Baseball is known as 'America's National Pastime' ... but in Canada it looks more like a rerun of the Jerry Springer show.
Check out this video, obtained by TMZ, showing 2 women getting into a free-for-all with others in the nosebleed section of Rogers Centre in Toronto last night.
As the L.A. Angels were routing the Blue Jays 12-0, the women started going at it after they got into some sort of nasty argument. Over what? We don't know.
But our sources tell us one of the women, who was sitting in her seat watching the game, had her hair pulled by the other woman from behind.
