Oakland has dedicated fans. They had 36k on Wednesday afternoon, a full sellout. The night before, Tuesday, about 30.6k, 87% capacity. And Monday night, the start of the most important series for the hometown club this season, a whopping 21k, 60% capacity.
October baseball cracks me up. Most stadiums are half-full during the season and then suddenly everyone is a die-hard fan, a lifelong supporter, got their team gear on, etc. The best show of this phenomena are the Marlins of 1997 and 2003.
