The Chicago White Sox are playing an actual MLB baseball game the Baltimore Orioles at Camden Yards in Baltimore today in a completely empty stadium due to the unrest over the death of Freddie Gray. Here are a few pictures that show the game happening to a crowd of no one. It looks like, well, what an empty stadium is supposed to look like.
Camden Yards has a seating capacity of 45,971. No one was in any of those seats. The only people at the stadium were the players, the umpires, a few scouts and the press (and perhaps a skeleton maintenance crew?). Basically, everyone can hear everything.
