India, who lead the two-match series 1-0, elected to field in overcast conditions and fast bowler Akash Deep vindicated captain Rohit Sharma’s decision with two wickets in the first hour of play.
He removed openers Zakir Hasan, caught out for a duck, and Shadman Islam, trapped lbw on 24, with his seaming deliveries to the left-handers.
Captain Najmul Hossain Shanto, who made 31, put on 51 runs with Mominul to play out the remainder of the first session, but first-match hero Ravichandran Ashwin broke the stand after lunch.
Off-spinner Ashwin, who hit a century and took six wickets in India’s opening win, took down Najmul lbw with a turning delivery from around the wicket.
The hosts have come in unchanged with three seamers, who have regularly troubled the opposition batsmen with plenty of deliveries beating the bat.
