Holding the ball to tight can make your fastball slower?


Have you ever heard about the radar gun syndrome?
Pitchers who are clocked in some range of speed on game f.ex 83-86, drop their fastball when they’re on tryouts with radar guns because they’re getting nervous and want to throw hard and then hold the ball too tight, making their fastball drop to 77-82.


I’ve also noticed as soon as the radar gun comes into play, guys tend to lose their command and control because they get worried about their speed.
