We have a 70’ outdoor cage here in the San Diego area… my two son’s (9U & 11U players) hit this past weekend and these balls performed great! In fact, they were actually more accurate into our pitcher’s pocket target than our ‘‘machine only’ baseballs. Using a HA Jr from roughly 50’ with a 55 MPH setting, these balls flew true and were fun to hit. They were actually about 2-3 MPH faster (avg’d 57 MPH) at this same distance when compared to our traditional pitching machine-only baseballs. Thank you!
Awesome feel and response off the bat. Fly straight and true at high speed. Top of its class!!!
Live using the seam balls for off speed pitches. Sit back and hammer away with no concern of having the ball come back on you.
I’ve used all the other balls and they don’t come close to PL balls. BUY THEM!
Great ball for consistency. Paint to corners with a fast fall with no worry on the ball taking a different flight or changing direction. Best ball on the market !
