With it being not just the final regular season meeting but also an afternoon fixture, they'll move heaven and earth to get this one in if there's the slightest possibility - back in 2004 I sat out a 3hr 42min rain delay at a Yankees-Angels Saturday afternoon match (in August, final head-to-head series of season).
The old Yankee Stadium (sadly that was my only visit there ever) had the best beer selection I've ever seen at a sports arena - one had to exercise maximum discipline to avoid succumbing to further and further temptation as the rain delay dragged on.
