Matt Prior inspired a Sussex fightback by equalling the record for the most dismissals in an innings against champions Warwickshire on day two of their LV=Championship game at Hove.
The England wicketkeeper became the ninth Sussex player to claim six dismissals in an innings after his full-length dive helped remove last man Boyd Rankin as the Midlanders were dismissed for 453.
Chris Jordan also enjoyed a good day as he removed Jonathan Trott - when he was four short of his hundred - and Tim Ambrose to finish with figures of 4-73 to take his season's tally to 17 wickets.
In reply, the hosts reached 129-1 at stumps, but the slow pitch may thwart both sides' hopes of a victory.
Openers Chris Nash and Luke Wells looked relatively untroubled when they began the hosts' response, adding 108 in 39 overs for the first wicket.
But Warwickshire made the breakthrough when Nash, on 43, edged low to second slip and the ball deflected off the boot of Will Porterfield and into the hands of Varun Chopra at first slip.
Left-hander Wells was undefeated on 76 as Sussex got to the close with no further loss - trailing by 324.
Trott had added nine runs to his overnight score when he edged a ball to slip from Jordan's bowling and his next over he again found bounce and seam movement to undo Ambrose for a duck.
Although Monty Panesar belatedly picked up a wicket when Laurie Evans was bowled sweeping, Warwickshire regained control in an eighth-wicket stand of 103 between England prospect Chris Woakes and Tom Milnes (42).
Woakes went for quick runs and was bowled by Panesar slogging across the line (72) before James Anyon ended the innings with the wicket of Rankin - his third of the innings against his former county.
