There are few pitchers that come out of the shoot being TOR starters.
Look at Cliff Lee (30 years old). How about Cris Carpenter (29)?
Or how about:
Wainwright (26, though it could be argued his first TOR was last year, at age 28)
Josh Johnson (25)
Randy Johnson (27, though he was 29 when he had his first TOR year)
Homer Bailey is 24, with TOR potential stuff. Give him time to realize it.
