Pronine PMZ9 Pitching Machine Zero Foam Baseball 9"

The ProNine PMZ9 Zero Foam Pitching Machine Baseball is the ultimate bat-saving ball for team practices. This full 9-inch machine ball weighs just over 3 ounces, with a foam cover and solid polyurethane foam core on a flat seam for smooth machine feed. It's highly forgiving on mishits and eliminates sting in the hands while still delivering honest flight — perfect protection for expensive composite and alloy barrels. For programs that don't want to sacrifice a game bat to machine reps, the PMZ9 is the safest option in the lineup.

Key features & specs:
