While opener Anamul Haque build the foundation with a patient 100 off 132 balls with six fours and four sixes, it was their senior-most stars Mushfiqur Rahim (51 no, 33 balls) and Shakib al Hasan (44 no, 16 balls), who finished the innings with a smashing 77-run partnership in only 5.3 overs.
Opener Imrul Kayes (59 from 75 balls; 5x4, 2x6) who added 150 runs for the opening stand with Anamul and Mominul Haque (51 off 47 balls) also made useful contributions to prop up Bangladesh total.
Skipper Rahim also struck eight fours while Mominul with six boundaries also made their presence felt with eye-catching knocks.
A win for Bangladesh would also boost India's hopes as they would have to win by a bonus point against Afghanistan tomorrow. Should there be a tie in the points tally net run rate would come into play.
Nothing went Pakistan's way in the match. From spilling a catch at slip when Kayes was on zero in the first over to a some woeful misfieldings that had Misbah-ul-Haq dumbfounded, Pakistan looked disjointed and disoriented right from the start.
