Australia took control of the first Test on day two in Bangalore, reducing India to 150-6 after making 474.

Debutant Michael Clarke hit 151 and shared a sixth-wicket stand of 167 with Adam Gilchrist, who made 104 himself.

Glenn McGrath then took three wickets and by stumps the hosts were still 125 runs short of avoiding the follow-on.

From 4-2 at one point, Sourav Ganguly (45) and Virender Sehwag (39) added 83 for the third wicket but both fell to Mike Kasprowicz' reverse swing.

After McGrath struck twice in his first two overs, dismissing Aakash Chopra and Rahul Dravid for ducks, India were in dire trouble.

The tourists decided to sit back against a potentially explosive third-wicket pair, and runs flowed for a while.

But when, finally, Kasprowicz was brought into the attack to bowl the 21st over, he found reverse swing immediately, dismissing both Sehwag and Ganguly in his first four overs.

Sehwag miscued a flick on the leg-side and was taken by Justin Langer at short midwicket, while Ganguly nicked a delivery that swerved away from him.

McGrath's third victim was an out-of-sorts Yuvraj Singh, who also edged to Gilchrist.

VVS Laxman was the only other batsman to put up any fight with 31 before Shane Warne produced a delivery that spun sharply from outside leg-stump to hit the top of off.

Australia had set a blazing pace during the morning session, Clarke and Gilchrist adding an extra 107 to an overnight total of 316-5 in the 25 overs they were together.

Gilchrist took the pressure off Clarke by taking to the spinners, with two sixes off Anil Kumble and one off Harbhajan.

Clarke fiddled for 40 minutes in the nervous 90s, feeling the pressure of the occasion as his parents and grandparents watched nervously from the stands.

Finally he flicked Pathan on the leg-side, ran hard for two, raised his arms, kissed the badge on his baggy green and leaped for joy at a 170-ball century.

Gilchrist followed him in typically aggressive style, his 11th Test ton coming from 103 balls.

Unfortunately for Australia's stand-in captain, the umpires decided there was enough time to bowl a 26th over before lunch.

Harbhajan pitched the ball up and took a diving catch on his follow-through to account for the left-hander.

Warne followed straight after the break but Clarke was able to add 44 for the eighth wicket, thanks to the stout defence of Jason Gillespie, before edging Zaheer Khan to slip.

Harbhajan completed his 11th Test five-wicket haul in the very next over with the wickets of Kasprowicz and McGrath, quelling hopes of tail-end resistance.

But once those same two men had done their job with the ball, Australia's total appeared at least enough for a commanding first innings lead.
