Fifties from captain Nitish Rana and Rinku Singh led the Kolkata Knight Riders to a six-wicket win over the Chennai Super Kings on Sunday.

Kolkata kept Chennai down to 144-6, a total they overhauled riding on a key stand of 99 between Rinku (54) and Rana (57*) in Chennai.

Spinners Varun Chakravarthy and Sunil Narine took two wickets each to set up victory as Kolkata jumped a spot to seventh in their attempt to finish the league stage in the top four for a playoff berth.

Four-time winners Chennai remain second in the 10-team table led by holders the Gujarat Titans and on course for the playoffs.

Kolkata looked in trouble at 33-3 after Chennai pace bowler Deepak Chahar’s third strike to send back Jason Roy, before the left-handed pair of Rinku and Rana guided the team home with nine balls to spare.

Rinku, who became an IPL sensation with his five sixes off the last five balls to conjure up a miracle win for Kolkata last month, struck his second fifty of the season before being run out.

Rana made most of a dropped catch on 18 to reach his fifty and stood firm to hit the winning runs.

Four-time winners Chennai started strongly but slipped from 61-1 to 72-5 in the space of 19 balls before Shivam Dube revived the innings with his unbeaten 48.

Dube kept up the fight in his 34-ball knock laced with three sixes but it was superstar and captain MS Dhoni who brought the house down in his team’s last league game at MA Chidambaram Stadium.

Dhoni, who many suspect is playing his final IPL, walked in to a deafening roar as he faced four balls including a wide and no-ball on which he was bowled but ended on 2*.
