- Jermell Charlo scores 10th-round knockout over Argentinian
- Charlo becomes first ever four-belt super welterweight champ
Jermell Charlo had to exercise incredible patience during his quest to become the first undisputed super welterweight champion.
After a split draw in his first bout with Brian Castaño last year was followed by a three-month postponement of their rematch because of an injury for Castaño, Charlo had to wait again Saturday night because Castaño showed up late to the arena.
