The matchup is scheduled for 12 rounds and has drawn a tremendous amount of attention for various reasons.Pacquiao, one of the greatest boxers of all time, is playing an all too familiar role: an aging fighter who just can't stick to retirement. With a record of 62-8-2, 39 knockouts/TKOs, and the mythical status of an 8-division world champion, Pacquiao is the envy of many boxers, but he is still 46 years old.He hasn't competed professionally since a 2021 loss to Yordenis Ugás, and has only fought twice, in exhibition bouts, since his retirement. Meanwhile, Barrios enters the ring 16 years Pacquiao's junior. He holds the WBC welterweight title they'll be competing for, and is 29-2-1, with 18 stoppages.So, despite Pacquiao's legend, he isn't expected to win. Not at 46 years old, and this is reflected by the betting odds, with DraftKings Sportsbook listing Barrios as a -275 favorite, while Pacquiao himself is a +210 underdog.
