Gloucestershire 164 for 2 (Hammond 51, Klinger 46) beat Kent 160 for 5 (Denly 99*) by eight wickets
Miles Hammond's quickfire first T20 fifty and an unbeaten 32 from Ian Cockbain eased Gloucestershire to their sixth Vitality Blast victory of the season in a top-of-the-table clash with Kent at Canterbury.
There was also a typically calm and responsible 43-ball 46 from their captain Michael Klinger as Gloucestershire chased down Kent 160 for 5, in which Joe Denly played an almost lone hand with a superb 99 not out from 63 balls, with five sixes and seven fours.
Benny Howell, too, played his part by following up his 2 for 29 with 20 not out from 13 balls, including the winning four struck over mid-off from the second ball of the final over, bowled by Adam Milne, with the scores level.
Left-hander Hammond had scored 51, with three sixes and five fours, when he hit the 31st ball he faced, the first of Calum Haggett's second over, to wide deep midwicket to end an opening stand of 76 with Klinger.
Hammond uppercut Haggett for a remarkable six over cover point in the third over, and then also clubbed leg spinner Denly and seamer Ivan Thomas for sixes.
Klinger, content to play a supporting role, nevertheless seized on a high full toss from left-arm spinner Imran Qayyum at the start of the 11th over to smash a six over long leg. The over, which also contained five wides when Qayyum speared a ball down the leg side, ended up costing 18 runs and left Gloucestershire requiring just another 57 from the last nine overs.
To their credit, Kent's bowlers made the visitors work hard for the win, with Klinger departing in the 16th over when he tried to reverse-hit Qayyum but could only pick out Denly at backward point.
Cockbain and Howell held their nerve, however, and the result was never in doubt once they had plundered 18 from the 18th over, bowled by Marcus Stoinis until he went off injured after bowling five balls, leaving Qayyum to finish it.
A six by Cockbain over midwicket was followed by Howell driving a powerful four and then taking another four, through backward point, from Qayyum's final ball.
Kent reached 50 without loss in the six-over Powerplay, with Denly the initial aggressor with square cut and lofted off-side fours in the third over, bowled by Matt Taylor, and a six swung over wide midwicket against David Payne.
Daniel Bell-Drummond, starved of much of the early strike, got going in the sixth over by pulling Taylor for six and then lofting the next ball over mid-off for four. On 19, however, he was perhaps unfortunate that a thigh-high full toss from Benny Howell was not called as a no ball as he mis-hit to deep midwicket.
At halfway Kent were 84 for 1, with Denly hoisting Howell for six in his second over, and Heino Kuhn contributed a brisk 18 before being bowled sweeping at Graeme van Buuren's left-arm spin in the 11th over.
Successive sixes by Denly off van Buuren in the 13th over, the first straight and the second over the head of the long on fielder, provided Kent with some much-needed acceleration but Sam Billings found it hard to get going and it was no surprise when, on 7, he hit his 13th ball straight to long-on to give Howell his 100th T20 wicket.
Stoinis offered one meaty blow, a lofted four off his fellow Australian AJ Tye, before hitting the same bowler to long off where Howell ran to his left to hold a good catch.
Denly finished that same over by driving Tye wide of Howell for six but at the start of the next over Alex Blake was leg-before for a first ball duck trying to work David Payne to midwicket and the only boundary conceded by Payne and Tye in the last two overs came from the final ball of the innings, which Denly crashed through square cover to end up a frustrating one run short of a fifth T20 century.
