Sean Ervine's 46 from 28 balls helped Hampshire seal their third Twenty20 Cup win of 2008 against Surrey.
Surrey had won the toss and elected to bat, with a blistering 90-run stand between Mark Ramprakash (60) and Abdur Razzaq (65) helping them to 175-6.
Confident knocks from Michael Lumb (45) and Mike Carberry (45) gave Hampshire the ideal start.
And late hitting from Ervine and Greg Lamb (22) eased the Hawks to 177-6 to claim a four-wicket win at The Oval.
Surrey recovered from a faltering start after losing openers Ali Brown (0) and Scott Newman (15), with Ramprakash and Razzaq leading the way.
Ramprakash smashed three sixes in his 43-ball knock, while Pakistan all-rounder Razzaq went two better with five maximums from just 37 balls.
Fast bowler Nantie Hayward collected two wickets, along with Ian Harvey, whose two dismissals in the final Surrey over proved to be crucial.
Hampshire lost opener Harvey in the second over, but Lumb and Carberry steadied the innings with a 48-run second-wicket partnership.
Lumb became the first of Saqlain Mushtaq's three wickets when he was bowled in the former Pakistan off-spinner's opening over.
Carberry soon followed when he was stumped off Chris Schofield, but Ervine maintained Hampshire's momentum, helped by Lamb's 16-ball knock to clinch the win.
