Put in to bat, BCB XI piled on 309 for eight in the stipulated 50 overs with the hosts medium pacers coming a cropper on a seaming JU second campus track.
Mohammed Nasir Hossain was BCB XI's top-scorer with 74 off 75 balls but it was their opener Anamul Haque who set the tempo with a 24-ball 44, studded with seven fours and two sixes, even as Bengal strike bowlers Veer Pratap Singh (2/59) and Mohammad Ashrafuddin (1/62) leaked more than seven runs per over.

Bengal and BCB XI with two points each will now have to wait for the result between Mumbai and Karnataka tomorrow for the second finalist's berth.
