Women’s boxing takes centre stage again this Thursday as Mary Spencer defends her WBA light-middleweight title against Mikaela Mayer at the Casino de Montréal in Canada.
Spencer (10-2, 6 KO’s) enters as the defending WBA champion, yet she is the firm underdog in this one. The 40-year-old Canadian veteran brings size, experience, and genuine knockout power to the ring against Mayer.
Mayer (21-2, 5 KO’s), is the former unified champion at 130-pounds and a recent WBO welterweight titleholder. At 35, she’s moving up yet again in search of history as she’s attempting to become a three-division world champion.

Mary Spencer vs Mikaela Mayer: Analysis

Spencer is a natural light-middleweight who fights behind a stiff jab, marches forward, and looks to impose her physicality. She thrives when she can close distance and exchange, particularly in front of her home fans in Montreal.
Mayer, meanwhile, is a great technician. She’s a rangy, disciplined boxer with sharp fundamentals and an elite amateur pedigree. She excels at controlling tempo, managing range, and using angles to frustrate opponents. Her jab is among the best in women’s boxing, and her movement could neutralise Spencer’s power if she establishes rhythm early.
However, moving up in weight again presents new challenges. Mayer will likely be the smaller, lighter puncher in this division.
Spencer vs Mayer: Prediction & Betting Tips
This has all the makings of a tense, tactical battle. I expect Mayer to start fast, using her movement and jab to bank early rounds. Mayer’s ambition to become a three-division champion makes this a must-watch fight, and although Spencer is a big underdog, she does have the power to potentially hurt Mayer.
Mayer needs to rely heavily on activity and ring IQ, because standing in front of Spencer for prolonged exchanges could end badly. And I do think she will be methodical in this one.
My pick for this one is Mikaela Mayer to win by decision or technical decision at odds of 1.30 (Sky Bet). I do believe Mayer’s durability at the new weight will be tested, but I think she’ll be smart enough and quick enough to evade the heavy power shots and silence the home crowd that will be supporting Mary Spencer.
