A man in a Colorado Rockies hat punched several women in the face in a crazy altercation outside of Coors Field over the weekend ... and TMZ Sports has obtained video of the brutality.
The incident went down shortly after the Rockies vs. Dodgers game in Denver on Friday -- just a few blocks away from the stadium -- when a man jumped into an altercation between women who appeared to be feuding with each other.
You can see in the footage, as several of the women were fighting -- the man stepped in and began unloading haymakers.
The guy punched several of the women in the face -- with one blow landing so flush, it appeared to knock one of the females out.
Later in the fight, the man punched another woman in the face while she was on the ground.
A police officer showed up and appeared to break up the scuffle, though it's unclear if any arrests were made. We've reached out to cops for comment, but so far, no word back yet.
As for what started the melee, it's not yet known ... but it was the Rockies' Opening Day and the home team did lose the game, 5-3, to their rival.
