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.


Clear and Immediate Feedback 

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. 


Pitchers will:  

  • Develop command by throwing more strikes and getting ahead of the count
  • Gain control of the strike zone by hitting their target especially with the inside corner of the plate
  • Generate more power to throw their fastball past batters
  • Have better production by getting more strike outs, forcing more ground balls and fly balls, and reducing walks and hits


Position Players will:

  • Become more consistent in making routine throws to players and bases for the “sure” outs
  • Make more challenging, “play-making” throws to players and bases for outs (Whether it’s infielders throwing to first base, outfielders throwing to a cutoff or a base, or catchers firing the baseball to a base)
  • Have better defensive production by throwing with more accuracy and power to their target
