Kolkata left-arm wrist spinner Kuldeep Yadav thinks his defensive mind set against Mumbai Indians in their previous game in Kolkata may have cost him dear. Kuldeep was having an ordinary IPL till Tuesday night with just nine wickets from 12 outings at an economy rate of around 8.5. But on Tuesday evening, he returned figures of 4/20 against Rajasth Royals as Kolkata defeated the visitors by six wickets to inch closer to a play-off berth .
