They are announcing a sell out crowd for today with even SRO seats sold out. In the past the team has called a game sold out with several thousand seats below capacity listed as the official attendance, but in this case with the standing room tickets they might have actually sold as many as they did for the Philly games last year. Do we set the attendance record today? Or is the announced attendance significantly lower than official capacity? I say somewhere in the middle with just over 40K as the number.
Currently great tickets on StubHub are going for less than half of face value ($15 for 116 row CC which is a $50 ticket at full season prices before service charges), somehow I got lucky last night and sold a few extras for just under face value.
I'm not even bothering to list my last two available, I'll just sell them to a scalper at the game, if anyone wants them PM me on this site.
If the team gives away 1500 tickets, for example, in a stadium that seats 41,500, they will show "tickets sold" as 40,000. And MLB reports that number as "attendance". Then ESPN will look at the "attendance" of 40,000 out of 41,500 and report it as 96% of capacity. Teams now always report that tickets sold number.
A while ago (1980s?), one league reported tickets sold and the other reported a turnstile count which resulted in vastly different attendance figures. So, the league put their pointy heads together and decided to both report the higher number.
