I just found this thread and noticed something that I can't figure out: at 1:02 of the first video from game 1 in 1917, there's a shot of McGraw returning to the Giants' dugout. In the background, there's a black guy sitting with the Giants players in the dugout. It's hard to tell, but it looks like he's dressed in a bow tie. Anyone know who he might have been that he was allowed in the dugout with the players? 30 years before Jackie Robinson, I'm thinking there's no way could have been anything but an equipment manager.
