Skipper Kumar Sangakkara lashed 78 off just 37 balls to inspire the Sri Lankan cricketers to a 29-run win over India in the first Twenty20 international in Nagpur.
Sangakkara hit 11 fours and two sixes, his fourth Twenty20 fifty off 21 balls equalling the fastest by a Sri Lankan, until he was run out off the final delivery of the innings.
Sri Lanka made 215 for five after being put in on a good pitch and then restricted the hosts to 186 for nine.
The second and final game will be played in Mohali on Saturday.
