ProNine CTB Foam Curve Training Baseballs - Set of 3
The ProNine CTB is a multi-use foam curve training baseball with a spiral design, packed in a set of three colors. The spiral does the teaching: it makes spin visible in flight, which is why ProNine builds it for training to hit breaking pitches as well as everyday hitting and fielding practice. Sold as a set of 3.
See the Spin, Hit the Curve
The hardest part of hitting a breaking ball is reading it early. The CTB's spiral design turns spin into something a hitter can actually see, so batters learn to pick up rotation out of the hand instead of guessing. ProNine specifies it as ideal for hitting and fielding practice and for training to hit breaking pitches, and it improves hand-eye coordination along the way.
Soft Foam, Hard Skills
Because it is foam, coaches can throw the CTB at real speeds from short distance without armor or anxiety. The three-color set keeps drills organized: assign a color per station, per pitch type, or per player and run high-repetition rounds.
Where It Fits
For straight batting practice volume, the Lite Flight foam baseballs and PTB-9 plastic training balls carry the load. The CTB is the specialist for spin recognition. The whole drill wall lives in the training balls collection.

How does a spiral ball teach breaking pitches?
The spiral pattern makes the ball's rotation visible in flight. Hitters practice identifying spin direction early, which is the same read they need against live breaking balls.
Is it only for hitting?
No. ProNine calls it multi-use: the spiral design suits fielding practice and general hand-eye work too, and the foam body keeps every drill low-risk.
