You're about 750 tickets too high. UL doesn't sell season tickets for every seat in the stadium. Jay Walker posted an article talking about where the 750 or so tickets between the season ticket sold number and the Tigue capacity number goes towards.
Not all of the tickets from that block will be "sold" for every game. What isn't sold will be sold to an individual who walks up and purchases a ticket. Anything over 3,750 will be sold as SRO. But I guarantee that anyone who bought a SRO ticket this past weekend will end up being able to purchase an actual seat for a future game, meaning attendance will be less than what it was this weekend. Unless the team goes on a run to start the season, then throw what I said out of the window.A block of tickets is reserved each game for UL students, MLB scouts, families of UL players and staff, families of the visiting team and tickets for fans of the visitors and tickets for those folks who buy the outfield signs at "The Tigue".
