Mikaela Mayer crossed the border into Canada, and left with the WBC, WBA and WBO super welterweight titles as she claimed a comfortable points win against Mary Spencer at Montreal Casino on Thursday.
Mayer (22-2, 5 KOs) had already been world champion at super featherweight and welterweight coming into this one, while Spencer (10-3, 6 KOs) won the interim WBA belt with a points win against Naomi Mannes in September last year and was then upgraded to full champion, and was last out in April, taking a wide points win against Ogleidis Suarez.
Both started off on the jab in the opening round, but Mayer’s speed was the key, and a big left hand got Spencer’s attention.
The visitor’s jab worked well to the body in round two, and the pair then traded a round later, with Mayer again quicker on the jab, and another meaty left landed as she applied constant pressure.
Spencer did gamely put punches together in the fourth, but the 35-year-old was happy to exchange, and she was pushing back the naturally bigger Spencer as she connected.
The WBA champion was game, having her best round in the fifth with combinations and a sharp uppercut finding the mark.
Mayer, who beat Sandy Ryan for the second time in April, re-asserted, with her volume of punches and speed winning the day, but her progress was checked in the eighth as Spencer stunned the challenger with a right hand.

Again the Californian regrouped, and her relentless output saw her to the final bell, where the outcome was inevitable.
Mayer was crowned unified champion by scores of 100-90, and two tallies of 98-92.
Biyarslanov battles past Lipinets
NABF super lightweight champion, Arthur Biyarslanov was tested by former IBF world champion Sergey Lipinets before taking a points win in their ten round meeting.
Lipinets (18-5-1, 13 KOs) was on the deck in the third, but battled hard, and the contest eventually went the distance.
Biyarslanov (20-0, 16 KOs) got the nod by scores of 99-90, 97-92 and 96-93 to retain his belt.
Mathieu marches on
Big-punching super middleweight prospect, Wilkens Mathieu was another taken the distance, and he took the WBC Continental and NABF titles with a points success against Shakeel Phinn.
Phinn (27-4-2, 17 KOs) was down in the third but recovered to see the final bell, where two scores of 98-91 and a third at 99-90 saw Mathieu (15-0, 10 KOs) declared the winner.

Unal takes out Vilcans
In ten-rounders on the bill, WBC Continental Americas light heavyweight champion, Mehmet Unal retained emphatically against Latvia’s Ralfs Vilcans, taking an opening round stoppage win.
Vilcans (18-3, 7 KOs) had taken Anthony Yarde the distance last October, but was no match for Unal (14-0, 12 KOs) here.

Remaining Undercard
Christopher Guerrero (16-0, 9 KOs) defended his WBC Continental Americas welterweight title widely on the cards against Williams Andres Herrera (17-5, 7 KOs).
Scores of 99-91, 98-92 and 97-93 confirmed victory.
The sole eight-rounder saw Thomas Chabot (11-1, 8 KOs) defeated by Logan Clouthier at super featherweight, with Clouthier taking a points win (7-0, 4 KOs) and in the only four rounder, Erik Israyelyan (3-0, 2 KOs) had to settle for a split decision win against Dylan Schroeder (6-1, 4 KOs), also at super featherweight.
