Chasing 261 runs, India were 147 for the loss of 3 wickets in 29 overs against Australia in their quarterfinal match of the ICC cricket World Cup at Motera in Ahmedabad when the report last came in.Earlier, Australian skipper Ricky Ponting won the toss and elected to bat. Australian had a very cautious start after losing their opener Shane Watson cheaply. But Captain Ricky Ponting marked his return to form with a scintillating century as Australia posted a competitive 260 for six in stipulated 50 overs. It was Ponting who came to rescue the team and scored a splendid 104, followed by Brad Haddin 53 runs. Ponting notched up his 30th ODI century and his 5th in the World Cup to silence his detractors.For India, Zahir Khan, Yuvraj Singh and Ashwin claimed two wickets each. The winner of today's match will play Pakistan in the second semi-final match, slated for 30th of March in Mohali.
