Ex-Twins infielder Danny Valencia apparently laid the smack down on his teammate Billy Butler on Friday night.
According to the San Francisco Chronicle, Butler missed both of the Oakland Athletics' weekend games after getting into a clubhouse fight with Valencia after Friday's game.
Why? The Chronicle says Butler told on Valencia for not wearing the baseball cleats he was supposed to be wearing per an agreement with a representative.
Meanwhile, the Athletics aren't talking about it, only saying that Butler missed Sunday's game because of vomiting and nausea. As Deadspin notes, those are common symptoms of a concussion. But that's pure speculation on Deadspin's part.
