Opener Jahurul Islam Omee and Mohammad Mithun put Bangladesh A in comfortable 270-6 on the opening day of the three-day match against Sri Lanka A on Sunday at Hambantota.
The match was a four-day game, which was due to be held on September 23 at Katunayake but relentless rain at the venue forced the match to be called off.
However, host Sri Lanka gave Bangladesh a chance to have a match, making it a three-day game.
Mithun scored 92 off 120 with 10 fours and three sixes as he utilized the platform well set by the openers Jahurul Islam Omee and Shadman Islam.
Jahurul made a patient 90 off 210 balls, sending the ball across the rope eight times. Shadman Islam contributed 53 as the opening pair shared a 90-run partnership.
Bangladesh A then faced a collapse as Nazmul Hossain Shanto and skipper Mominul Haque were removed cheaply.
However, Mithun then steadied the ship before he was run out as the fourth batsman.
Soumya Sarkar and Mehidy Hasan Miraj were batting on 8 and 7 runs respectively before the bails were drawn for day one.
