New Zealand spinner Jeetan Patel starred with the ball once again as Warwickshire stepped up their challenge for the LV= County Championship title by beating Sussex by an innings and 43 runs at Edgbaston.
That ensured Patel finished with match figures of 10-163 and took his haul to 15 wickets in a back-to-back double over the south coast county in the space of three weeks.
Starting the last day 191 behind at 71-2 in their second innings, Sussex were skittled out for 219 despite half-centuries by Ed Joyce and Michael Yardy.
Chris Woakes claimed his 200th first-class wicket in 56 matches by trapping Joyce leg before for 74 and the England seamer also accounted for Andrew Hodd with an edge to third slip.
Patel then speeded up Warwickshire's progress to a fifth win in six games as he produced a decisive spell of 6-111 from the new pavilion end as Sussex - who have not won a championship game in Birmingham since 1982 - crumbled around captain Yardy.
Batting conservatively until hitting a couple of sixes, he stayed for three hours to make an unbeaten 62 but it was mostly a lone vigil as Patel turned up the pressure.
Having struck in his third over of the day when Murray Goodwin heaved a catch
to mid-wicket, he later dismissed Ollie Rayner and William Adkin, both snapped up in the close ring when prodding forward.
Rana Naved-ul-Hasan hoisted Patel to deep midwicket, Rikki Clarke nipped in to remove Monty Panesar and Patel had the final word when James Anyon shouldered arms after a stubborn last-wicket stand.
Murray Goodwin narrowly missed out on a century as Sussex struggled to halt their slide towards defeat against Warwickshire on day three at Edgbaston.
The visitors were propped up for more than four-and-a-half hours by Goodwin's defiant knock of 94, before eventually being dismissed for 259 in their first innings.
Sussex resumed on 103-3 but their middle order proved brittle, with New Zealand off-spinner Jeetan Patel taking the scalps of Andrew Hodd (15) and Olly Rayner (20).
Goodwin played well within himself and put on 54 with Will Adkin (29no) before he eventually pulled Chris Woakes (four for 67) to deep mid-wicket.
Sussex folded by mid-afternoon and forced to follow on, they then made 71-2, but still lie 262 behind the home side's first-innings total of 521.
Sussex will go into the final day trailing by 191 but with Ed Joyce perhaps offering some hope of an escape route - assuming he can build on his unbeaten 42 so far.
Sussex struggled to 103-3 by the end of day two at Edgbaston after Keith Barker's century helped Warwickshire amass 521 in their first innings.
All-rounder Barker made a carer-best 118 from number nine in the order as the home side's last four wickets added 329 runs.
The Bears had at one stage been struggling at 192-6 on the opening day but Tim Ambrose (73) and Chris Woakes (74) took their seventh-wicket stand to 127 before the latter fell to James Anyon.
Ambrose was run out with the score on 366 but Barker and Jeetan Patel, who made 65 from 77 deliveries, put on a further 155 for the ninth wicket - a record against Sussex.
The last two wickets both fell with the score on 521, Barker the last of them to go to seamer Anyon, who finished with figures of 5-136 from 34.1 overs.
Woakes followed up his efforts with the bat by removing Ed Joyce and Luke Wells and with Chris Nash also falling for 52 in off-spinner Patel's first over, Sussex closed still 418 runs behind.
Half-centuries from Will Porterfield and Laurie Evans helped Warwickshire reach 261-6 against Sussex by the close of day one at Edgbaston.
Ireland captain Porterfield and ex-Surrey batsman Evans shared a stand of 87 following the early departures of Varun Chopra and Ian Westwood.
James Anyon (3-69) removed both Warwickshire openers in his first spell and then also ended the third-wicket alliance when he had Porterfield caught by Michael Yardy for 66.
Evans fell soon after for 52, his first half-century for his new county, to Monty Panesar, who sent down 32 consecutive overs from the new pavilion end that included him picking up two further wickets.
Skipper Jim Troughton (26) was caught by Ed Joyce off the left-arm spinner and then the hosts lost Rikki Clarke for a 10-ball duck, leaving them teetering at 192-6.
However Tim Ambrose (44 not out) and Chris Woakes, who hit seven boundaries to race to an unbeaten 45, steadied the ship with a stand of 79.
