Pathan, who opened bowling, rocked the KKR innings with his inswinging deliveries as he took two wickets in the first over itself.
KKR captain Gautam Gambhir continued his poor form as he was the first one to go for a golden duck in the third ball of the innings. He holed out to Pietersen at mid-on failing to negotiate an inswinging delivery.
Three balls later, Pathan had Bisla (1) for his second wicket. Bisla missed another inswinging delivery and was plumbed in front of wicket.
