As a rookie, Harry Coveleskie defeated John McGraw's New York ballclub three times in five days, earning him the nickname "The Giant Killer." After his career was over, he opened a bar in Pennsylvania by that same name.
Coveleskie refused to pitch against his younger brother Stan. The two only appeared in the same game once, in 1916 when Stan started for the Indians against Harry's Tigers and was knocked out in the first inning. Harry pitched in relief for Detroit.
