"Why is it when there's an injury from a ball hit from a non-wood bat, people blame the bat?" asks Jim Darby of Easton Sports, a leading bat manufacturer. "When there's an injury from a ball off a wood bat, people say that's part of the game."

Either way it is part of the game. Most of life has inherent risks. A life without risks would not be worth living.

The argument is that a line drive struck off of an aluminum bat travels much faster than one from a wooden bat, with the result that some balls will head toward the pitcher at a speed impossible for him to avoid. Human reaction time, even to the degree possessed by an athlete, is not quick enough to allow the pitcher to duck or turn out of the way. Thus, if you use aluminum bats, pitchers will be hit by balls, and hit hard. Some will be injured; some will die. It’s okay with me if baseball allows aluminum bats — I’m a boxing fan and I favor lightweight gloves — it's just that you need to be clear about the trade off: it’s the certainty of an occasional injury and, or on some occasions, death.
