The changes Mary Spencer made to her team and her training methods weren’t enough to help her win her rematch with Femke Hermans on Wednesday night in Montreal.

The decorated Canadian amateur was sharper than she was when Spencer lost their first fight on points, but Hermans had plenty of success during the second half of their 10-round rematch and won a majority decision at Montreal Casino. Belgium’s Hermans won on the cards of judges Sylvain Leblanc (96-94) and John Rupert (97-93), though judge Martha Tremblay scored their second fight a draw, 95-95.

Hermans retained her IBO super welterweight title and claimed the previously vacant IBF junior middleweight title in a main event ESPN+ streamed.
