Steve Magoffin and James Anyon both took four wickets as Sussex bowled Surrey out for just 124 on the opening day of their County Championship clash at Horsham.
Magoffin took 4-27 and Anyon 4-63 to justify skipper Mike Yardy's decision to bat first after winning the toss.
Naved Arif chipped in with two wickets as Surrey were dismissed inside 41 overs, Gareth Batty providing the only real resistance with 32.
Sussex made a solid start in reply after losing Ed Joyce for just eight with Chris Nash and Luke Wells adding 69 for the second wicket.
Nash was dismissed for 38 just before rain stopped play after tea but Wells, who was recalled to the side in place of Murray Goodwin, finished unbeaten on 33.
