While Khalid Ahmed justified captain Nazmul Hussain Shanto's decision to bowl first on a green surface, opener Nishan Madushka (2) was forced to be caught by Mehdi Hasan at third slip at the end of the second over.
Dimuth Karunaratne and Kusal Mendis put on 37 runs for the second wicket, before Khalid struck again when Mendis was caught by Zakir Hasan at gully off the fast bowler.
Mendis was out for 16 and Khalid bowled Karunaratne with an in-swinger for 17 in the same over.
