Krunal Pandya also played a useful cameo, smashing 39 off 26 balls with the help of two fours and as many sixes.
Mumbai openers Rohit Sharma (14) and de Kock put up 49 for the first wicket. The South African fetched his first boundary, a cover drive, and then launched into left-arm pacer Mustafizur Rahman (1/37) for a four and a maximum. While Rohit played his trademark pull-shot to get a six in the fifth over.
De Kock hammered Chris Morris (2/33) for another maximum but Rohit perished in the sixth over, giving a dolly to Chetan Sakariya at mid-on.
