Suresh Raina's unbeaten innings of 57 helped Chennai Super Kings beat Mumbai Indians by 22 runs to win the final of the 2010 Indian Premier League.
Raina's 57 came off just 35 balls and included three fours and as many sixes.
Chennai set Mumbai a target of 168 but restricted them to 146-9 to earn the victory with Sachin Tendulkar top scoring for the Indians with 48.
Shadab Jakati took the prized wicket of Tendulkar and was the pick of the Super Kings bowlers with figures of 3-31.
The Super Kings were off to a cautious start with their opening stand of Murali Vijay (26) and Matthew Hayden (17) only worth 44.
However, Raina's half century stand with Mahendra Singh Dhoni (22) helped in part to them setting a target of 168-5 from their 20 overs.
The Super Kings had been struggling at 68-3 at the end of the 12th over but the turnaround came when Raina, who had played himself in nicely was let off twice - first on 13 when a mistimed pull landed safely between Dilhara Fernando and Abhishek Nayar.
He escaped again on 28, when Zaheer Khan grassed another straightforward chance.
The Mumbai Indians were immediately under pressure with off-spinner Ravichandran Ashwin piling pressure on opener Shikhar Dhawan by beginning with a maiden, before Doug Bollinger picked off the batsman by having him edge to Dhoni in the second over.
Tendulkar and Abhishek Nayar (27) got the chase back on track with a 66-run stand, although both presented the Super Kings with several opportunities with shoddy running and calling.
Nayar was eventually run out and Raina, introduced for the first time in the 12th over, also got rid of Harbhajan Singh, who had been promoted up the order, in the same over.
The bigger blow, however, came in the 15th over when left-arm spinner Shadab Jakati removed Tendulkar and Saurabh Tiwary to effectively end Mumbai's hopes of victory.
Two years ago Chennai were beaten by the Rajasthan Royals in the inaugural IPL final, with Deccan Chargers claiming victory over Royal Challengers Bangalore in last year's final.
