White Sox fans who purchased tickets to an event in June were sent another email promoting an event in September, but the email list had not been placed in the BBC field, exposing the private email addresses of 200 ticket buyers.

Those who had purchased tickets to the “Sox Crawl” on June 15 received the email promoting the same event later this year, set to take place on September 28. One ticket purchaser reached out to the Chicago team for an explanation. According to the Chicago Sun Times, the Sox’ ticket sales coordinator said the team “made a huge mistake and are very sorry” for not setting the email to BBC.

The Sox released a statement on Friday addressing the situation.

“Unfortunately, an email was sent to a group of past purchasers that mistakenly shared personal email address information,” the statement read. “We deeply regret the error, and are working with fans to address concerns. We take the privacy and security of our fans’ personal information very seriously and are working internally to ensure that this does not happen again.”

The Sox will face the Washington Nationals today and tomorrow, followed by the New York Yankees on Thursday.
