Who said “hit ’em where they aint?”

The phrase “hit ’em where they aint” was the simple hitting advice of Willie Keeler. Keeler did a good job of hitting it where they weren’t, becoming one of the best hitters of his era by using a choked-up batting stance to punch singles over infielder’s heads. He finished his career with a .345 average, and hit an incredible .432 in 1897, the third-highest in major league history.
