The Louisville Grays were a 19th century U.S. baseball team and charter member of the National League, based in Louisville, Kentucky. They played two seasons, 1876 and 1877, and compiled a record of 65–61. The Grays were undone by major league baseball's first gambling scandal. The team was in first place in August 1877, then suddenly lost seven games and tied one against the Boston Red Stockings and Hartford Dark Blues. Boston ended up winning the pennant, seven games ahead of the second-place Grays. (See the linked standings and game logs.)
