Skipper Barrington Rowland chipped in with 22 and B Akhil contributed 18.
Upul Chandana picked up two wickets for the Bradman XI, while Mohammed Sami, Javagal Srinath and Shoaib Malik secured one each.

CAB Vs NSW:
Cricket Association of Bengal salvaged some pride as they beat New South Wales by 23 runs in their last league fixture.
In the inconsequential match -- as Air India are already through to the final from Group B having defeated these two teams yesterday -- CAB posted 134 for five in 20 overs, on theback of fine batting by Manoj Tiwary who made 55 and Subhomoy Das who hit 45.
Man-of-the-match Tiwary smashed five fours and one six in his 46-ball innings, while Das' breezy knock came in 27 balls with the help of six boundaries and one six. Rohan Gavaskar came up with 21.
NSW faltered in their run-chase and their innings folded up in 19.1 overs for 111.
Sourasish Lahiri was pick of the CAB bowlers taking four wickets for 11 runs while Abhishek Jhunjhunwala accounted for three.
