COUNTY CHAMPIONSHIP DIVISION TWO, Guildford:
CLOSE OF PLAY, DAY ONE: Sussex 217, Surrey 47-0
Surrey 3pts, Sussex 1pt
Tremlett joined Surrey from Hampshire at the end of last season
Chris Tremlett took his best bowling figures for Surrey as Division Two leaders Sussex were dismissed for 217 on day one at Guildford.
Tremlett took 4-32 and Gareth Batty 3-81, as the visitors initially slumped to 101-7.
Sussex were rescued by Ollie Rayner's 47 and 45 from William Adkin on his first-class debut, while Monty Panesar ended unbeaten on 20.
Surrey reached the close on 47-0, a deficit of 170 runs.
Openers Tom Lancefield (20 not out) and Arun Harinath (19 not out) negotiated 17 overs to the close without any problems.
Earlier, Tremlett, who is playing in his 100th first-class match, looked dangerous from the start, and took the wicket of Ed Joyce, who edged to slip from the second ball of the day.
Tremlett uprooted Michael Thornely's off-stump in his second over, as the Sussex number three fatally shouldered arms, and he picked up his third wicket two balls later when Murray Goodwin was lbw, although there was more than a hint that the batsman had got an inside edge onto his pads.
Batty picked up two wickets in the 16th over as Chris Nash padded up and was caught at short leg and two balls later skipper Mike Yardy drove a ball tossed up to short extra-cover.
Sussex were in trouble on 47-5, but went to lunch on 91-6 as Yasir Arafat and Ben Brown added 40, before Brown fell leg before to Jade Dernbach in the last over before the interval.
Arafat top-edged a sweep to give Batty his third wicket after lunch and debutant Adkin needed 29 balls before he got off the mark with a boundary.
From then on he visibly grew in confidence and put on 59 in 20 overs with Rayner to push Sussex towards 200.
Rayner was three runs short of a well-deserved half-century when Batty took a stunning catch on the mid-wicket boundary, keeping his feet just inside the rope to intercept a full-blooded slog sweep.
Adkin and Monty Panesar continued the recovery by adding 41 for the ninth wicket and earning their side an unexpected batting point.
Adkin, who faced 139 balls and hit seven fours, eventually gloved a lifter to slip as Tremlett took his fourth wicket and the innings ended in spectacular fashion with off and middle stumps out of the ground as Corey Collymore was yorked by Stuart Meaker.
