Century mark

For my story in Wednesday's Times, I interviewed several coaches, parents and pitchers about pitch counts for high school pitchers.

And something kept coming up. The number 100.

It's a round number. It's even. Easy to relate something to or against.

But why 100? Why not something like, oh I don't know, 50?

I guess it's just another in the litany of figures that make up the numerically enjoyable game of baseball.
