The debate of the day on ESPN radio after the Rocket was the 8th pitcher to reach 350 wins (first in over 40 years). On the other hand there has been only 3 hitters reach 700 HR (Bonds, Aaron, and Ruth).

Lots of power hitters and ways to artificially bulk yourself up.

It is much harder to get around the five-man rotation, in a 4-man rotation a pitcher got the start 40 times, with 5-man rotation, said pitcher only gets the ball 32-33 times.

That, and relief pitching has evolved beyond giving Hoyt or Rollie the ball in the 7th and telling him to finish the game out.
