Marco Antonio Rubio believes that Julio Cesar Chavez Jr has this thing in the bag if he can't score a knockout, but the sportsbooks aren't quite buying it. Chavez is the favorite, as expected, but not by a huge margin:
Chavez (44-0-1, 31 KO) is making his second defense of the WBC middleweight title. Rubio (53-5-1, 46 KO) would be picking up a career-best win and something close to a star-making win if he can pull off the upset.
