Ever wonder what a batter sees when a 90 mph four-seam fastball is barreling to the plate?
Check out this helpful infographic of how different pitches appear to hitters. From the slider to the curveball, you can see what the baseball looks like as it approaches the plate. As a side note, the red dot that shows up on the slider is pretty interesting.
Not too sure how much this will help your game, but it's very cool nonetheless.
