dawson, before Howell was lbw to the leg-spinner.
Jack Taylor was bowled by Crane, before Dawson had Graeme van Buuren stumped and Smith castled to complete figures of 2 for 32. Brad Wheal bowled Ryan Higgins, before Hampshire were held up by a 50-run stand for the last wicket between Payne and Liddle, eventually completing their victory with 19 balls to spare.
