Shane Mosley Jr. just proved he belongs within the ranks of the elite. The son of the Hall of Famer pulled off a stunning sixth-round TKO win over the former WBC interim 154-pound champion in his Zuffa Boxing debut . As the son of one of the greatest 135 to 147-pound boxers of all time, Mosley Jr. has always had high expectations he repeatedly failed to meet. That included his 12-round loss to Jesus Ramos for the WBC interim middleweight title in his most recent outing before signing with Zuffa Boxing.
