Puzzling Find

Isn't this a bit like the USA Basketball dream team a la Bird, Magic, Jordan celebrating a win over team Bangladesh? I always assumed that any sports team playing a philadelphia based opponent all but declared victory weeks beforehand. Do such games even count in the standings? Anyhow, this fella seems oddly excited about beating the philadelphia baseball team in a game. I've never seen anything like it--I wonder if the game had some sort of actual meaning?
