A rogue Major League Baseball Facebook page administrator posted offensive status updates on the pages of nine teams Thursday, including the San Francisco Giants, according to the social network.

On Thursday afternoon, a status update from the official Facebook page of the San Francisco Giants said "Wow, that Chik-Fil-A guy sure is an [expletive]," a reference to the owner of the fast-food franchise, who recently stirred up controversy with vocal opposition to same-sex marriage.

A Facebook spokesperson told the tech blog TechCrunch that the updates were the work of a single person with access to all of the accounts.

"Recently, several Pages made unauthorized posts as a result of actions from a single rogue administrator of these Pages. Our team responded quickly and worked with our partners to eliminate the spam caused by this attack. This was an unique, isolated incident and we are always working to improve our systems to better protect our users and their data," the spokesperson for the Menlo Park company said.

The New York Yankees account was the first to be affected, when it proclaimed that star shortstop Derek Jeter would miss the rest of the season due to "sexual reassignment surgery," adding that he would return "stronger than ever in 2013 as Minnie Mantlez." Other teams affected included the Chicago Cubs, whose status attacked the team's most famous fan, comedic actor Bill Murray; the Chicago White Sox, President Barack Obama's favorite team, proclaimed it was voting for Mitt Romney in the upcoming election; the Washington Nationals, which said the team was moving back to its former home of Montreal; the Miami Marlins, which promised "FREE PITBULL NIGHT at Marlins Park;" the Atlanta Braves, which made a reference to retiring star Chipper Jones' effect on female fans; the Los Angeles Angels of Anaheim, which made reference to an attractive female fan; and the San Diego Padres, which "STRONGLY DISCOURAGED" disabled fans from attending games.

Major League Baseball issued a statement Thursday afternoon on the offensive status updates.

"For a brief moment today, a few MLB Club Facebook accounts were hacked and inappropriate material was briefly on display from those Clubs' pages on Facebook. MLB Advanced Media oversees these Facebook pages on behalf of the Clubs and regrets this occurrence. We are working with Facebook, Major League Baseball Security and, where appropriate, legal authorities to determine the circumstances surrounding this situation," the statement read.

A Giants spokeswoman declined to comment.
