Hyderabad scored 59 runs in the last four overs and that propelled them to a fighting total. Ashish Reddy played a very useful unbeaten cameo of 36 and his 43-run partnership with Dhawan was crucial in their revival.
Dhawan's unbeaten knock came off 45 balls with 10 shots to the fence while Reddy's 36 came off 16 balls with two fours and three sixes.
At one time, it looked that there would be no end to Hyderabad's batting woes but inclusion of Dhawan, who missed first seven games due to a hand fracture, lifted the side.
More than the bowling it was exceptional fielding that gave Chennai two early wickets. Murali Vijay took a firmly-hit but uppish shot by Quinton de Kock (4) at mid-on off Mohit Sharma while Suresh Raina's direct hit from covers area sent back Hanuma Vihari (2).
