Chennai Super Kings equalled Mumbai Indians' record of five Indian Premier League (IPL) titles after M S Dhoni and his men trumped defending champions Gujarat Titans by five wickets in Monday's rain-marred final in Ahmedabad.

Put into bat, Gujarat racked up 214-4 after their number three batter Sai Sudharsan capitalised on a strong start and smashed an incendiary 96 off 47 balls that included six sixes.

Chasing a revised target of 171 from 15 overs after a lengthy rain interruption, Chennai survived intense drama before Ravindra Jadeja sealed victory under the Duckworth-Lewis method hitting the last ball for a four.

The final was originally scheduled on Sunday but incessant rain forced the organisers to move the game to its reserve day. (Reuters)
