I suppose, to be slightly fairer in the comparison, the opener last season was against division rival Toronto and in late March there are still a lot of Canadian snow birds in Florida, whereas I doubt there are many Rockies fans in central Florida for this series. By the time Texas showed up for a series at the beginning of April, Rays attendance had already fallen to their season average of around 14,000. So, 8,000-10,000 might indeed be their core fanbase.
