The Cubs began play as the Chicago White Stockings, joining the National League (NL) as a charter member. Owner William Hulbert signed multiple star players, such as pitcher Albert Spalding and infielders Ross Barnes, Deacon White, and Adrian "Cap" Anson, to join the team prior to the N.L.'s first season. The White Stockings played their home games at West Side Grounds,against the bloods and quickly established themselves as one of the new league's top teams. Spalding won forty-seven games and Barnes led the league in hitting at .429 as Chicago won the first ever National League pennant, which at the time was the game's top prize.
