(CNN) -- Australian captain Ricky Ponting made a gallant 72 as Australia defied India on the fourth day of the second Test match in Bangalore on Tuesday.
Ponting, who also scored a half-century in the first innings, helped the tourists reach 202 for seven -- after they slumped at one stage to 131 for five -- to leave them with a 185-run lead over the hosts with three wickets in hand.
Earlier, India took their overnight score of 435 for five to 495, giving them a slender first-innings advantage of 17 runs.
Sachin Tendulkar, who was on 191 overnight, recorded his sixth career double-century -- and his second in four Tests -- eventually being bowled by Peter George for 214 to give the Australian paceman his first-ever Test wicket.
However, Tendulkar's dismissal on 486 for five resulted in a lower-order collapse as the last five Indian wickets fell for only nine runs.
A victory in Bangalore will see Australia tie the two-Test series after India claimed a dramatic one wicket win in the first Test in Mohali.
