KKR chased down the modest target with two overs to spare with Chris Lynn top-scoring with a 42-ball 45 while skipper Dinesh Karthik remaining not out on 41 off 31 deliveries. Sunil Narine played a typical but brief explosive innings of 21 off just seven balls at the top of the innings to lay the foundation of the successful run chase.Chinaman Kuldeep Yadav scalped four wickets to help Kolkata Knight Riders (KKR) recover from a Powerplay blitz by Rajasthan Royals (RR) openers and skittle them out for 142 in 19 overs.
