Overview
- Mayer won by unanimous decision with scores of 100-90, 98-92, and 98-92 in Montreal.
- The fight headlined a Top Rank card at Casino de Montreal for Spencer’s WBA title and the vacant WBC and WBO belts.
- Spencer, a decorated Canadian amateur and the naturally bigger fighter, struggled to cope with Mayer’s pace and pressure.
- The WBC and WBO titles were vacant after Cecilia Braekhus retired, creating the three-belt opportunity.
- Already holding the WBO welterweight crown, Mayer was promptly targeted by unified 147lb champion Lauren Price, who called for an undisputed matchup next year.
