MLB Investigators: Padres Gay Chorus Incident Was 'Human Error'

MLB investigators have determined there was NO malicious intent to cut the mics on the Gay Men's Chorus before the Padres game last weekend ... chalking the whole thing up to "human error."

The San Diego Gay Men's Chorus was supposed to perform the National Anthem before Saturday's game -- but when they began to sing, a woman's voice came over the P.A. system and drowned them out.

MLB investigated to see if foul play was involved ... but officials say the whole thing was just one big accidental screw-up.

In fact, investigators point out -- "the situation was exacerbated by the fact that the lead entertainment supervisor was involved in a car accident on Friday night and thus was unable to work on Saturday."

The staffers who covered for the injured supervisor "were insufficiently familiar" with their duties and screwed up -- but "employees involved had no malicious intentions."

MLB says the staffers have "universally relayed contrition for how the incident unfolded and the adverse impression that it created."
