Devon Conway smashed a third consecutive half-century to set up a crushing 91-run Indian Premier League win for Chennai Super Kings over Delhi Capitals.

Fifth-placed Delhi missed a chance to move two points behind Royal Challengers Bangalore and Rajasthan Royals at DY Patil Stadium, where CSK registered only a fourth win of the tournament.

Conway blasted 87 off 49 balls with support from Ruturaj Gaikwad (41) and Shivam Dube (32) as the Super Kings racked up 208-6 after Rishabh Pant won the toss and put them in.

The Capitals were all out for 117 in reply, Moeen Ali claiming brilliant figures of 3-13 from four overs in a one-sided contest on Sunday.

New Zealand opener Conway and Gaikwad got CSK off to an excellent start, taking them to 57 without loss at the end of the powerplay.

Anrich Nortje (3-42) ended an opening stand of 110 when he dismissed Gaikwad with the last ball of the 11th over, but Dube was dropped by Axar Patel on 14 during a partnership of 59 with the prolific Conway.

Khaleel Ahmed, the pick of the bowlers with 2-28, denied Conway a century when he had the left-hander caught behind by Pant before MS Dhoni added a quickfire unbeaten 21.

Delhi – without Prithvi Shaw after he was hospitalised with a virus – lost openers Srikar Bharat and David Warner early in their reply before Mitchell Marsh, who top scored with 25, and Pant (21) got starts but failed to push on.

Moeen saw the back of that dangerous duo in quick succession and the wickets continued to tumble, with Delhi all out in the 18th over.

Conway making hay at the top of the order

Conway only needed 27 balls to reach his latest half-century, hitting five sixes and seven fours in a scintillating knock.

He has scored 231 runs from four innings, averaging a mammoth 77.

Masterful Moeen puts Delhi in a spin

England all-rounder Moeen not only took three wickets, but also bowled 16 dot balls in a fine display of spin bowling.

Moeen conceded just one boundary (a six) as CSK dominated with bat and ball.
