WATCH: MS Dhoni asks new skipper Ruturaj Gaikwad to give him a pat on the back

Rohit Sharma hit an unbeaten 105 but his Mumbai Indians fell 20 runs short as they tried to chase down a big target set by holders Chennai Super Kings on Sunday.

Set 207 for victory, five-time winners Mumbai finished on 186/6 even though Rohit raised his ton in 61 balls at his home ground in Wankhede Stadium.

Skipper Ruturaj Gaikwad and the in-form Shivam Dube powered Chennai, who won their fifth title last year, to 206/4.

Gaikwad hit 69 and Dube smashed an unbeaten 66 before warhorse MS Dhoni smashed three successive sixes in the 20th over to take Chennai past 200.

Dhoni came in to bat with four balls left and scored 20 smashing Mumbai skipper Hardik Pandya for three sixes and finished with a two to end a 26-run over.

Sri Lanka quick Matheesha Pathirana then took four wickets to push Mumbai to their fourth loss of the season.

Gaikwad put on 90 runs with Dube before falling to Pandya, but Dube and then Dhoni's cameo ensured Chennai finished strongly.

Mumbai started well with Rohit and Ishan Kishan putting on 70 runs for the first wicket before Pathirana hit back.

Pathirana sent back Kishan and then Suryakumar Yadav, for his second duck this season, in the space of three balls.
