Kolkata Knight Riders kept their hopes of qualifying for the IPL play-offs on track with a comfortable seven-wicket victory over out-of-reckoning Pune Warriors in Mumbai last night. The visitors first shackled the home team batsmen with their three-pronged spin attack and restricted the Warriors to a meagre 118 for seven and then reached the target by making 119 for three in 16.4 overs. Yusuf Pathan who made a brisk 29 in 25 balls and also took two wickets, was declared the man of the match. Today Mumbai Indians will meet Rajasthan Royals in Mumbai at 8 PM.
