(WSCR) The Cubs are cracking down on season ticket holders who excessively re-sell their tickets in secondary markets.

On Wednesday afternoon, the Cubs sent “non-renewal” letters to 40 season-ticket holders who the club believes are exploiting their tickets to make a profit on websites like Stubhub.

“After careful consideration,” the letter states, “we regret to inform you we have decided not to renew the license for your account. As a result, you will not be offered the opportunity to purchase season tickets for the 2013 season.”

The letter continues, “The Chicago Cubs are dedicated to ensuring Cubs games and other events at Wrigley Field remain available to as many fans as possible who are interested in enjoyable and memorable experiences. Your season ticket location will be reallocated and made available to fans at the top of our Season Ticket Waiting List.”

Cubs spokesperson Julian Green said these letters will have no affect on season-ticket holders who sell some or even most of their tickets in secondary markets.

“This is about making sure as many season tickets get in the hands of fans interested in enjoying Cubs baseball,” Green told Crain’s Chicago Business. “There are some account holders with objectives other than simply coming to Wrigley Field (for) the games.”

Terms disclosed to season-ticket holders express that season tickets “are a revocable license granted on a yearly basis at the sole discretion of the team.”
