Mikaela Mayer beat Mary Spencer by marching straight into her backyard, booting the door off the hinges, and helping herself to every belt on display.
The Montreal crowd came to roar for their hometown favourite, but by the third round, you could hear a pin drop. Mayer wasn’t there for selfies or sightseeing. She came to put in a shift, and by the final bell, Spencer looked like she’d been through a storm.
Ten rounds of sharp, spiteful boxing — jab, hook, pressure, repeat — and it wasn’t remotely close. The cards said it all: 100-90, 98-92, 98-92. A schooling.
Mayer left Canada with the WBA, WBC, and WBO super-welterweight titles strapped around her shoulders, adding them to her WBO welterweight crown.
Four belts. Two divisions. One fighter who refuses to be anyone’s stepping stone.
The smaller woman fought like the bigger boss
On paper, Spencer was supposed to be the stronger one — the local hero, the bigger frame, the puncher. But paper lies.
As soon as the bell rang, Mayer started bullying her. Walked her down behind a stiff jab, slipped inside, and smashed those right hands into the body like she was collecting rent.
Spencer tried to circle out, but Mayer cut the ring off like a pro and didn’t give her a sniff of breathing space. By halfway through, Spencer’s game plan looked about as sturdy as wet cardboard.
“Usually, I’m the taller fighter,” Mayer said after, still grinning through a bit of blood and sweat. “But because I’m usually the taller fighter, I also know how to beat me. I knew I had to come up underneath Mary Spencer and come over the top with big hooks. That’s what we trained for.”
And fair play — she pulled it off. The last few rounds were one-way traffic. Mayer was walking her down like she owned the place, snapping her head back, landing clean hooks at will. Spencer looked like she wanted to be anywhere else.
Mayer’s rebuild has been brutal — and she’s finally back on top
You can tell this one meant a lot. The last couple of years haven’t been kind to Mayer. Bad breaks, tough losses, dodgy matchmaking — she’s had to graft her way back up. But now she’s right where she belongs, with gold on her shoulders and a point to prove.
“I think the most important thing is I have options,” she said. “You always want options. I came off two years where my career kind of took a left turn. I had to navigate my way back to this position. Having options is a blessing.”
And she’s got them. Mayer can drop back to 147, chase undisputed, or stay put and defend at 154. Either way, she’s the one holding the cards now.
“I can go back to 147, become undisputed there, and maybe come back up and defend at 154,” she added. “We’ll go over it with the team.”
You can tell she means it. No PR fluff. Just a fighter talking like someone who’s been down, dusted off, and figured out who she is again.
Ringside view
From ringside, it was clear who was running the show. Mayer didn’t rush. Didn’t get drawn into anything stupid. Just boxed — mean, tidy, patient.
Spencer had her moments early, but once Mayer found her rhythm, she just turned the screw. Every round, a little more pressure, a few more clean shots, until the noise in the arena died off completely.
It wasn’t flashy. It was proper, hard, professional work — the kind that doesn’t make viral clips but wins big fights. You could see Mayer’s composure from bell one. No nerves. No panic. Just control.
By the end, Spencer was still standing, but that’s about all she could claim. Mayer didn’t celebrate big, didn’t show off. She just smiled — that quiet “told you so” grin — the kind fighters wear when they’ve just shut everyone up.
Three new belts, one more layer to her legacy.
Mayer’s back, and she’s still got more to take.
