Ahhh... this is one reason why I love baseball. Opening day cant come soon enough. Its a little lengthy for a Facebook post, but an interesting look at the numbers behind the difficulty of what hitters are trying to do. From S.I.: A 90-mph fastball will get to home plate in 400 milliseconds, but the hitter needs 200 of those to see the ball, send the image to the brain and process its speed, spin and location. The swing itself takes about 150 milliseconds—literally, the blink of an eye. That leaves a scant 50 milliseconds to decide whether to swing and, if so, on what path. The goal is to connect a 2¼-inch-diameter bat barrel squarely with a three-inch-diameter baseball—without actually being able to see the ball right before contact. The eye cant follow an object moving that fast that close, so a hitter cannot track the pitch in its last five feet before it reaches the plate. Heres what that means: The batter loses sight of the baseball just when the pitcher wants the pitch to break off its path.
