It was in the second half that Rashid led SRH's counter-attack after Delhi were comfortably placed on 95 for 1 at the halfway stage.
DD had got an excellent start when they were 95/1 after 10 overs but could manage only 68 runs in the next 10 overs to finish at 163/5.
SRH were provided the flawless platform for their chase with Alex Hales and Shikhar Dhawan adding 76 runs - the team's best opening partnership this season. The Delhi Daredevils missed opportunities as they failed to make the most of their promising opening in batting and then released the pressure against their opponent SRH.
Maxwell's dismissal saw Iyer joining in-form opener Shaw in the middle and the duo helped their side recover from the early jolt taking Delhi past the 50-run mark in 5.4 overs. Right at the end, Yusuf Pathan struck two fours and two sixes in his 27 not out - made from 12 balls, to complete the job.
While Shaw has 140 runs from four games, Iyer and Pant have amassed 307 and 375 runs respectively from nine games each. Both of them have looked off colour and the team would want their big guns to fire.
With two new batsmen at the crease, the Sunrisers rebuilt as Williamson and Manish Pandey shared a 46-run third-wicket partnership but Liam removed the latter and conceded just four runs off the 18th over to give the Daredevils hope. Under Kane Williamson they've become a formidable side and are six from eight and looking likely to secure one of the top two spots that gives them two bites of the cherry in terms of making the final.More news: MEA in touch with Afghan authorities after seven Indians abducted
Iyer got out for 44 runs off 36 deliveries while Rishabh Pant played an inning of 18 (19). It was unplayable delivery as Hales looked in utter disbelief.
DROPPED! Yusuf the new man in tries to pull the 4 delivery, he doesn't get much on it as the ball sails towards Vijay Shankar at deep backward square leg, but Shankar can not hold on it.
In the spin department Iyer can turn to veteran Amit Mishra, and Shabaz Nadeem.
The skilful Rashid Khan cut short Shaw's innings with a fastish leg break.
The absence of their most experienced seamer Bhuvneshwar Kumar has barely been felt even as skipper Kane Williamson is bullish about Bhuvi's return. He has leg-spinner Yuzvendra Chahal (7 wickets, nine games) for company but Mohammed Siraj, Murugan Ashwin, Washington Sundar and Tim Southee have been rotated as RCB are yet to find a set bowling line-up. Pacer Siddarth Kaul, who has been quite frugal so far, was hit for 20 runs in his first over. Bhuvneshwar finished with figures of 4-0-33-0.
He lauded SRH players Shikhar Dhawan, Rashid Khan, Siddharth Kaul and Wriddhiman Saha for their performances in the tournament.
