Chennai, May 2 -- Skipper Ruturaj Gaikwad authored a calculated chase in the company of Kartik Sharma, with both scoring unbeaten half centuries, to guide five time winner Chennai Super Kings (CSK) to a commanding eight wicket win over Mumbai Indians in a key IPL contest at the M A Chidambaram Stadium on Saturday tonight, keeping its hopes of a play off spot afloat.

Chasing MI's 159 for 7, the home team lost inform batter Sanju Samson early, despite getting a life, before Urvil Patel (24, 12 balls, 2x4, 2x6) chipped in with a short cameo before Ruturaj and Kartik took over the guantlet on a two-paced wicket and helped CSK cross the finishing line with consummate ease winning by eight wickets with 11 balls to spare.

CSK eventually finished...
