RCB were 23 for 2 in the fourth over when Faf du Plessis and Rajat Patidar joined forces.
Prior to that, Bumrah dismissed Virat Kohli, who swiped and edged behind for three off nine balls in his first over, the third of the innings. In the following over, Akash Madhwal produced his signature skid to dismiss Will Jacks, who made his IPL debut in place of Cameron Green, caught at mid-on for eight.
Du Plessis attempted to salvage the powerplay by positioning himself on the leg side of the ball and using his hands to hit the ball over the top. Patidar also started quickly and eventually surpassed du Plessis to become the first of many half-centurions in the game.
Patidar achieved this milestone by hitting back-to-back sixes off Gerald Coetzee, but the South African quick responded by bouncing Patidar out for 50 off 26 balls.
