 Anson relented and the game went on with Walker in the Toledo lineup, but in an 1884 game against Toledo, by now affiliated with the AA and playing as the Mudhens, Anson held his line and insisted that the arrangements for the game include a provision excluding black players from both teams' lineups.By the 1897 season, the leagues adopted an agreement that neither they nor their minor-league affiliates would admit black players, establishing a racial barrier in professional baseball for the next half-century.A post-season "World's Championship Series" had been held in 1884 between the champions of the League (Providence) and the Association (Metropolitan), and the White Stockings and the Browns arranged to continue that new tradition in 1885.
