With Kolkata needing 29 off the final over, Yash Dayal was handed the ball and Rinku was turned loose after Umesh Yadav took a single off the first ball.
The 25-year-old took advantage of three full tosses to clear the ropes and smashed the last two balls outside the off-stump to long-on boundaries as Kolkata sealed a three-wicket win.
Man of the match Rinku said, “I was just trying to hit sixes. I was not thinking much, just reacting to the ball.”
