India have scored 99 runs losing six wickets in their second innings at tea, chasing a daunting target of 441 runs on the third day of the first cricket Test. India need another 341 runs with four wickets in hand to avoid a defeat.Earlier, Australia were all-out for 285 in their second innings at lunch against India, as their overall lead swelled to a gigantic 440 runs. The Australian skipper scored 109 off 202 balls with 11 boundaries, an innings that will certainly be considered as one of the best by an overseas batsman on a devilish Indian track which had sharp turn and bounce. It was his fifth consecutive century against India in as many Tests.If India manage to achieve the uphill target, it will be highest by any team in the history of Test cricket. India's highest ever run-chase was 387 against England in Chennai back in 2008, when Virender Sehwag played a blinder on the fourth evening to set up the victory.Australia today added 142 runs in the extended opening session in 41 overs after. Skipper Steven Smith once again turned out to be a nemesis with a superb century on dodgy track. He curbed his natural attacking instincts to slowly and steadily using his feet to good effect.For the hosts, Ashwin's analysis read 4 for 119, while Jadeja ended up with innings figures of 3 for 65. Umesh Yadav finished with 2 for 39 to add to his 4 for 32 in the first innings.
