12:04 PM PT -- Major League Baseball is now weighing in on the issue ... saying it's launching an investigation into the allegations.
"Domestic violence is extraordinarily serious," the league said in a statement, "and everyone in baseball must use care to not engage in any behavior -- whether intentional or not -- that could be construed as minimizing the egregiousness of an act of domestic violence."
11:53 AM PT -- Brandon Taubmansays he is "deeply sorry and embarrassed" for the locker-room celebration incident involving a group of female reporters ... saying he wasn't trying to offend them.
"This past Saturday, during our clubhouse celebration, I used inappropriate language for which I am deeply sorry and embarrassed," Taubman said in a statement.
"My over-exuberance in support of a player has been misinterpreted as a demonstration of a regressive attitude about an important social issue."
"Those that know me know that I am a progressive and charitable member of the community, and a loving a committed husband and father."
"I hope that those who do not know me understand that the Sports Illustrated article does not reflect who I am or my values. I am sorry of anyone was offended by my actions."
A Houston Astros exec allegedly taunted a group of female reporters about a star player's domestic violence allegations ... but the team says that ain't exactly how it went down.
The man at the center of the controversy is assistant GM Brandon Taubman -- one of the top execs of the team -- who was reportedly fired up about star pitcher Roberto Osuna after their ALCS win Saturday night.
MLB suspended Osuna for 75 games and the Blue Jays, looking to get rid of his ass, traded Osuna to the Astros.
Fast-forward to Saturday night when Taubman ... Sports Illustrated cites a reporter (who was there) and several witnesses who say this happened during the locker room celebration.
"Taubman turned to a group of three female reporters, including one wearing a purple domestic-violence awareness bracelet, and yelled, half a dozen times, 'Thank God we got Osuna! I’m so f*cking glad we got Osuna!'"'
