Our Testimonials

★★★★★

Players get multiple cuts without rattling their hands.  The balls are extremely durable.  We use them for breaking balls, and they are very true.  Curveballs, right-handed sliders, left-handed sliders, you name it.

These balls are the best thing to come around since I have been coaching. ProLine Balls have given our players so much confidence at the plate.

My hitters love The Proline Balls! Velocity and breaking ball training help my guys slow the game down when it counts. If you can beat these balls, you can beat anyone. Huge confidence booster plus, no hand injuries.

The Proline balls are great for all aspects of training. From the bat to the glove, PLB has it covered! They make it easy to manipulate what you need to work on without having to worry about the wear and tear to your glove or bat!

Balls have been awesome. Definitely helping the kids get use to higher velocity and seeing some movement as well without worrying about getting hit.

ProLine Balls aren't just tools. They're a key part of our daily grind. Our hitters and catchers use them every session to push their development further than ever.

We love ProLine Balls! Great for training high velocity! Great for hitting with wood bats or heavy bats. And incredibly durable!
