There is no live pitching in this division but instead, the ball is "pitched" from a machine placed in front of the pitching mound. The rules and format of Machine Pitch are set up to be less intensive play than the upper levels and focus on the teaching and instructional aspects of the game. This is the first level where players begin to learn and play by most of the basic baseball rules.

By having pitches delivered from the machine versus a coach, players are able to more adequately develop hitting skills and positive habits while getting consistent pitches.
