A blistering knock from Aneurin Donald and two wickets for Chris Morris wasn't enough as Hampshire suffered a seven-wicket defeat against Gloucestershire at Bristol.
Gloucestershire's James Bracey registered his highest score in Vitality T20 Blast cricket as the hosts successfully chased a victory target of 140 with 13 balls to spare at the Bristol County Ground.
Bracey scored his maiden T20 fifty in his ninth appearance and dominated a match-winning partnership of 102 in 11 overs with Michael Klinger on his way to a superb 64 from 48 balls.
Donald hit a rapid 44, but Hampshire stumbled to 139-6 in the face of incisive bowling from left arm seamer Chris Liddle.
Without a meaningful score to his name so far this summer, Klinger enjoyed a slice of good fortune when Ryan Stevenson, bowling the fifth over from the Ashley Down Road End, apparently located his outside edge, Lewis McManus held on behind the stumps and umpire Mike Burns gave the Australian the benefit of the doubt.
The effects of the floodlights and gathering dew combined to speed up the ball and Bracey and Klinger took full advantage, the former going to 50 via his eighth four.
Having raised 40 from 38 balls and hit two sixes, Klinger succumbed to Liam Dawson, while Bracey departed soon afterwards, caught and bowled by Chris Morris. That left Ian Cockbain and Ryan Higgins to complete the chase and complete a comfortable victory.
The home-side had first to weather a terrible storm, opener Donald clubbing a quickfire 44 from 23 balls. He struck five fours and two sixes as the powerplay yielded dividends for Hampshire and Gloucestershire, who bowled too short initially, no doubt breathed a collective sigh of relief when the Welshman became the first of Chris Liddle's three wickets.
The complexion of the contest underwent a fundamental change when Sam Northeast and Liam Dawson then departed in the space of eight deliveries in the 12th and 13th overs.
Morris (18 not out) and Lewis McManus (18) went someway towards rebuilding in difficult conditions, staging a partnership of 28 in three overs. But when Tye had McManus caught at square leg off a top-edged pull shot in the penultimate over, Hampshire were 135-6.
