Mumbai entered the finals by beating Chennai in Qualifier 1, while Delhi set up a Qualifier 2 battle with them after beating Hyderabad in the Eliminator.
The CSK skipper came into bat with Shane Watson going great guns at the other end but steadily running out of partners. Chennai won the second Qualifier game, thereby lining up to face Mumbai in the all-important final.
In between those two Bumrah overs, Watson kept Chennai in the hunt by lofting left arm spinner Krunal Pandya for three successive sixes in the 18th over before Malinga returned and quashed Chennai's hopes. The result meant Mumbai became the first team to win four IPL trophies.
Chasing 150, CSK fell agonisingly short of clinching their fourth IPL title after they lost by just one run against Mumbai Indians in the finals, here at the Rajiv Gandhi International Stadium on Sunday.
"Can you guys see the blood on his knee", Harbhajan Singh wrote.
Watson nearly proved the saviour in the cliffhanger chase, playing a sensational 59-ball knock in an nearly one-man show as CSK tried to chase down Mumbai's 149 on Sunday at the Rajiv Gandhi International Stadium in Hyderabad.
"That's our @srwatson33, nearly pulled it (off) for us last night", he added.
Shane Wastson batted through the CSK innings until he was run out in the final over, smashing four sixes and eight fours in his 59-ball 80 knock.
Utilising yorkers to good effect, he conceded seven runs off his five balls, which also included the run out of Watson. Though he started the season slowly, he finished the tournament with an impressive 398 runs from 19 matches.
