This post does the same thing with starting pitchers, except it will be a top forty instead of a top ten list as there is a much large pool of pitchers than of players at any position. Pitchers are more difficult to rank because their roles have changed dramatically over the decades. In the first part of of the 20th century, pitchers were expected to finish what they started and thus threw a lot more complete games than they do now. Up until the 1920s, more than half the games were complete games. The percentage of complete games decreased gradually over the decades, but was still over 25% in the 1970s.
