Unorthodox Sri Lanka spinner Ajantha Mendis insisted on Thursday ahead of the World Twenty20 semi-final with the West Indies that "no batsman has figured me out yet".

Mendis has taken 10 wickets at 10 runs apiece during Sri Lanka's unbeaten run to the last four and, three months to the day after he was discharged from a Colombo hospital post the Lahore attacks, returned figures of three for nine against New Zealand in a 48-run Super Eights win at Trent Bridge on Tuesday.
