ProNine PTB-9 Plastic Training Baseballs – 9 Inch – Set of 6

ProNine PTB-9 plastic training balls are perforated, lightweight practice balls in white, built with a tough plastic construction that prevents cracking and swelling. In this family the PTB-9 is the baseball-size ball in the family. Great for training exercises and batting practice, anywhere space is tight. Sold as a set of 6.

Plastic Balls That Outlive the Cheap Ones
Everyone has a bag of split, egg-shaped plastic balls in the dugout. ProNine’s tough plastic construction prevents the cracking and swelling that kills them, and the uniform holes provide maximum accuracy in flight, so drills stay honest. The perforated, lightweight design keeps flight short and safe for backyards, garages, and gym corners.

High Volume, Low Consequence
Perforated plastic is the highest-rep, lowest-risk ball in training: soft toss, front toss, tee work, and close-range batting practice, with no dents in the bat, no marks on the wall, and no fear in the hitter. The 9 inch size keeps the visual matched to the baseball your players hit on game day.

Where It Fits
The family covers three sizes: the ProNine PTB-5 and ProNine PTB-12 are the other two. For a foam ball that flies truer off the bat, step up to the Lite Flight foam baseballs. The rest of the wall is in the training balls collection.

What are perforated plastic balls best for?
Batting practice and training exercises at close range: soft toss, tee work, and hand-eye drills where a hard ball is unsafe or impractical. The light weight keeps flight distances short.
Which size do I need?
Match the sport: 9 inch for baseball, 12 inch for softball. The 5 inch ball is a deliberate challenge; hitting a smaller ball sharpens tracking before you return to game size.
