In any case, there are so many other things that come into play in this comparison. Would anyone really want an injury-prone pitcher like Wood over a guy that never gets injured like Buehrle? You can have all the best stuff in baseball but if you aren't even pitching, what good is it?

It's less because of pinch-hitters.

 

But does it matter?  If the DH in the A.L. doesn't affect pitchers, why do most baseball analysts say that there is around a 1 run difference in pitchers' ERAs when going from the N.L. to the A.L.?

 

I think I read that usually a pitcher faces another pitcher in the NL maybe twice per game. Once a reliever's turn to hit comes up, usually he gets yanked for a pinch hitter. So, it doesn't factor into it that much.

It's impossible to compare the 2 at this point in their careers. Like I said, I get a feeling that 5 years from now, Mark will prove to clearly be the better pitcher.
