Chris Jordan warmed up for the third Test with three wickets and on-loan James Tredwell took 4-7 as Sussex beat Warwickshire by 226 runs in the County Championship Division One clash at Horsham.
Set 326 to win in 77 overs, Warwickshire never recovered from Jordan's pre-lunch burst when he removed Varun Chopra, Will Porterfield and Jonathan Trott which reduced them to 9-3.
Tim Ambrose held up his former county with 56 but there was little support from his team-mates as they were routed for 99, an innings which featured five ducks.
Off-spinner Tredwell, who is in the second month of a loan spell from Kent, finished them off with four wickets, before the innings ended in farcical circumstances when Keith Barker was run out after being sent back by last man Boyd Rankin.
Jordan (3-38) had only bowled four overs in a T20 since the second Test against Sri Lanka five weeks ago and after taking two wickets in the first innings he produced a hostile burst of swing bowling to undermine Warwickshire's run chase.
Chopra (4) drove at a delivery he could have left alone in Jordan's second over and two balls later he had completed a double-wicket maiden when Porterfield was trapped lbw playing across the line for a duck.
The key wicket of Trott, who had made his first hundred of the season in the first innings, came four overs later when he edged a ball that beat him off the pitch.
There was a brief fightback by Ambrose and Ian Westwood, who took the score to 35 before left-armer Lewis Hatchett (1-26) got some extra bounce in his second over and Westwood (17) gave Brown his ninth catch of the match.
By then Tredwell was settling into a long spell and he struck twice in the 23rd over as Sam Hain was taken at short leg and Rikki Clarke at slip, both for ducks, to leave Warwickshire on 46-6.
Ambrose and Chris Woakes added 53 for the seventh wicket with Ambrose reaching his half-century with his seventh boundary, an on-drive off Steve Magoffin (0-18)
But Ambrose was bowled through the gate by Chris Nash (1-5) and in the last over before tea Tredwell switched ends and had Woakes (14) superbly caught one-handed by Jordan at slip.
After the interval, Tredwell bowled Jeetan Patel for a duck before the comical run-out of Barker (0) brought a sorry end to Warwickshire's batting display.
Earlier, Sussex had lost five wickets adding 41 runs before Ed Joyce declared his side's second innings at 245-9.
Patel picked up three of them to finish with 4-84 but Sussex were well on course to completing their first championship double over Warwickshire since 1960.
