In fenways defense , the tickets are "sold" ... To either ace tickets or one of the other 20 something ticketing agencies that have their hands in their... And I've stood in the gameday ticket line for tickets to both a blue jay and oriole gm, and they definitely sold every available GD they had those days ( I was in the 1st 10 or so people each time, but the line was 2-300 deep each time easily )...
I've yet to be to a high profile gm-Yankees,rangers etc.. ( that will change this yr!!! ) but even the bluejays and orioles gms I've been too, as I'm sure you guys can attest to also, yeah there's some empty seats until about the 2nd inning , but they quickly fill up to the point where you have to strain to find empty seats... I've only been to a handful of gms since I've moved, but from my experiences the sox def "sold out" the gms I've been too...
