The trick is to pick up the spin. Some pitchers vary their delivery slightly, unintentionally signaling a curve. The 5-ounce leather covered baseball is traveling at 90 mph, but with experience, you stay in the batter’s box, confident you can predict the trajectory, and either hit or dodge the pitch.
But no matter how good you think you are – you often fail. Sometimes you swing and miss; sometimes the ball hits you in the head. Either way, it hurts.
