Gamers have been thrilled to see a Fallout 4 mod starring slugger David Ortiz in a Boston Red Sox home jersey pop up on the Internet on Thursday, swinging a bloody, rusty nail-embedded baseball bat in a Beantown wasteland.

Well, Major League Baseball is calling foul ball.

"The use of these marks is an infringement of our rights. We plan to enforce those rights," an MLB spokesman wrote in an email Thursday to the Boston Globe.

The same newspaper reached out to the creative mind behind the Big Papi mod, Richie Branson, a Texas resident.

Branson says that if he hears from the league, he will "begrudgingly" remove the download.

"I'm not rich enough to even think about taking it to court," he told the Globe.

He did mention, however, that all he was aiming to do was add a missing element of Boston authenticity to Fallout 4 since the game is set in the city.

"Basically, I think it was the only thing missing from the game," Branson said. "You've got Fenway Park, the Green Monster, and all of Boston, but there weren't any Red Sox jerseys."

He added that he wasn't the first gamer or developer to make a modification and won't be the last.

"This is something that has been going on for years and years," he said. "People are non-commercially modifying games all the time."

It will be interesting to see exactly what kind of action the MLB takes here and how it could prevent future modifications from surfacing for popular video games like Fallout 4 in the future.
