File this under the “oops!” heading.

Fans of the New York Mets, Washington Nationals and Chicago Cubs on Monday were the recipients of marketing e-mails from StubHub for playoff tickets, despite the fact that neither team qualified for the playoffs long before the baseball regular season ended.

“Be there alongside your New York Mets as they chase baseball immortality. Go to StubHub, where you’ll find a fantastic selection of tickets to every playoff game – so you experience the championship chase live and in person. Check it out. Go to StubHub and get the seats you want today,” the Mets e-mail said, but the other teams had the same message.

Only four teams remain in the baseball playoff picture, the New York Yankees, Philadelphia Phillies, Los Angeles Angels and the Los Angeles Dodgers.

Of the three teams from the erroneous e-mails, only the Cubs finished the regular season with more than 80 wins, but they were well behind the league’s eventual playoff teams. StubHub, the world’s largest secondary ticketing company, and the second-largest overall ticketing company behind rival Ticketmaster according to TicketNews’s exclusive industry rankings, said mistaken e-mails were the result of an “e-mail glitch,” which the company did not describe.

“This was due to an e-mail glitch. We regret the error and apologize for any inconvenience or confusion this may have caused,” StubHub spokesperson Joellen Ferrer said in a statement. “Follow-up e-mails will be sent to every person that received the e-mail, notifying them of the error on our part. In no way does this affect any transactions that have taken place on StubHub.”
