India paceman Umesh Yadav says an assured place in the Indian Test team has helped him explore his weaknesses and strengths as a bowler which has boosted his confidence. Yadav, who has improved on hitting right line and length consistently, said he has worked hard to cut down his errors after criticism from media. "I'm doing the same thing but the confidence level is high, having played more matches. And the hard work is paying off. When I was in and out of the team, I was not sure what to do. With more matches, I began realising what to do and what not. I slowly realised my strength and weaknesses. Now I have a better idea," Yadav said. "A lot was written in the media earlier that I bowl a leg-stump line and concede boundaries on the leg side. I have cut that off in a big way and slowly I got back to my rhythm. Trying to bowl in a best way."
