Since 1900 the most times an American League pitcher struck out during a single season was sixty-five times set in 1972 by Wilbur Wood of the Chicago White Sox. In the National League it was sixty-two times set in 1968 by Jerry Koosman of the New York Mets.
Reggie Jackson, the all-time strikeout leader, also holds the Major League record for most seasons with at least one-hundred strikeouts — he has eighteen.
Did you know that from 1952 through 1962 Nellie Fox led the league in fewest strikeouts for a player appearing in at least one-hundred fifty games?
