Top spin in batting practice

When watching a team take BP, there is nothing more telling of a hitters bat path then how the ball travels off the bat. Does it travel with backspin or does it take off and quickly descend because of topspin?

Those topspin hitters give away the fact that there barrel is below their hands much too early in the swing. To compensate for this collapsed barrel they roll the barrel to the ball and hit the top of the ball causing topspin. This early barrel collapse will eventually catch up to hitters. They might be able to get away with topspin at low levels of amateur baseball but there is a day coming where the fastball will simply be too much to overcome.

The topspin hitter should be pitched with hard stuff in. Once the hitter becomes aware of the ball in, then the pitcher can go away as the hitter will certainly try and adjust to the inside pitch. However, the topspin hitter has a major hole in his swing. The hole is up and in. As a pitcher, throwing up and in is the best way to exploit this flaw.

The higher you climb the ladder in baseball, the less topspin you see of the bat. Simply put- these players get exposed eventually. It's just a matter of time.
