Watson hammered an unbeaten 89 after having taken 3-19 as Rajasthan scored 134 without loss off only 13.1 overs in reply to Mumbai's mediocre 133-5 at the Wankhede Stadium.

Watson's solid partnership with Rahul Dravid (43) left a Mumbai side led by Sachin Tendulkar frustrated as the ball was punished to all parts of the ground.

Mumbai stays in contention for the playoffs despite a third consecutive defeat, with 16 points from 13 games.

Rajasthan, already out of contention, finished its 14 games with 13 points.

“When someone of the class of Shane Watson plays like that, he shows you how good he is,” Warne said after his last game. “I have had four great years in the IPL and hopefully I have helped Indian cricket and the young players here.” Watson smashed six sixes and nine fours during his 47-ball knock to complete what was only the third 10-wicket victory in four editions of the IPL and the only one this season.

He set the tempo with two sixes in the second over of the innings bowled by off-spinner Harbhajan Singh. He also lofted three sixes off Sri Lankan pace bowler Lasith Malinga, who normally concedes few runs, and one off another seamer, Dhawal Kulkarni.

“It has taken me a little while to do that,” Watson said after recording his first half-century of this IPL. “It's always nice when two parts of your game come together.” Earlier, Mumbai was helped to a fighting total by Rohit Sharma, who produced a brisk knock of 58, his 11th IPL fifty and the third of this edition.

Sharma smashed a six-and-five fours off 47 balls before he fell in the last over of the innings to Warne, who had announced his retirement earlier during the tournament.

Warne bowled well in the middle overs to finish with figures of 1-30, restricting old adversary Sachin Tendulkar, who could not hit a boundary off him during his 35-ball 31.

Warne also used his other bowling resources well. The Rajasthan bowlers managed to even restrict a well-set West Indian all-rounder Kieron Pollard, who made 20 off 18 before becoming Watson's third wicket of the innings.
