Barrios has lost some high-profile fights in his career, losing to both Gervonta "Tank" Davis and Keith Thurman. Despite those losses, Barrios went on to win the WBC interim welterweight title and was elevated to full champion shortly after.

Manny Pacquiao returns to the boxing ring for the first time in four years on Saturday to face Mario Barrios. The 46-year-old Pacquiao is understandably an underdog given his lack of recent time in the ring. WBC welterweight champion Barrios is 16 years younger than his opponent and has fought five more times than him over the last four years.
