The rumors heading into the Copa America Centenario were that ticket prices were sky high and that we'd see a lot of empty seats. Both have ended up being true, but it's hard to call the tournament a flop. The empty seats have been seen at the less desirable matches while for the most part, all the important matches have either sold out come close.

The United States' semifinal match-up against No. 1 ranked Argentina is no exception. Tournament organizers announced on Monday evening that NRG Stadium in Houston has officially sold out. 70,000+ (Google claims 71,500 is actual capacity) will fill the place tomorrow night as the Americans attempt to knock off Lionel Messi and his bunch of world-class friends.

Tickets are still extremely high. The average price for a ticket to this match was reportedly in excess of $200. That apparently hasn't stopped the fans from breaking out the cash to see their favorite team and/or players.

Seattle sold 47,322 tickets for the quarterfinal against Ecuador. It's not too surprising to see this match sell out considering it's got the host nation and the main talent attraction all in one match-up.

It should be a wild night tomorrow that will only be made more exciting by a capacity crowd.
