MLB champions are World Series champions, not world champions, named after a series originally sponsored by the New York World newspaper. Also the Toronto Blue Jays are not an American team.

At least if someone brushes up against baseball players, they don't fall down clutching their knees to their chests crying like little girls until a penalty is awarded and then jump up laughing. Try that in baseball and you'd be asking for a fastball to the ribcage. In hockey the opposing team wouldn't even have to do anything. The referee would call a penalty for unsportsmanlike conduct.
