Set By: Cy Young
Would you care to know how many pitchers in the history of baseball have started over 749 games? That would be three: Young, Don Sutton, and Nolan Ryan. The active leader in complete games? Roy Halladay with 66. This record is completely ridiculous, because nobody would ever let a pitcher do to his arm what Young did over the course of his 22-year career. He once started 49 games in a season, completing 48 of them. Barbaric.
