Colby Jack was signed by the Athletics off the campus of Colby College in Maine.
On September 1, 1906, he pitched 24 innings to set an AL record tied only by his
opponent that day, Boston's Joe Harris
. Coombs's 13 shutouts in 1910 are an AL record.
His 31 wins led the league that season, and he added three more victories in the
against the Cubs. Coombs was unbeaten in WS competition, winning another
game in 1911 and one more for Wilbert Robinson's 1916 Brooklyn Dodgers
. Coombs became
a championship-winning coach at Duke University who sent many players to the majors.
