India were knocked out of the Women’s T20 World Cup after Australia’s Ellyse Perry and Ashleigh Gardner struck half-centuries to secure a six-wicket win at Lord’s on Sunday. Australia maintained their flawless record in the group stage, winning all five matches to finish top and advance to the semi-finals, chasing down India’s target of 171 with an over to spare. India had entered the match needing a victory to progress after South Africa boosted their own qualification chances with a four-wicket win over Bangladesh in a low-scoring game.
