How will batting practice affect a player's batting average?

The more you practice, the better you become, so it will improve a player's batting average.

Batting average is the performance of the batter. This is expressed as the ratio of the batter's safe hits per official times at bats. I would say that battling practice would improve the player's performance because he will be better accustomed to the position he is most comfortable.
