No result - rain
India 9-1 (2.4 overs v Australia 307-7 (50 overs)
Michael Clarke's third century in one-day internationals helped Australia post 307-7 against India in Bangalodre. 
But rain began in the third over of India's reply, preventing the tourists from making a winning start to the seven-match series.
Sachin Tendulkar had already fallen lbw to Mitchell Johnson to leave India 9-1.
Australia were 90-4 after Sree Santh (3-55) ripped through their top order and Clarke was lucky to survive an lbw shout on 31 on his way to 130.
He hit three sixes in his 132-ball knock, putting on 144 with Brad Haddin, who made 69 in 83 balls.
Clarke was run out in the last over but Australia were well in charge.
The advantage grew as Tendulkar was pinned by an inswinging yorker from left-armer Johnson.
The weather worsened almost immediately though and, despite hopes of a resumption later, drizzle returned to finally finish the matter.
"The entire playing area is quite wet. We don't think it would dry before the cut-off time. So we have decided to call it off," said umpire Suresh Shastri.
"We had a discussion with the two captains. The Australians were obviously keen to play but the decision is not either captain's."
Australia were led by Adam Gilchrist, with Ricky Ponting ruled out by a hamstring injury, while Sourav Ganguly, Rahul Dravid and Tendulkar returned for India after sitting out the World Twenty20.
And it was the home side who were rampant early on as Gilchrist slashed Zaheer Khan to backward point and Yuvraj Singh hurled himself to his right to pull off a stunning catch.
Santh swung one in to trap Hodge in front, while Matthew Hayden pulled RP Singh for a six before Santh bowled him as he attempted a big heave.
When Andrew Symonds was plumb lbw to a slower Santh delivery the Aussies were in trouble and it could have got worse if Clarke had been dispatched in similar circumstances by the umpire when Irfan Pathan rapped his back pad.
But the right-hander survived and began to unfurl the kind of strokes which helped him make a Test century on debut at the same venue.
He punished a regular diet of poorly directed balls to reach his century in 108 balls, with two maximums coming in one over from spinner Ramesh Powar.
After Haddin was stumped off Yuvraj, Clarke and James Hopes - who escaped when Powar dropped a return catch early on - scored at nine an over to take the total past 300.
In the final over, Hopes was snapped up at long-on and Clarke was run out by Zaheer right at the end.
