Jermell Charlo and Brian Castagno had a second fight, and it lasted 9.5 rounds out of the planned 12. And then Charlo finished the opponent and became the absolute champion.
If the first fight a year ago ended with Charlo winning a split decision, now he knocked out Castaño in the 10th round in the Showtime main event.
Jermell Charlo of Houston has a record of 35-1-1, 19 KOs, and has completely unified the 154-pound belt. Charlo defended his IBF, WBA and WBC titles and took the WBO belt from Castaño, who lost for the first time in his nine-year professional career (17-1-2, 12 KOs).
Charlo also joined Bernard Hopkins, Jermain Taylor, Terence Crawford, Josh Taylor, Oleksandr Usyk and Canelo Alvarez as one of the seven undisputed champions since boxing began recognizing four organizations.
Charlo was ahead on all three judges’ scorecards (89–82, 88–83 and 87–84) before the 10th round.
