Mayer, an undefeated star who just re-inked with Top Rank Boxing, her career-long promoter, is working towards her goal of getting all the straps at 130-pounds.
The scorecards — 100-90, 99-91 and 98-92 — did not do Hamadouche’s effort justice. Hamadouche, who had been champion for five years and six title defenses, landed 233 of 872 punches. Mayer was more accurate, landing 239 of 594 blows.
