Manny Pacquiao is embracing his underdog role as he comes out of retirement at 46 to challenge WBC welterweight champion Mario Barrios on Saturday at the MGM Grand. The Filipino legend, returning after four years, says he feels as motivated as ever and hopes to make history again. Barrios, 30, respects Pacquiao’s legacy but is determined to defend his title, calling him “just another opponent” in the ring. Pacquiao, an eight-division world champion and former senator, retired in 2021 after a storied 24-year career.
