Kolkata, May 21 -- The fight for the final IPL playoffs place intensified as Kolkata Knight Riders rode forties from Manish Pandey and Rovman Powell to beat Mumbai Indians by four wickets here on Wednesday. Opting to field on a two-paced Eden Gardens pitch, KKR restricted Mumbai Indians to 147/8 in a rain-extended innings riding on two-wicket hauls from pacers Saurabh Dubey, Cameron Green and Kartik Tyagi while spinners Varun Chakravarthy, Anukul Roy and Sunil Narine combined to concede just 47 runs in nine overs. Having performed that chokehold on Mumbai's innings, KKR came out facing a required run rate of less than 7.5. Deepak Chahar straightaway put pressure on KKR by inducing an inside edge off Finn Allen's bat back on to his stumps. Ajinkya Rahane showed some good form before being dismissed on 21, Green following soon after. Pandey (45 off 33 balls) and Powell (40 off 30 balls) then added 64 runs for the fourth wicket before both departed in the space of three balls. Rinku Singh however stayed put to ensure KKR's tally went up to 13 points with one match still remaining. It was a closer affair than anticipated, and could have gone either way had Mumbai got some more runs. But they started on a shaky note, Ryan Rickelton scratching around for a while before swinging across the line and top-edging Green to Pandey at point. Brief scores: MI 147/8 (C Bosch 32*, S Dubey 2/34, C Green 2/23, K Tyagi 2/37). KKR 148/6 in 18.5 overs (M Pandey 45, R Powell 40, C Bosch 3/30). KKR won by 4 wickets....
