is it possible that the marlins could set a low-attendance record?
Perhaps if some sort of 'modern-era' cut-off could be devised they might threaten a record, but back in the 1930's the old St Louis Browns (now the AngelO's) failed to hit the 100,000 mark -
for the entire season - in three different seasons. (Marlins' aggregate attendance this season through seven home fixtures to date is 137,776.)
Actually on the radio it sounded like a decent group in there (announced attendance was 15,933) - maybe having the roof closed creates a lot of reverb.
