Chasing Sri Lanka's 261, India slumped to 180-6 before the seventh-wicket pair of Mahendra Dhoni and Suresh Raina steered the hosts home with an unbroken 82-run partnership.

Dhoni, India's new one-day wonder who smashed an unbeaten 183 in the previous match at Jaipur on Monday, sealed the impressive win in the 46th over with two consecutive sixes off Russel Arnold.

Dhoni returned bat in hand with a 43-ball 45 and super-sub Suresh Raina justified his substitution at the expense of seamer Sri Sreesanth with an unbeaten 39 off 34 balls.

It was India's first one-day series win on home soil since beating Zimbabwe 3-2 in March 2002 and came with three games in hand in Ahmedabad on Sunday, Rajkot on November 9 and Baroda on November 12.
