There's a long going conversation about the benefits of live arm vs. pitching machine batting practice.
In a nutshell, here's how the debate sounds:
- The problem with pitching machine batting practice: the machine looks different than a pitcher, lacking the rhythm and timing you see with a live arm. The benefits of using a pitching machine are its consistency of pitches and unlimited energy.
- The problem with live arm batting practice: inconsistency of pitches and limited energy of pitcher(s). The benefit of having a live arm batting practice is that the hitter can practice rhythm and timing, unlike a standard pitching machine.
