Jermell Charlo earned a stoppage victory over Brian Castano II for the undisputed super welterweight title.
With the win, live on Showtime, Charlo became the first male undisputed super welterweight champion.
The card also featured Jaron Ennis earning a victory over Custio Clayton and Kevin Gonzalez besting Emanuel Rivera.
The end came when Charlo (35-1-1, 18 KOs) dropped Castaño with a short, left hook as he was fighting off the ropes with around a minute left in the tenth. Castaño (17-1-2, 12 KOs) rose on unsteady legs and was allowed to continue and Charlo jumped on him, landing a vicious left to the head and body that caused Castaño to collapse and referee Jerry Cantu to wave off the bout at 2:33 of the tenth.
“This is legacy,” Charlo said in the ring afterward. “This is something that is legendary. I’m a legend. I knew Castaño was going to give it his all. I knew I had trained very, very hard but you all can see that I came in at 152 pounds because I was really in shape, and I wanted to make sure that this was my fight.
“I don’t care about being late. I don’t care about who’s early. I knew once I got to this arena, and I’m fighting outside in this beautiful place, I had to get it on.”
