The hosts started off horrendously as RCB pacer Umesh Yadav removed opener Suryakumar Yadav and Ishan Kishan in successive balls with MI struggling at 0/2. The home team had put a mammoth score of 214/6 on the board with Rohit Sharma being the top scorer.
Here's a look at how the all the 22 players fared in Tuesday's match.
When he is batting well, he is a hard man to stop and his experience at the global level has also allowed him to understand just how to pace his innings.
Lewis (65) along with Rohit took the score to 60 in the first six overs. The IPL's all-time run scoring leader looks set for another stellar IPL campaign, already with two fifties from four attempts. With what Mandeep Singh and Washington did in the last game.
The Kohli comeback: Staring down the barrel of a chase that required 214 and after omitting big-hitting Kiwi Brendon McCullum at the top of the order, Virat Kohli had a mountainous task ahead of him. Mitch bowled a great spell upfront to get the experienced batsmen out, and then Krunal came in and used his variation to his advantage.
Bumrah kept it neat and tidy during his first spell. They won seven of their remaining eight, and also went on to win the title.
The team India skipper and AB de Villiers are known to share a close bond with each other and everyone knows about Kohli's admiration for the South African star.
MI's batting, on the other hand, failed to rocket off in the first two games and when it clicked the bowlers lost the plot. Mumbai Indians collected 10-plus runs in each over since the end of the 13th and finished off with another massive last over worth 21 runs.
The junior Pandya once again did what he is known for. Total: (for 6 wkts, in 20 overs) 213.More news: CBS To Air Academy Of Country Music Awards This Sunday

Vettori also admitted that RCB spinners could not bowl with freedom. The duo put on a stunning 40-run partnership for the opening wicket to give the away side an ideal start.
Umesh began in a terrific way with back-to-back wickets off consecutive deliveries in the first over.
Is batting first the new bowling first?
Bangalore, who conceded over 200 runs for the second successive game, was restricted to 8-167. Later, Samson came up and scored unbeaten 92 runs.
RCB is led by Indian skipper Virat Kohli, who seriously contributed in the last game.
Excellent enough for Kohli to take quick notes.
Krunal said: "We've played well in all four games, but now we want to continue this winning run". Rohit was on 32 off 24 then. He managed only five runs off six deliveries before falling prey to Markande's bowling. In each match only one of the "big four" has fired at once.
