“Nothing can hurt my arm. Last year, I pitched a 21-inning game for Peoria that took four hours. I never hurt my arm.” – Joe McGinnity
Joe McGinnity, one of the better pitchers around the turn of the 20th century, while with the National League’s Brooklyn franchise, set the Major League record for hitting batters with a pitch–with a total of 40 in 1900. These totals are since 1893. McGinnity also had a sidearm delivery which was difficult to control.
Pink Hawley had 5 different seasons in the dead ball era in which he had over 20 hit-by-pitches, as did Chick Fraser. Of course, with “small ball” the order of the day, batters tended to crowd the plate more than today.
Since WWII, only 2 pitchers have had over 20 hit-by-pitches; the California Angels’ Tom Murphy in 1969 and the Chicago Cubs’ Kerry Wood in 2003.
