Left-arm spinner Rangana Herath has claimed his maiden 10-wicket match haul to steer Sri Lanka to an emphatic 75-run win in the first Test against England in Galle.

The tourists, chasing a target of 340 runs, were bowled out for 264 in their second innings after tea on the fourth day despite Jonathan Trott’s defiant century threatening to steal the game.

Herath claimed six wickets in each innings against the world’s No.1 Test side, while off-spinner Suraj Randiv took four second-innings wickets.

England’s reply revolved around Trott’s 112, but the tourists lost their last five wickets for 12 runs after being in a strong position at 4-233 during the middle session.

Trott hit 10 boundaries in his seventh Test century when he flicked Randiv (4-74) and was snapped up by a diving Tillakaratne Dilshan at backward short-leg.

Wicketkeeper Matt Prior helped Trott add 81 for the fifth wicket before he was dismissed by Herath (6-97) for 41 as Lahiru Thirimanne clung on to a full-blooded sweep at forward short-leg.

Debutant Samit Patel made nine when his uppish drive off Herath was caught by Dilshan at short cover.

England, who will slip to number two behind South Africa if they lose the two-Test series, lost Kevin Pietersen in the day’s third over after just seven runs had been added to the overnight score of 2-111.

Pietersen, on 30, attempted to on-drive spinner Randiv and only managed to spoon an easy catch to Sri Lankan captain Mahela Jayawardene at short mid-wicket.

The sloppy dismissal ended a valuable 70-run partnership for the third wicket with Trott after England had been reduced to 48-2 late on Wednesday afternoon.

Accurate Sri Lanka bowling tied down the tourists to just 34 runs from 15 overs in the first hour of play, 22 of them coming from the bat of Trott.

Bell, who top-scored with 52 in the first innings, missed a sweep shot off Herath and was given out leg-before by umpire Rod Tucker.

Bell immediately asked for a review, but he did not earn a reprieve from TV umpire Bruce Oxenford and England slipped to 4-152.

England played positively after lunch, scoring 51 runs from 15 overs as Sri Lanka handed Herath the new ball that was claimed as soon as it was due in the 81st over.

The second and final Test will start at the P. Sara Oval in Colombo from April 3.
