Colombo, Sri Lanka: Skipper Rohit Sharma and off-spinner Washington Sundar helped India enter the T20 tri-series final with a 17-run win over Bangladesh in Colombo on Wednesday.
Sharma's dominant 89 guided India to 176-3 and then Sundar claimed three wickets to restrict Bangladesh to 159-6.
Mushfiqur Rahim's unbeaten 55-ball 72, his second successive half-century, went in vain as India secured their third win in four matches.
They now await the winner of the last league contest, which is a virtual semi-final between Bangladesh and hosts Sri Lanka on Friday.
Sundar got three top Bangladesh batsmen including dangerous left-handed opener Tamim Iqbal for 27 to derail the opposition chase at 40-3.
Mushfiqur then put on 65 runs for the fifth wicket with Sabbir Rahman, who made 27, to give India a scare but the increasing run-rate finally got to the Bangladesh chase.
Sundar returned impressive figures of 3-22 while leg-spinner Yuzvendra Chahal and pacemen Mohammed Siraj and Shardul Thakur claimed a wicket each.
Earlier Sharma, who hit form after scores of 0, 17 and 11, smashed five fours and as many sixes in his 61-ball knock after India were put into bat first.
