Sachin Tendulkar stroked a magnificent 117 to guide India to a six-wicket victory over hosts Australia in the first CB Series final.
Tendulkar's unbeaten innings came off just 120 balls and allowed his side to chase down a target of 240 with 4.1 overs to spare at the Sydney Cricket Ground.
Matthew Hayden contributed 82 to help Australia recover from the loss of three early wickets and post a total of 239-8 after they had opted to bat first.
But that proved inadequate as Tendulkar dominated all the Australian bowlers while compiling the 42nd one-day international century of his decorated career.
Thrill of the chase
The tone of the run chase was set during an opening stand of 50 in 11 overs between Tendulkar and Robin Uthappa (17).
But Uthappa's dismissal, brilliantly caught by Michael Hussey at deep square-leg from the bowling of medium pacer James Hopes, was the first of three quick wickets as India were reduced from 50-0 to 87-3.
Gautam Gambhir (3) was run out by Mitchell Johnson's throw from the point boundary after attempting to come back for a second, and Yuvraj Singh (10) was bowled between bat and pad by Brad Hogg's quicker delivery.
But Tendulkar continued to make serene progress and found a willing ally in Rohit Sharma to add 123 for the fourth wicket.
And shortly after shrugging off a Brett Lee (0-33) beamer, he reached three figures for the first time in a one-dayer in Australia from 106 balls.
With 30 still required Sharma was bowled for 66 playing back to Hopes (2-42). That brought skipper Mahendra Singh Dhoni (15no) to the crease to assist Tendulkar in taking India across the winning line with 25 balls remaining.
Earlier, Hayden's 82 allowed Australia to recover from 24-3 to reach a respectable total.
Adam Gilchrist, Ricky Ponting and Michael Clarke were all back in the pavilion within the first six overs.
Praveen Kumar (2-49) accounted for Gilchrist (7) and Ponting (1) in successive overs, while Ishant Sharma (1-32) - who was later taken to hospital for an x-ray after hurting the middle finger of his right hand while bowling - had Clarke (4) caught behind.
Hayden and Andrew Symonds got the innings back-on-track by adding exactly 100 in 17.2 overs.
Both then fell to catches on the leg-side from the bowling of Australia's nemisis Harbhajan Singh (2-38), who Hayden had been reprimanded for calling an 'obnoxious weed' during the pre-match build-up.
The lower middle order at least ensured Australia had something to defend - Hussey led the way with 45 and was supported by solid contributions from Hopes (15), Hogg (23no) and Lee (17).
The result puts India 1-0 up in the best-of-three final and gives them the opportunity to clinch the trophy in Brisbane on Tuesday.
