@formerdirtdart sent this in. As the king of fairness I am happy to share this with you.
These numbers are unofficial but to my eye seem right. As always I leave it to you to decide if the site is accurate. Here’s Walt (@formerdirtdart):
Gleamed from the reported attendance (sold tickets), the Mets ticket sales for 2011 opening series were better this year, than last, and out did first weekend series too.
The Mets 2011 season home opening (1st weekend too) series, three games vs the Nationals (Fri, Sat, Sun), sold 107,928 tickets (avg 35,976 per gm).
Last seasons home opening series, three games vs the Marlins (Mon, Wed, Thur), sold 106,090 tickets (avg 35,363 per gm).
The first home weekend series, three games vs the Nationals (Fri, Sat, Sun), sold 94,771 tickets (avg 31,590 per gm).
Gangbusters!
