Miraj justified his promotion by hitting five fours and a six in the powerplay overs to give Barishal a good start.
After the dismissal of Fletcher (12 off 16 balls) in the sixth over, Barishal sent Mahmudullah one-down and not in-form skipper Shakib Al Hasan, who has been in fine form in the ongoing BPL.
This change in the batting line-up also paid dividends as Miraj and Mahmudullah stitched a second wicket partnership of 69 off 46 balls.
Miraj was the aggressor, bringing up his half-century in 35 balls, while Mahmudullah ably supported him from the other end.
