Left-arm wrist spinner Kuldeep Yadav believes tweaks in his technique, including a straighter run-up and an aggressive rhythm, has helped him to improve his bowling and achieve success in ODI cricket. The 28-year-old has taken 27 wickets from 14 matches this year, the highest by an Indian bowler in ODIs. "After the (knee) surgery (last year), my run-up has become much straighter, and rhythm has become aggressive. My hand used to fall over but that has been controlled and now it (hand) is facing the batsman,” said Kuldeep in the post-match press conference.
