US-born Aman Rao hammered a scintillating double century as out-of-reckoning Hyderabad thrashed Bengal by 107 runs in a Group B match to dent the latter’s quarter-final hopes here on Tuesday.

Rao, 21, who was signed by Rajasthan Royals at the IPL auction, smashed 12 fours and 13 sixes en route to his 200 not out from 109 balls to take Hyderabad to a commanding 352-5. Sent in to bat, Rao tore apart a Bengal bowling attack featuring Mohammed Shami (3-70), Akash Deep (0-78) and Mukesh Kumar (0-55).
