Pat Cummins equalled the fastest 50 in Indian Premier League history with a devastating spell of hitting that propelled Kolkata Knight Riders to the top of the table.
Australian Test captain Cummins is best known for devastation with the ball but he blitzed five-time champions Mumbai Indians with a 14-ball half-century that transformed the game.
Kolkata required 61 runs from 6.5 overs after England left-armer Tymal Mills dismissed West Indies all-rounder Andre Russell but some astonishing striking saw KL Rahul's effort for Punjab against Delhi four years ago matched in terms of deliveries faced and a five-wicket victory sealed next ball when Cummins crunched his sixth six.
