Baseball hitting coaches love to say, “Hitting is hard.” I’m here to tell you that hitting isn’t hard. It’s impossible. Human vision can’t track any pitch over about 83 miles-per-hour (134 kph) to the bat. Getting square contact on a round ball with a round bat gives no more than a one-inch (2.5 cm) margin of error. High-level pitches not only travel at speeds up to 100 miles-per-hour (160 kph) but also move in unpredictable ways due to gravity, spin, Magnus effect, and other forces. It’s hard to argue with Ted Williams’ (the last major leaguer to hit .400) claim that hitting is “the most difficult thing in sport.”
So how do skilled batters not only hit well-pitched baseballs but also hit them very hard and very far? It’s all workarounds. Hitters and hitting coaches relentlessly work on swing mechanics to generate bat speed and attack angles necessary to drive the ball. But they all will tell you that mechanics mean little without good timing to deliver the barrel of the bat to the ball at the optimal time and place in the hitting zone.
So, where does timing come from? Stance and swing mechanics help hitters get two eyes on the pitcher, minimize head movement, get their front foot down “on time,” and launch their swings in synch with the pitcher’s motion. But timing also involves pitch recognition. Good swing mechanics maximize the amount of time (and milliseconds matter) that hitters have to shut down their swing, if needed, or to make in-swing adjustments that get the barrel of the bat to the ball.
