| ball |
In baseball, the strike zone is a conceptual rectangular area over home plate which defines the boundaries through which a pitch must pass in order to count as a strike when the batter does not swing. The top of the strike zone is the mid-level between the top of the batter's shoulders and his belt, and the bottom is at the level just beneath the knee cap. The right and left boundaries of the strike zone correspond to the edges of home plate. ...
