Because they need to be printed and mailed ahead of time, tickets for teams that will be going to the playoffs or expect to make the playoffs are often never used. The Mets, in the running for a Wild Card spot did that. They played the Wild Card game at Citi Field, but alas, they lost, so the tickets we have for the division and league championship series and these for the World Series will never be used. Hopefully, next year, they'll be back in the World Series. But for this year, I hope the Cubs win it.
