The bout is part of a packed day of boxing action. Fans will get to see Oleksandr Usyk take on Daniel Dubois, Bam Rodriguez face Phumelele Cafu, Sebastian Fundora square off against Tim Tszyu, and Isaac Cruz battle Omar Salcido.
Pacquiao's return has got people talking. At 46, he's aiming to claim the WBC welterweight championship belt. But the odds aren't in his favor. Bookmakers have him at +210, and most fans think Barrios will come out on top.
Friday's weigh-in added another layer of intrigue. Pacquiao tipped the scales 0.6 pounds heavier than Barrios and looked particularly strong. But the final face-off revealed a stunning height difference that could prove crucial.
Barrios stands six feet tall, towering over Pacquiao's 5-foot-5 frame. This height disadvantage could be a major hurdle for Pacquiao, especially considering his age and time away from the sport.
"Pacquiao's body looks more than ready," said one ringside observer. "But he's stepping in against an opponent with a lot of advantages. It won't be easy."
Despite the challenges, Pacquiao's return has boxing fans buzzing. Will the Filipino legend defy the odds once again? Or will Barrios' youth and size advantage prove too much? We'll find out on Saturday night.
