Chasing 203 at Eden Gardens on Sunday night, Chennai's famed batting line-up failed against some disciplined Mumbai bowling. Mitchell McClenaghan did the early damage with the ball, removing Michael Hussey. Dwayne Smith and Suresh Raina tried to repair the innings, but the pair's exit left Chennai a mountain to climb. Harbhajan removed both Smith and Raina before McClenaghan accounted for Bravo to leave the CSK chase in tatters.
And when MS Dhoni fell to Lasith Malinga in the 16th over, the writing was on the wall for the two-time champions.
Earlier, Mumbai Indians posted a daunting 202/5 after Chennai won the toss and decided to field.
Mumbai Indians built their innings around two partnerships, as they set an asking rate of 10.15 for Chennai on a flat strip.
A rollicking 119-run second-wicket stand between opener Lendl Simmons (68; 45b, 8x4, 3x6) and Rohit (50; 26b, 4x6, 6x2) took the team to a position of solidity after the loss of opener Parthiv Patel in the opening over itself.
Kieron Pollard (36; 18b, 2x4, 3x6) and Ambati Rayudu (36; 24b, 3x6) then forged a 71-run partnership for the fourth wicket off only 40 balls to pile on the Chennai Super Kings bowlers' misery.
