NOTTINGHAM : Ajantha Mendis spun out New Zealand as Sri Lanka roared into the World Twenty20 semi-finals with an emphatic 48-run win at Trent Bridge here today. The mystery spinner grabbed 3-9 as the Black Caps failed miserably to chase down a target of 159 in a must-win game and were shot out for 110 in 17 overs. Martin Guptill top-scored with 43, but New Zealand lost their last eight wickets for 46 runs after being comfortably placed at 64-2 in eight overs. Sri Lanka topped group F with three straight wins, following their all-win record in the preliminary league. Pakistan take the second spot in the group with four points, two more than New Zealand. Sri Lanka’s gamble to give the second over to spinner Sanath Jayasuriya backfired as Aaron Redmond smashed the left-armer for three consecutive boundaries and a six. Redmond, however, failed to survive Lasith Malinga’s first over, the fifth of the innings, when he misjudged a slower ball and tapped an easy catch to mid-wicket. New Zealand moved to 64-2 when Mendis turned the game around with two wickets in four balls, having Ross Taylor stumped before bowling Scott Styris. Another two wickets fell for as many runs when Isuru Udana bowled Jacob Oram and Jayasuriya had Guptill caught on the square-leg fence by Angelo Mathews. Sri Lanka continued to strike at regular intervals to wrap up the match with three overs to spare. Earlier, Sangakkara made 35 to anchor his side to 158-5. Sangakkara put on 62 in 49 balls for the third wicket with Tillekaratne Dilshan and 50 for the fourth with Mahela Jayawardene. Dilshan hit a pugnacious 48 off 37 balls. Vettori also removed Sangakkara in the 18th over to a catch in the deep to finish with 2-32. Jayawardene remained unbeaten on 41 off 29 balls. Sri Lanka took a heavy toll of fast bowler Kyle Mills, who went for 41. New Zealand removed opener Jayasuriya and Chamara Silva by the fourth over to make it 25-2, before Dilshan and Sangakkara began the rescue act. Windies qualify London: Ramnaresh Sarwan and Shivnarine Chanderpaul steered the West Indies into the semi-finals of the World Twenty20 at England’s expense as they beat the hosts by five wickets on the Duckworth/Lewis method here on Monday. West Indies, set a revised target of 80 in nine overs after rain delayed the start of the second innings, finished on 82-5 with four balls to spare. Sarwan was 19 not out and Chanderpaul 17 not out, their unbroken stand of 37 after West Indies were wobbling at 45-5 in the sixth over.
