Toledo, without Tony Mullane, played the Browns on May 6, in the second game of the series. The Globe noted something unique about the game:
About 600 persons witnessed the game, which was interesting and at times remarkably brilliant...Among the spectators there were quite a number of colored individuals, attracted by the announcement that Walker, the colored catcher, would appear behind the bat for the visitors. They were enthusiastic over Walker, and manifested decided partiality for his club.-St. Louis Globe-Democrat, May 7, 1884
While the Browns won the game 6-3, I think this game may have deeper significance. To the best of my knowledge, I think Fleet Walker's appearance for Toledo represents the first time that an African-American played in a major league baseball game in St. Louis.
