Julio Cesar Chavez Jr was once a top contender, and even a good champion. In 2011, he won his 43rd contest and captured the WBC world middleweight title from the previously unbeaten Sebastian Zbik. He would then make 3 consecutive defences before taking on Sergio Martinez, and losing.
In the fight with Martinez he went in with a record of 46-0-1 but was really dominated in the fight. Martinez was simply the better man in every department and the only thing that went Chavez Jr’s was a knockdown in the twelfth round.
