I was just looking at past stats, and came across George Bradley.  George pitched just 9 years, and threw the 1st recorded No-Hitter, but check out this guys rookie season!  

He started 60 games, threw over 500+ innings, and had an era of just 2.05...I thought that with the recent talk of rushing young arms to the majors (Hurley, Harrison, etc.), this was ammusing.  They really didn't care about age, pitch count, over-use, 5 days rest, or any of that then.  Oh, how things change...of course, pitchers are also throwing for  12-15yrs in the bigs now, compared to 5-10.  Anyhow, check it out and enjoy:
