Defending champions Kolkata Riders scored a convincing 46-run win over an ever-struggling Pune Warriors here today, to keep alive their outside hopes of qualifying for the play-off stage of the ongoing Pepsi Indian Premier League.

Opting to bat, KKR first rode on skipper Gautam Gambhir's 50 and a late surge by Ryan ten Doeschate (31 off 21) to post a challenging 152 for six, and then dished out a clinical bowling performance to bowl out Pune for 106 in 19.3 overs.
