FAST-Balls are strategically designed training aids for Pitchers to develop command and power in pitching 2-Seam and 4-Seam fastballs and for Position Players to throw the baseball more efficiently. 

The word “FAST” in FAST-Balls represents the acronym of Form, Accuracy, & Speed Training Balls.


The 4S/PP FAST-Ball training aid is a patented, ideally-designed half Black and half White baseball where the black/white borderline is exactly across the center of all four baseball seams, so the baseball looks like a Half Moon.  The “4S” stands for 4-Seam.  The “PP” stands for Position Player as they should be throwing the baseball as a 4-Seam fastball. The 4S/PP FAST-Ball training aids are designed to give clear and accurate immediate feedback on the rotation and orientation of a pitcher’s 4-Seam fastball or a position player's thrown baseball.

2S FAST-Ball

The 2S FAST-Ball training aid is a baseball that has Black on each end of the baseball so that a 1-inch White Line remains exactly through the center of the baseball across two seams. The “2S” stands for 2-Seam. These 2S FAST-Ball training aids are designed to give pitchers clear and accurate immediate feedback on the rotation and orientation of their 2-Seam fastballs.

Clear and Immediate Feedback - So what?

The clear and immediate feedback these training aids provide to the pitchers and coaches allows players to make quick minor adjustments to their body position, arm slot, wrist action or finger pressure that are needed to pitch and throw the baseball with better Form, Accuracy and Speed.

Black/White Color Contrast

The Black color and the White baseball cover produces the best contrast of colors to see and receive immediate feedback each of these training aids provide.  Baseball players and coaches will be able to see how these training aids are performing in the air in a variety of lighting and background settings.
