Number on the bottom of the knob of a baseball bat?

[Comp625]

I was browsing through wooden baseball bat at Sports Authority today and I saw some heavy bats. They were 32 inches and had a number at the knob of the bat. The number of the bat that I was looking at was 4. What does this number represent? The number is carved into the knob of the bat.

i'd guess 34 .. only cuz i owned a 33 inch bat that had a 3

Of all the bats I've ever had, the single digit on the knob corresponded to the length. If you're absolutely positive it's a 32 inch and not a 34, then I'd guess it refers to a 34 oz weight.

34oz is a heavy ass bat. All my bats are 33 and 34 inches and none of them exceed 26 oz. Then again theyre all aluminum and $100+ each........

The 4 is definitely the length (34").
