Mikaela Mayer beat defiant Erica Farias to remain undefeated on Saturday in Las Vegas in her rise as one of the faces of women’s boxing in the United States.
Mayer defended her WBO super featherweight championship to stay on track for unification fights in a division that includes Briton Terri Harper as the WBC champion.
Former Olympian Mayer put on a disciplined and controlled performance to win her 15th consecutive fight, her first world title defense.
Farias is a former double-weight champion who was in her 18th world title fight and had shared a ring with Delfine Persoon, Cecilia Braekhus and Jessica McCaskill, which represented the most rigorous test of Mayer’s career until present.
Mayer let go of his hands in the fifth round from a distance, whipping a right hand down the middle that rocked Farias.
Farias made life difficult for Mayer in the sixth and seventh, her greater experience prompting her to take on the young champion.
Mayer was forced to dig in the final laps and she responded well, increasing her work rate and whipping up a series of hooks.
The judges all marked the fight in favor of Mayer (97-93, 98-92, 98-92).
The American will then turn to a unification fight for the title with Maiva Hamadouche, the IBF champion.
Harper, the WBC title holder and Hyun Mi Choi (WBA) are expected to meet later this year to bring the super featherweight division closer to an undisputed champion.
Vasiliy Lomachenko is live on Sky Sports in his comeback fight against Las Vegas’ Masayoshi Nakatani next weekend.
