Nagpur:Australia stretched their lead to 415 runs at the end of third day of the third Test against India at the VCA stadium today. The Aussies took little more than an hour to dismantle the lower order of the Indian innings in the morning. But the visitors once again chose not to enforce the follow-on after skittling out the Indians for a paltry 185 in the first innings. It was the second time in the series when the visitors had opted to bat on despite a lead of over 200. Early blow Australia's opening stand was worth just 19 runs as Matthew Hayden was out to Zaheer Khan whose first innings five-wicket haul was one of the bright spots for India in this game. The Australians were getting frustrated with a tight spell of bowling and so was the Indian stand in captain. With Langer out to Kartik for 30, it was left to the number three batsman Simon Katich to steady the ship. However, he was lucky to get a few close lbw shouts going in his favour. But Katich held firm and seemed quite comfortable to take his runs off Kumble who wasn't at his usual miserly best. Katich, however, missed out on his century and was trapped leg before wicket by Kartik for 99. His dismissal left the Aussies at 171/3 Michael Clarke, promoted up the order in place of injured Lehmann, then finished the day on 10 not out along with Martyn on 41. Australia extended their lead to 415 and barring the weather, looked set to win their first series in India in 35 years.
