No naming rights, at least on these jerseys

There's no such thing as freedom of speech when it comes to buying personalized jerseys from MLB.com. There you can get A-Rod's No. 13 jersey with almost anything you like on it, but don't ask for A-Fraud. That's a no-no.

Any fan hoping to make fun of New York Yankees third baseman Alex Rodriguez can no longer get a No. 13 Yankees jersey with the word "A-Fraud" on the back.

MLB.com has banned the new A-Rod nickname from the personalization feature on replica jerseys on MLB.com. MLB.com spokesman Matt Gould told CNBC that the league does not allow fans to personalize products with anything that is deemed inappropriate, derogatory or profane.

Fans haven't been able to personalize their jerseys on the site with the word "steroids" since 2005, but as of this afternoon, fans can get A-Rod's drug of choice, "Boli," on the back of jerseys. They can also get "Sucart," the last name of A-Rod's cousin, who has been part of the story.

Here's guessing "Boli" and "Sucart" won't draw nearly the interested that A-Fraud was getting.
