This afternoon the Comptons and the Union Blues play a game at the Union Grounds for the benefit of the Woman's Exchange...Among the interesting features in the game will be the first appearance in St. Louis of Tom Ryder, the St. Louis Union's new man, who will play at the left field for the Blues.-St. Louis Globe-Democrat, July 19, 1884
Thomas Ryder of Dubuque played eight games in the major leagues, all with the Maroons in 1884. He also got into several games with the Union Blues. B-Ref lists his first game with the big club as being on July 22 and I'll keep an eye out for that. The quick search that I did didn't show him playing with the Maroons until they got back from their road trip but I just probably missed the earlier game. I did see him playing a couple of games with the Union Blues in late July and I just figured he didn't join the team until after the big road trip. We'll see.
