Current Through 2008 Season


Trivia alert: Cy Young, who is the all time career leader in innings pitched and the only pitcher in history with seven-thousand plus innings to his name, does not appear on this chart of the top one-hundred single season leaders.

Since 1980 no pitcher has thrown more than three-hundred innings during a single season and the modern average for starting pitchers is roughly two-hundred four innings pitched per regular season.

Did you know that only a handful of these pitchers even appeared in a single game during the twentieth century and no pitcher from the twenty-first century even cracked the top 500?
