An opening blitz from Brendon McCullum (62) and Dwayne Smith (46) made light work of the Mumbai Indians’ total of 183, dealing out a fourth consecutive defeat for the hosts, as the Chennai Super Kings kept up their 100% record in this year’s Indian Premier League with a six-wicket win.

McCullum and Smith scored 90 in the power play – the second highest opening six overs in IPL history – with Mumbai’s left-arm spinner Jagadeesha Suchitch’s two overs in that period going for 33. When both openers eventually departed, to Harbhajan Singh, only 69 more runs were needed, with eight wickets and 72 balls remaining. In the end Raina’s unbeaten 43, from 29 balls with four fours and two sixes, saw Chennai home with 20 balls to spare.

In fact, had it not been for half-centuries from the Mumbai captain, Rohit Sharma, and the West Indian Kieron Pollard, the game might have been over sooner after they lost Parthiv Patel, Corey Anderson and Lendl Simmons for 12. Much of that destruction was down to Ashish Nehra (three for 23), whose left-arm swing removed Patel first ball and had Anderson trying to force the ball down the ground and being caught superbly by a back-tracking Faf du Plessis.

When Sharma fell, he had played a part in a fifth-wicket partnership of 75 with Pollard. The pair were then backed by Ambati Rayudu, who hit 29 from 16 to take Mumbai to what looked a respectable score until McCullum and Smith set about their bowlers.
