Banc of California Stadium - Super lightweight contender Arnold Barboza Jr. (22-0, 9 KOs) dished out a sustained beating to Ricky Sismundo, and Sismundo's corner stopped the bout following the conclusion of the fourth round.
Now Barboza wants a world title shot - and he doesn't care if it's Jose Ramirez, Regis Prograis or Josh Taylor. Ramirez, like Barboza, is promoted by Top Rank - while Prograis and Taylor are slated to collide in the final bout of the World Boxing Super Series.
"I want a world title shot now," Barboza said. "I want to challenge all the champions. It doesn't matter who it is, or where it takes place. All I want is to face Ramirez, Prograis, or Taylor, and I want it now!"
Also on the card, welterweight contender Chris van Heerden (28-2-1, 12 KOs) continued his march up the rankings, overcoming a bad a cut to defeat Aslanbek Kozaev (33-3-1, 8 KOs) via eight-round unanimous decision (79-73 2x and 78-74). van Heerden has won five straight since a 2015 defeat to Errol Spence Jr.
Former junior featherweight world champion Jessie Magdaleno is ready to take on the featherweight titans. In his second bout since moving up in weight, Magdaleno scored a ninth-round technical decision over Rafael Rivera after an elbow opened up a gash on the bridge of Magdaleno's nose.
Magdaleno knocked down Rivera early in the ninth round and prevailed by scores of 89-81, 89-81 and 88-82.
Emanuel Navarrete was already a champion. He is now one of the sport's elite. Navarrete knocked out the previously unbeaten Francisco "Panchito" De Vaca in three rounds Saturday evening.
Navarrete (28-1, 24 KOs), who upset Isaac Dogboe to win the title and then defeated him in an immediate rematch, knocked down De Vaca (20-1, 6 KOs) in the second round and forced the referee to stop the fight after dishing out a sustained beating in the third.
