Most Wins In A Season

Jack Chesbro

“By midseason (1904) he was able to signal to his catcher just how far the ball was going to drop and later admitted, ‘Over the last 30 games of the season I pitched spitballs entirely. In those 30 games I didn’t pitch a half-dozen balls that weren’t spitballs.” – Glenn Stout in Yankees Century (2002)


“Happy Jack” Chesbro holds the record, starting in 1893, for most wins in a season with 41, achieved in 1904 with the New York Highlanders (their name was changed to the Yankees in 1913).

The only other pitcher with 40 wins in a season is “Big Ed” Walsh of the Chicago White Sox who chalked up 40 victories in 1908. The great Christy Mathewson of the New York Giants has the third highest wins in a season with 37, recorded in 1908.

Since WWII, Denny McLain, with the Detroit Tigers in 1968 won 31 decisions, while the Philadelphia Phillies’ Robin Roberts won 28 games in 1952.
