barrysloateInteresting photo but tough call.
The man standing on the left with the striped socks, striped pants, and two tone hat (who dresses him in the morning?) looks more like a jockey. The two guys with the semi-bib fronts (not quite bibs) could reasonably be baseball players. But it looks like a mishmash of people from different walks of life and various sports.
No equipment, maybe two ballplayers, not an easy one and you can never be sure. Looks to be right around 1870.
Edited to add on a second look one of the so-called baseball players is holding a riding crop. This could be a group of jockeys.
