Sri Lankan players celebrate a West Indies wicket during their 2nd Test at Galle on Friday. GALLE: Spinners Lasith Embuldeniya and Ramesh Mendis took all 10 wickets as Sri Lanka demolished the West Indies to win the second Test in Galle on Friday with a session to spare.Chasing an improbable target of 297 to secure their maiden Test win on the island, the visitors lost only two wickets in the first session and looked determined to save the Test match.But in a sensational collapse, they lost eight wickets for 40 runs after lunch to leave them all out for 132 and hand the hosts a 164-run victory. Not a single batsman managed a half-century in the second innings with Nkrumah Bonner’s 44 being the highest. Off-spinner Ramesh Mendis triggered the collapse when he claimed three wickets in an over in the afternoon session. He started off by breaking the 27-run third wicket partnership between Nkrumah Bonner and Shai Hope when Hope clipped one straight to Suranga Lakmal at square leg. Then Roston Chase was superbly caught by Osada Fernando at short leg. Kyle Mayers survived the hat-trick ball but four balls later edged one to Dhananjaya de Silva at first slip. It was a first 10 wicket Test for Mendis after he claimed career-best figures of six for 70 in the first innings. He has been the main tormentor for West Indies with 18 wickets in the series.Playing just his fourth Test match, the 26-year-old Mendis has been a real find for Sri Lanka, bowling long spells and becoming his captain’s most trusted bowler. Mendis finished with a match bag of 11 wickets and was named Player of the Series, while Dhananjaya de Silva — who hit an unbeaten 155 in Sri Lanka’s second innings — was declared the Man of the Match. Mendis was well supported by left-arm orthodox spinner Lasith Embuldeniya, who also finished with a five wicket haul in the second innings — his fifth in Test cricket. Embuldeniya dismissed Jermaine Blackwood in the last over before lunch and then came back to polish off the tail as West Indies’ troubles with spin continued. Sri Lanka retained the Sobers-Tissera Trophy and moved up to seventh in the ICC Test rankings, with West Indies slipping to eighth. West Indies captain Kraigg Brathwaite was disappointed with the result but sought to single out positives for his side. Sri Lanka also collected 24 points on offer in the ICC Test Championship by winning both games. They had won the first Test by 187 runs.
