hello im a 13 yrs old legspinner and when i bowl i usually overpitch the bowl because i often propel the ball too hard or too slow because it seems that to get past the 20 meters i need a lot of energy to propel it so i overpitch it. In training when i overpitch it i dont get hit because our teams batting is sh*t but it can cause me problems in future can you tell me at what distance i should pitch it from the batsman???
