4. Sandy Koufax
If Sandy Koufax’s career was not cut short due to arthritis in his pitching elbow, he could have been even higher on this list. Koufax had a run from 1961 through 1966 in which he led the league in strikeouts four times, wins three times, and ERA five times. He won the Triple Crown and Cy Young Awards three times as well. Koufax’s success was not just individual either, as the Dodgers won four World Series titles with him leading the charge.
