a baseball bat ?

Whose bat?
There are no restrictions to the weight of a bat used by a major league batter. However, the bat may be no longer than 42 inches.

Anytime that you have -2 or -any number, all it means is that you subtract that amount from the length of the bat; and it'll tell you how heavy the bat is. Let's say you have a 33" bat and it says -10, that means that the bat is 23 oz.
