Two Oakland A's players got into a scuffle before the team's batting practice last Friday, and new details emerging from the clubhouse indicate that the fight all started over a sneaker endorsement.

According to San Francisco Chronicle, the brawl between A's third baseman Danny Valencia and designated hitter Billy Butler began after an equipment representative asked Valencia about a pair of off-brand cleats that he had previously been told not to wear.

Valencia, a Nike athlete, has been known to wear converted Air Jordan customs during games, and has posted Yeezy Boosts on his Instagram a few times. It's also possible that the rep was telling Valencia not to wear his converted Kobe cleats (pictured below), which players like San Francisco's Hunter Pence and Angel Pagan have been injured in.

Team sources say that Valencia told the rep that he only wore the off-brand cleats during pregame workouts, however Butler reportedly interjected and told the rep that Valencia was lying.

"Don't you ever loud-talk me in front of a rep. That was wrong," Valencia reportedly told Butler, who responded by taunting Valencia before the fight broke out.

While clubhouse brawls amongst teammates aren't unheard of, this has to be one of the more bizarre dugout disagreements.
