Kolkata Knight Riders (KKR) all-rounder Andre Russell described his unbeaten knock of 70 runs, which included eight sixes, as a big achievement after KKR chased down a 138-run target in 14.3 overs against Punjab Kings (PBKS) to register their second consecutive win of the season at Wankhede Stadium in Mumbai on Friday. However, Kolkata Knight Riders got off to a decent start with openers hitting consecutive boundaries, but Punjab's Kagiso Rabada dismissed Ajinkya Rahane while Odeon Smith got the wicket of Shreyas Iyer and Rahul Chahar struck twice dismissing Shreyas for 26 and Nitish Rana for a duck to leave KKR tottering at 51 for 4.
