Leg-spinner Varun Chakravarthy's five-wicket haul and scintillating half-centuries from Nitish Rana and Sunil Narine combined to hand Kolkata Knight Riders (KKR) a valuable 59-run win over Delhi Capitals (DC) in an Indian Premier League (IPL) match and remained in fray to qualify for the playoffs.

The win gives KKR a boost to their net run rate as they look to fend off challenges from SunRisers Hyderabad, Kings XI Punjab and Rajasthan Royals below them in the race for the final playoff spot.
