ProNine PMZ9 Zero Foam Pitching Machine Baseballs - Dozen
The ProNine PMZ9 Zero is a foam pitching machine baseball that solves the two problems every baseball coach has with machine work: dented bats and stinging hands. It is a full 9 inch machine ball that weighs just over 3 ounces, with a flat seam designed for machine use, a foam cover, and a solid polyurethane foam center. New to ProNine's pitching machine ball line, it is sold by the dozen.
Will Not Dent Bats
Composite and alloy bats are too expensive to sacrifice to machine batting practice. The PMZ9's foam construction lets hitters take full swings with the bats they actually game with, and take them off the tee-room shelf without worry. It is also the right ball for one-handed trainers and other training bats that regular baseballs punish.
Forgiving on Hands, Honest in Flight
At just over 3 ounces, the PMZ9 takes the sting out of mishits, which keeps young baseball players swinging with intent instead of flinching. The solid polyurethane foam center is molded for a consistent flight, so hitters still get an honest read out of the machine rather than the flutter of a hollow plastic ball.
Built for Machine Feeding
The flat seam profile is made for machine use: it feeds smoothly and releases cleanly for repeatable pitches. Enhanced durability means the ball stands up to the daily grind of team practice instead of shredding after a week in the cage.
Training Applications
Run indoor machine batting practice where a regulation baseball is out of the question, feed soft toss and front toss in tight spaces, or set up a backyard machine station without worrying the neighbors. The PMZ9 pairs especially well with one-hand and short-bat drills where bat protection and hand comfort matter most in baseball training.
Who This Foam Baseball Is For
Youth baseball coaches introducing hitters to machine speed, indoor facilities that need a gym-safe ball, and parents who want backyard machine work without dents in a $400 bat. Softball programs doing baseball-size machine drills will find it useful for the same reasons.

Frequently Asked Questions
Will the PMZ9 work in my pitching machine?
It is built with a flat seam specifically for machine use and is sized like a regulation 9 inch baseball, so it feeds through standard baseball pitching machines. Check your machine's ball-type guidance for foam balls before running it at top speeds.
Will it really not dent my bat?
That is the point of the Zero. The foam cover and foam center are softer than any bat surface, so composite, alloy, and wood training bats are safe.
How is it different from a dimpled machine ball?
Dimpled machine balls are solid and heavy like a regulation ball; they last a long time but they are hard on bats and hands. The PMZ9 is a third of the weight with a foam body, trading game-weight impact for bat safety, hand comfort, and indoor-friendly play.
