About: Ernie Koob

Ernest Gerald Koob (September 11, 1892 – November 12, 1941), was a professional baseball player who played pitcher in the Major Leagues from 1915 to 1919 for the St. Louis Browns. On May 5, 1917, Koob no-hit the eventual World Champion Chicago White Sox 1-0, besting Eddie Cicotte—himself a no-hit pitcher against the Browns less than a month earlier, on April 14. The very next day, his teammate Bob Groom also no-hit the White Sox, 3–0 in the second game of a doubleheader; to date, Koob and Groom are the only teammates to pitch no-hitters on consecutive days.
