Mikaela Mayer Becomes Three-Division World Champion

Mikaela Mayer outpointed hometown favourite Mary Spencer by unanimous decision in Montreal to claim the WBA and the vacant WBC and WBO super‑welterweight (light‑middleweight) titles, with judges scoring 100-90, 98-92 and 98-92. The 35-year-old dominated across 10 rounds at Casino de Montreal — walking Spencer down behind a sharp jab, landing hooks to the head and body and leaving Spencer bloodied. The victory adds to Mayer’s WBO welterweight crown and cements her as a three-division world champion (super‑featherweight, welterweight and light‑middleweight), improving her record to 22-2. Mayer said the win gives her options: pursue undisputed status at 154 pounds, where the IBF belt is held by Oshae Jones, or return to welterweight to chase Lauren Price. The result completes a hard-fought rebuild after losses to Alycia Baumgardner and Natasha Jonas and consecutive wins over Sandy Ryan.
