With Samson and Nair on crease, the chase looked to be in good stead, they didn't let the required rate get too high, attacked the weaker links in the sharp Sunrisers attack and kept the momentum going. Zaheer Khan missed out on his 100th IPL wicket and Yuvraj Singh, who is playing his 200th T20 match, made only 3. David Warner assessed the conditions early, put his head down and conjured up an innings that was very different to his natural game.
Williamson scored 89 runs off 51 balls with six boundaries and five sixes while Dhawan posted 70 runs, studding his 50-ball stint with seven boundaries and a six.
The Daredevils struggled at 110-4 in 15 overs until teen Rishabh Pant, 38 off 16 balls, hammered three sixes and two fours in medium-pacer Umesh Yadav's 16th over that lifted the total to 168-7.
With both sides desperate to avoid three straight losses, Warner stood tall with the bat notching up 70 from 54 balls even as his teammates floundered, with fellow Aussie Moises Henriques falling for nine while Yuvraj Singh was out for a golden duck.
Chris Morris took all four of Sunrisers' wickets for just 26 runs, but the rest of the Daredevils'bowling department - including Pat Cummins (0-37 from four overs) - fell flat. He was on a hattrick in the 19th over after taking the wickets of Dhawan and Yuvraj but Hooda denied him the feat.
# 136 run partnership between Shikhar Dhawan and Kane Williamson for the second wicket came off 98 balls. "Once again, just those partnerships throughout were important and I think the icing on the cake was the couple of boundaries that took us past 180", Kane Williamsons said. He hit two consecutive sixes off Angelo Matthews in the seventh over before to take the Hyderabad score to 80 for one at the halfway mark. The ballooning ball gave Amit Mishra enough time to come in from fine leg and accept the catch.
Samson was dismissed in the fourteenth over when he miscued a slower delivery from Mohammed Siraj and was caught just outside the circle.
Australia opener David Warner carried his bat to set up a much-needed win for Sunrisers Hyderabad over Kings XI Punjab in the Indian Premier League.
Fall of wickets: 1-12, 2-148, 3-170, 4-170. Bhuvneshwar Kumar was impressive yet again, returning figures of 4-0-29-0 when the rest of the bowlers went at almost nine runs an over.
Mathews was dismissed for 31 while Iyer remained unbeaten on 50 off 31 deliveries, as Delhi lost the match by 31 runs.
