MONTREAL, Canada (Oct. 28, 2025) — Two-weight queen Mikaela Mayer looks to conquer a third weight class on enemy soil.
Mayer will challenge Canadian fan favorite Mary Spencer for the WBA super welterweight world title this Thursday, Oct. 30, at Montreal Casino in Montreal, Canada. The vacant WBC and WBO belts will also be up for grabs in this newly minted three-title showdown.
Mayer (21-2, 5 KOs) is the current WBO champ at welterweight, defeating Sandy Ryan via majority decision in September 2024 before securing a more decisive triumph in March's rematch. Spencer (10-2, 6 KOs), a 2012 Olympian, defended her title in April with a unanimous decision over former world champion Ogleidis Suarez.
Promoted by Eye of the Tiger and Top Rank, Spencer-Mayer and select undercard bouts will stream on Top Rank Classics in the U.S. beginning at 8 p.m. ET/5 p.m. PT. Top Rank Classics is free and available on major FAST hubs.

At Tuesday's press conference, this is what the main event fighters said:
Mary Spencer
“I saw the odds. I know that I'm the underdog according to the bookies, but I mean, they get it wrong often. I don't feel like an underdog. I feel like this fight is a gift.”
“I know where I'm at as far as training, where I'm at in my life, and I felt even before this fight was matched that the next opponent was going to be in trouble, whoever that was. And now the situation is even more exciting because it's Mikaela, because of the style that she brings.”
“I get to be here at home. I get to really show a hometown crowd my best, and I'm very excited for that.”
“I think the key to victory is going to be me staying comfortable and being myself in the ring, and just being calm.”
Mikaela Mayer
“I’m really happy to be back here in Canada. I haven't fought in Canada since my amateur days, back when I first learned of Mary Spencer. It's great to be back."
"I have a big job to do on Thursday night. It's always been my goal in this sport to go and search out the best fights possible, the biggest names possible."
“I’ve had a great career so far. I did my thing at 130. I moved up to 147 and became a champion there, but my goal is to go undisputed. I couldn't get that undisputed fight against Lauren Price at 147, so my goal is to find the next best challenge for me. And when Mary Spencer's name came up, I said, yep, let's go to 154. Let's take that challenge.”
“She's a worthy opponent. She's done a lot in the sport. You know, I remember her name from back in the day. She was the it girl back in the amateurs, so those are the type of names I want to add to my resume, and we got the fight done, so I'm happy to be here.”
“I plan on getting my hand raised Thursday night, becoming a three-division world champion, and then me and my team will decide what we'll do from there."
"There are lots of big fights ahead of me, but the number one goal right now is to put on a great performance, show everyone that even though I'm the smaller fighter, skills pay the bills. Size doesn't win fights, skill does."
"So, that's what I'm going to do Thursday night. I'm going to trust my corner and trust the game plan that we have. It was a really long camp. We put in a lot of work in, so I'll be ready to put on a great show for you guys.”
