Somerset 114 for 1 and 213 v Sussex 177

Marcus Trescothick scored his second half-century of the match to put Somerset firmly in control against Sussex at Hove - while there was an injury scare for England wicketkeeper Matt Prior. The visitors established a lead of 150 runs with nine second-innings wickets in hand in the County Championship Division One tussle.

Somerset's increasingly commanding position came despite the efforts of James Anyon, who hit his first first-class fifty after Sussex had lost six wickets for 24 runs in six overs after lunch, including that of Prior who was struck on the elbow.

Sussex, replying to Somerset's first innings of 213, made a poor start with Chris Nash edging the fourth ball from Charl Willoughby to Trescothick at second slip and Luke Wells going the same way in Willoughby's third over.

Ed Joyce and Murray Goodwin got Sussex back on an even keel by taking them to 71 for 2 but then they fell apart. Joyce was caught behind for 29 off the second ball after lunch from Steve Kirby, and Goodwin, driving, edged the last delivery of the over to Trescothick at second slip and was gone for 26.

Pete Trego struck twice in the next over, Prior chipping his third ball tamely to Alex Barrow at midwicket and Andy Hodd snicking his second ball to Arul Suppiah at first slip. Mike Yardy was the next to go, giving Trescothick his fourth catch at second slip off Trego, and although Rana Naved-ul-Hasan flicked Trego for six and took two fours off Kirby, he soon fell lbw to Kirby for 20.

Sussex had collapsed to 95 for 8 before Monty Panesar and Anyon began to show that the conditions were not so bad. Panesar was as dogged as he had been for England against Australia at Cardiff in 2009 while Anyon, boasting a batting average of four this season, played the innings of his life.

They had put on 50 in 20 overs when Anyon drove Kirby straight to Trego at mid-off and Panesar, slow to respond to the call for a single, was run out for 14 by a direct hit. Undeterred, number 10 Anyon went on to play like a proper batsman, hitting nine fours, three of them in the same over from Lewis Gregory to take him to his fifty off 78 balls. He faced only three more before slicing Trego, who finished with 4 for 24, to cover - to be out for 51.

Prior, who had been struck on the elbow by the first ball he received from Kirby, did not keep wicket when Somerset went in again 36 runs ahead.

However Mark Robinson, the Sussex coach, said it was purely a precautionary measure and he was only badly bruised. That indicated there should be no doubt about Prior's availability for England ahead of next week's first Test against Sri Lanka.

Sussex had more to worry about as Trescothick and Arul Suppiah put on 102 before Suppiah was stumped off Panesar for 38. Trescothick went on to finish unbeaten on 64, including nine fours and a six, as Somerset closed on 114 for 1.
