The First Pitch XL and the First Pitch Original have the same motor and controller and for the most part are the same. There are three basic differences between the two machines.
The Original has two sets of legs - one for baseball and one for softball. The XL has a single set of adjustable legs, so that only one set of legs is required.
While the Original will tip forward for ground balls and back for high arc pitches, the XL will tip further back to throw pop flies.
The XL has a 360-degree swivel feature for more versatile fielding practice.
