The loss to Mumbai Indians would have hurt the Kolkata Knight Riders but what was even more heartbreaking were figures of the most expensive buy of the last IPL auction, Pat Cummins. The Australian disappointed in his very first match of the season as he gave away 49 runs in his 3 overs without taking a wicket. But KKR skipper Dinesh Karthik has defended the fast bowler who was bought by the Knight Riders for Rs.15.5 crore.Karthik said that it's very unfair to judge him right now as he just came out of quarantine. He added that Cummins is one of the best going around in the world and he trusts him completely. Karthik is sure that the Aussie will come good.
