"Right now I'm just working on my basics. I'm trying to improve my run-up, make it smoother and get my balance right," said Umesh.
Umesh said that under the guidance of head coach Eric Simons and team mentor TA Sekar he has improved immensely.
"Sekar sir has been telling me that if I remain calm and relax, it will help. So, I am just trying to do that. It helps me bowl better and bowl consistently in my areas," Umesh told Umesh told clt20.Com.
"Before bowling, Eric Simons always gives me target practice. He keeps a patch and I have to bowl on that. It is really helpful for me and sometimes just before the match, while working with Simons, I check my seam position and bowl at him.
"All this has benefited me and I have got my rhythm back. I have also been working on the position of holding my left hand and have improved. Now I don't have too much difficulty in hitting the right areas and I am happy," he added.
The The 24-year-old speedster from Maharashtra said that swing and bounce are his biggest strengths and he is fully exploiting the seamer-friendly conditions in South Africa.

"My strengths are my swing and bounce. I work on both. Bounce in a wicket is important for me, because if there is bounce and I hit the right areas and I can have the batsman in trouble. With a good-length ball, I get the swing and the height the bowler wants, which makes it difficult for the batsman to play shots. So, I like it if there is bounce in the wicket and the ball swings.
"It has been a good experience (bowling in SA). The wickets here are green and have a bit of grass on them as well. It's a fast bowler's dream to be able to play on wickets like these. Since the CLT20 is happening in South Africa, I will definitely benefit from it. As a pacer I have got what I wanted, so I will try and do my best." (MORE)
