Pat Cummins blasted an astonishing record-equalling half-century to secure a five-wicket Indian Premier League win for Kolkata Knight Riders over Mumbai Indians.

The Indians posted 161-4 at Maharashtra Cricket Association Stadium in Pune, Suryakumar Yadav top scoring with 52 off 36 balls with support from Tilak Varma (38 not out) and Kieron Pollard (22no).

Mumbai looked to be on course for their first win of the tournament when KKR were 101-5 in the 14th over, but Australia Test captain Cummins had other ideas.

The paceman matched KL Rahul's record for the fastest IPL half-century from 14 balls and put the Knight Riders top by hitting Daniel Sams for six to seal victory with four overs to spare, Venkatesh Iyer also playing a big hand with an unbeaten 50.
