In the next match against Kochi Tuskers Kerala, he scored 37 runs in one over, which included 3 sixes, 3 fours and a no ball that was hit for a six. Although many people cite him as having hit the over for 37, one run was awarded as an extra due to the no ball. He can therefore be said to have hit 36 off an over that went for 37. Gayle won the Orange Cap Award for scoring the most runs in the tournament amassing 608 runs in 12 matches. He was instrumental in many victories for the Royal Challengers Bangalore and received five Man of the Match awards and also the Player of the Tournament award for his performances.

Gayle enjoyed great success in that tournament. He was the leading run-scorer in that series with 293 runs, a top score of 109, and an average over 50, the best of the tournament. The only century Gayle scored in the event ended in defeat as Mid West Rhinos's Brendan Taylor's outstanding 75* outlasted his team.
