Chennai Super Kings claimed a record-equalling fifth Indian Premier League title with a five-wicket win over Gujarat Titans in a rain-affected but thrilling summit showdown here on Monday.

B Sai Sudharsan slammed 96 in 47 balls as Gujarat Titans posted 214 for four after being asked to bat first.

Set a revised target of 171 in 15 overs after rain interrupted play at the start of the second innings of a final that was pushed to the reserve day owing to heavy downpour, CSK completed the task in the last ball at a packed Narendra Modi Stadium in what could turn out to be the legendary Mahendra Singh Dhoni's final outing in the T20 league.

Ravindra Jadeja struck a six and a four off Mohit Sharma in the final two balls to win it for CSK.

Earlier, GT were off to a flying start with their opening duo of Wriddhiman Saha and Shubman Gill putting on 67 runs in seven overs.

While Gill was sent back by star left-arm spinning all-rounder Jadeja for a 20-ball 39, Saha went on to make 54 off 39 balls to lay a strong foundation for a formidable total.

Saha was dismissed by seamer Deepak Chahar, who had dropped Gill when the batter was on 3.

Sudharsan, who has also been in good form in recent times, hit six sixes and eight fours in his whirlwind knock.

Tushar Deshpande gave away 56 runs in his four overs.

Brief scores: Gujarat Titans: 214/4 in 20 overs (Sai Sudharsan 96, Wriddhiman Saha 54).

Chennai Super Kings: 171/5 in 15 overs (Devon Conway 47, Ajinkya Rahane 27, Shivam Dube 32 not out, Ravindra Jadeja 15 not out; Mohit Sharma 3/36, Noor Ahmad 2/17).
