KKR captain Gautam Gambhir's decision to induct Shakib Al Hasan at the expense of seasoned Brett Lee backfired badly as the reigning IPL champions missed out a genuine paceman on a pitch that was assisting the faster bowlers.
Apart from Mahmood, Lou Vincent (30), Martin Guptill (25) and Anaru Kitchen (24) also came up with useful contributions.
Brendon McCullum top-scored for the Knight Riders with a 35-ball 40, which was laced with two sixes and three fours. But the Knight Riders could not build partnerships and lost wickets in regular intervals.
