American Mayer becomes three-weight world champion

In Canada, Mikaela Mayer defeated Mary Spencer to become a three-division world champion and unified light-middleweight champion.

The 35-year-old American outlasted the hometown favorite over 10 rounds at Montreal Casino.

As Mayer claimed the WBC and WBO belts after retiring trailblazer Cecilia Braekhus, judges scored the contest 100-90, 98-92, and 98-92.

This is extra special because I’ve previously won a WBO, but I’ve never had the WBA or WBC put around my waist, Mayer said.

The Californian varied her body and head attacks before finding her rhythm behind a sharp jab.

She maintained control of the range and tempo throughout despite being only two inches taller than the 5’11” Spencer.

Mayer reawakened after a pair of right-handers connected in the fourth round to close the eighth round with four potent hooks, which appeared to be inevitable.

At the conclusion of the 13th bout, Spencer suffered a third defeat and was left with a mark under both eyes.

In a contested fight, she had hoped to face Wales’ WBC welterweight champion Lauren Price.

Promotional and broadcast issues largely caused the fight to fail.

If Mayer’s next fight with Price, who is scheduled to return to the UK in December, does not materialize, she may fight IBF champion Oshae Jones, who is unbeaten.

Mayer said, “The most crucial thing is that I have choices.”

“I’d love to do both: go back to 147 pounds for undisputed and then come back to 154 pounds to defend.”

Claressa Shields, the self-declared “Greatest Woman of All Time” and undisputed three-weight world champion who currently holds titles at heavyweight, could also face off in a potential super-fight.

Several promoters are interested in American Shields, who is currently a free agent, including co-founded by Jake Paul and Nakisa Bidarian Most Valuable Promotions.
