The Tigers are now on tour to Sri Lanka, where they have already played two Tests ( series drawn 1-1), three ODIs ( series drawn 1-1) and play the first match of 2 T20Is today.
The third umpire again was called on and eventually ruled Iqbal out, leaving Sri Lanka to go on and win the match by 70 runs and tie the series at 1-all.
With Kusal finally dismissed by Taskin Ahmed (1-33), it was left to Thisara to knock the same bowler for four and earn victory for Sri Lanka. He shared a vital 65-run alliance inside seven overs alongside fellow opener Upul Tharanga - and eventually departed four balls prior to victory. Perera continued to attack and soon got the required run-rate to about a run-a-ball.
Mashrafe has led Bangladesh in the most number of T20Is, winning nine of those 26 matches.
Bangladesh ended their innings at 155 for 6, thanks to contributions from Mosaddek Hossain and Mahmudulah, who added 57 for the sixth wicket. As far as the Sri Lankan bowlers are concerned, Lasith Malinga picked up 2 wickets, while Vikum Sanjaya, Gunaratne and Prasanna picked up a wicket apiece.
Sri Lanka finally tasted success in the third and final one-day worldwide against Bangaldesh but it was a series of mishaps which really provided the most entertainment.
The visiting side's total, in fact, would have been substantially less - had the gritty Mosaddek Hossain and all-rounder Mohammad Mahmudullah not weighed in with a determined 34 not out and 31, respectively. He also posted a thank you message to his fans and players.
Earlier, Bangladesh skipper Mashrafe Bin Mortaza won the toss and opted to bat first. The second and final T20I wil get underway at the same venue on Thursday. Subsequently, Bangladesh will head to England to play the Champions Trophy in June.
