Scorecard
James Vince notched his maiden LV= County Championship century of the season before the bowlers lead Hampshire well on the way to a crushing victory at the Ageas Bowl. Captain Vince amassed 1525 runs last season and seemed on the brink of an international call-up but bar three figures in a university match he has struggled in red ball cricket.
His ton was followed up by a team effort with the ball as Liam Dawson and Fidel Edwards both snatched two each with Hampshire needing four wickets on the final day for their maiden home win of the season.
Vince, with batting partner Michael Carberry, began the day as they ended the previous in glorious touch - the pair amassing 180 for the second wicket. Both went past 50, Vince in 105 balls and Carberry in 120 deliveries - with the former smashing a six over midwicket - as the hosts scored quickly.
The partnership was ended out of nowhere when England and Ireland international Boyd Rankin found an edge before Tim Ambrose pulled off an eye-catching catch behind - Carberry departing for 91, his second dismissal in the 90s this season. Will Smith came and west for two before lunch with a loose cut shot - another bowled Rankin, caught Ambrose.
After lunch, Vince reached his lavish century from 170 balls - which included 11 fours and a six. Vince and Gatting scored quickly putting on 79 runs in 9.5 overs before the former called the sides off to give Warwickshire almost five sessions to either chase 444 or find a draw.
And the quest to avoid defeat started badly when Varun Chopra was leg before to a Gareth Berg ball which nipped back and stayed low. Laurie Evans was then bowled by Jackson Bird - the ball pinging back the batsman's off peg for a duck - and Jonathan Trott's continued a horrendous week against Hampshire by departing lbw for 5. Wickets continued as Sam Hain was leg before to first innings star Edwards.
Ian Westwood provided a minuscule of personal delight with his fourth fifty of the season - from 108 balls - but the next ball he looped a push to Will Smith at short leg. Former Test duo Tim Ambrose and Rikki Clarke delivered some resistance in the twilight with a sixth wicket stand of 64.
Clarke became the second Warwickshire player to reach 50 in the match, coming in 55 balls, and brought up with a clanging pull in front of square. Wicketkeeper Ambrose prodded to Vince at first slip off the West Indian Edwards - as he ended the day with figures of 2 for 25, Dawson 2 for 34.
