Lasith Malinga held his nerve with the final ball as Mumbai Indians beat Chennai Super Kings by one run to clinch their fourth Indian Premier League title on Sunday.
After Shane Watson’s belligerent 80 off 59 balls, Chennai needed two runs off the last ball to overcome Mumbai's 149 but the Sri Lankan veteran trapped Shardul Thakur leg-before to claim the win.
Malinga gave away 49 runs in his four overs but the last two overs by the Sri Lankan and Jasprit Bumrah who took 2-14, were crucial for both sides.
Kieron Pollard smashed an unbeaten 41 off 25 balls to set up Mumbai’s 149 after they elected to bat first.
Watson batted through the Chennai innings until he fell short of his ground in the final over, going for a reckless second run. He smashed four sixes and eight fours in his 59-ball knock.
Ishan Kishan’s direct hit at the bowler’s end sent M.S. Dhoni to the dugout as the defending champions were found wanting in trouble at 82-4.
Earlier, Chennai leg-spinner Imran Tahir took 2-23 to surpass fellow South African Kagiso Rabada to top the bowlers list with 26 wickets.
Deepak Chahar took three wickets while fellow quick Shardul Thakur took two.
Faf du Plessis then came all guns blazing to give Chennai a flying start with his 26 off 13 balls.
Indian batting legend Sachin Tendulkar, now working as a mentor for Mumbai Indians, nervously watched the finale, frequently burying his head in his hands.
"The key moment was Dhoni's run-out," he said.
"But also in patches when Bumrah bowled those critical balls to even out Malinga's one poor over was also crucial.
"And the last over, I thought Malinga finished the game out beautifully."
Mumbai won the IPL in 2013 and 2015 – both against Chennai – and again in 2017 when they beat Rising Pune Supergiant by one run.
