He dropped a crucial catch, but then Quinton de Kock more than made up for it with the bat. The opener stroked a magnificent unbeaten 78 to lead the Mumbai Indians to their fifth win on the trot, as they trounced the Kolkata Knight Riders by eight wickets at the Sheikh Zayed Stadium in Abu Dhabi on Friday night. MI have now beaten KKR 21 times out of 27, and this win, coming with 19 balls to spare, has to be the most comprehensive of those wins. With their sixth win in eight games, the defending champions are again back on the No. 1 spot in the table. Putting in a clinical show, Mumbai showed no mercy as they completely outplayed the Knight Riders, who clearly seemed rattled by its top spinner Sunil Narine being reported for chucking, and then a change of the captaincy baton from Dinesh Karthik to Eoin Morgan just a few hours before a key game. After a superb fightback by Pat Cummins 53 not out and new skipper Eoin Morgan scoring 39, who went through baptism by fire on his IPL captaincy debut, rescued the Knight Riders from 61 for five in the 11th over to a respectable 148 for five, MI came out all guns blazing in the chase.
