India have won through to the semi-finals of the women's World Twenty20 and will face Australia in Saint Lucia today. India advanced after a crushing 71 run victory over Sri Lanka in Saint Kitts on Monday. Batting first, they made 144 for three, with Sulakshana Naik (59) and Mithali Raj (52) both scoring fifties. Off-spinner Diana David then led the Indian attack with four wickets for 12 runs as Sri Lanka were held to 71 for nine from their 20 overs at Warner Park.
