For anyone considering catching the game Sunday, Astros tickets are super cheap on stubhub. I don't care if they are the worst team in baseball -- 40 bucks per for third base side dugout level seats ain't bad.
I received my OSU tickets last week but I think I'll wait until gameday to buy Astros tickets. I really don't think it's going to sell out before I get to Houston. I figure you can buy the cheapest ticket available and sit wherever you want.
