One might think Major League pitchers should know better than to tip their pitches. After all, they’re the best of the best. But Major League pitchers are actually more likely to tip than even high-school pitchers or Little Leaguers. This is because less experienced pitchers aren’t likely to have thrown enough pitches to have ingrained consistent mechanics, whereas major leaguers throw thousands of pitches each year in the bullpen to recreate the same deliveries over and over.
