Sussex’s hopes of maintaining their 100% start to the new season were dented by a century from Marcus Trescothick on the second day of their County Championship clash with Somerset at Hove.
Trescothick made 115 and put on 139 with Alviro Peterson (76) as Somerset made 372 in their first innings after resuming on 83-3 overnight.
Chris Jordan wrapped up the Somerset innings to finish with figures of 5-76 before Sussex closed on 25-1 in response.
The morning had belonged to Somerset as Trescothick and Petersen put the visitors in a position of strength after Jordan had trapped night-watchman Alfonso Thomas for four.
It could have been different, however, if Sussex had held their catches with Petersen being dropped on seven and 29 while Trescothick was put down on 65.
They made Sussex pay with Trescothick reaching the 52nd first class century of his career – and his first since September 2012 - off 214 balls.
Petersen’s hopes of reaching three figures were dashed when he was well stumped by Ben Brown off the bowling of Ashar Zaidi.
The arrival of the new ball and the return of Steve Magoffin and Jordan to the attack brought a flurry of wickets as the momentum swung.
Magoffin bowled Trescothick off an inside edge, James Hildreth edged Jordan to Ed Joyce at third slip and Craig Kieswetter fell in identical fashion off the bowling of Jon Lewis.
A last wicket partnership of 75 between Lewis Gregory (47) and Johann Myburgh (37 not out) meant it was definitely Somerset’s day.
Gregory’s entertaining innings came to an end when he was caught on the boundary trying to bring up his half century to give Jordan the seventh five-wicket haul of his first class career.
Sussex were left to negotiate a difficult 11 over spell with the bat before the close and lost in-form skipper Joyce.
Joyce was unable to carry on from his two centuries in the last match at Edgbaston as he edged a short ball from Thomas to the wicketkeeper for six but Luke Wells (5) and Mike Yardy (14) stood firm to ensure there was no further damage.
