Mary Spencer vs Mikaela Mayer Is Set For October 30th In Montreal; Plus Mathieu vs Phinn

Press Release:

There will be two main events at the Casino de Montréal on October 30. WBA super-welterweight world champion Mary Spencer will face American two-division world champion and pound-for-pound great Mikaela Mayer in one of the most significant women’s boxing matches ever held in Canada. Then, in a high-stakes local clash with two titles on the line, young sensation Wilkens Mathieu will take on Quebec warrior Shakeel Phinn in a highly anticipated super-middleweight clash.

A Canadian Olympian at the London Games and a three-time amateur world champion, Montreal-based Mary Spencer (10-2, 6 KOs) has developed into a top-level pro. Last September, she won the WBA super-welterweight world title against Germany’s Naomi Mannes. This past April, she successfully defended it by dominating former two-time world champion Ogleidis Suarez over 10 rounds, despite a serious hand injury. Now fully recovered, Spencer is more determined than ever to win her third straight world title fight.

Across the ring, Mikaela Mayer (21-2, 5 KOs), will be in the unusual position of challenger. An Olympian at the Rio Games, the Top Rank-promoted native of Los Angeles has held the WBO, IBF, and The Ring super featherweight titles. She later moved up to lightweight, capturing the interim WBC title, and in September 2024, won the WBO welterweight world title at The Theater at Madison Square Garden with a hard-fought majority decision over Sandy Ryan. She defended that belt in March, topping Ryan by unanimous decision in their rematch.

While the Spencer vs. Mayer bout features two established champions, the Wilkens Mathieu (14-0, 10 KOs) vs. Shakeel Phinn (27-3-2, 17 KOs) clash will feature two fighters with something to prove.

Being the underdog has never intimidated Shakeel Phinn. In May 2024, “The Jamaican Juggernaut” stepped into the ring at the Casino de Montréal against another undefeated EOTTM fighter, Erik Bazinyan. Despite being a heavy 8-to-1 underdog, Phinn shocked everyone by fighting to a draw — a result he believes should have gone in his favor. Determined not to leave anything to the judges this time, Phinn returns to the Casino with a clear mission.

Also on the October 30 card, three other champions will be in action. Top-10 super-lightweight contender Arthur Biyarslanov (19-0, 16 KOs) will make his fourth NABF title defense. Top-15 light heavyweight contender Mehmet Unal (13-0, 11 KOs) will defend his WBC Continental title for the first time, and top-20 welterweight contender Christopher Guerrero (15-0, 9 KOs) will make his second defense of the WBC Continental title. Fan favorite Thomas Chabot (11-0, 8 KOs) will also return to action, while rising junior amateur world champion Erik Israyelyan (2-0, 2 KOs) will look to keep his flawless record intact
