Question from my friend Dice:

I'm trying to find out what % of all major league baseball players who ever played the game have hit at least one home run.  This would include, of course, pitchers and players who played just one game, or even had just one at bat (say he was called up from AAA just for the day and sucked and went back).

Someone quoted 28%, but, had no evidence to back it
up.

So, does anybody know where to get this info?
