The Night Katie Taylor and Delfine Persoon Forced the Boxing World to Pay Attention
On June 1, 2019, Madison Square Garden played host to Anthony Joshua vs Andy Ruiz Jr. On that same card, Katie Taylor faced Delfine Persoon. By the time the evening concluded, many observers were talking as much about the women who had fought as they were about the heavyweight upset that followed.
It was a fight that elevated women’s boxing, enhanced the reputations of both participants, and left behind a debate that still resurfaces whenever close decisions are discussed.
For Katie Taylor, it represented the most difficult test of her professional career to that point. For Delfine Persoon, it was the fight that finally introduced her to a wider audience. Both women left New York with their standing in the sport enhanced.
Taylor entered the contest with a perfect professional record of 13-0 and ownership of the WBA, IBF, and WBO lightweight titles. The 2012 Olympic gold medalist from Bray, Ireland, had been viewed as a transformational figure in women’s boxing long before she turned professional.
By 2019, however, Taylor still had something to prove. Although her professional accomplishments were impressive, critics questioned whether she had faced an opponent capable of pushing her to the limit.
Delfine Persoon was exactly that opponent. A former Belgian police officer, she did not begin boxing until her late teens and did not enjoy the extensive amateur pedigree that had propelled Taylor onto the international stage.
What Persoon possessed instead was relentlessness.
She entered the fight with a record of 43-1 and had held the WBC lightweight title since 2014. Her only professional defeat had come years earlier in a challenge for the WIBF super featherweight title. Since then, she had compiled one of the longest winning streaks in women’s boxing while largely operating outside the spotlight afforded to more marketable champions.
To casual fans, Persoon was not well known. To boxing insiders, she was.
The fight that night carried unusual significance. The winner would become the undisputed lightweight champion, holding the WBA, WBC, IBF, and WBO titles simultaneously.
The contrast in styles was evident from the opening bell. Taylor boxed with the technique that had made her one of the finest amateurs of her generation. Persoon fought with the urgency of someone who had something to prove.
The result was a fascinating clash. Persoon’s pressure was relentless. She threw punches in bunches, crowded Taylor at every opportunity, and forced the Irishwoman into exchanges that many had assumed she would avoid. Taylor responded with cleaner, sharper punching, often landing the more technically precise blows amid the chaos.
What emerged over ten rounds was a genuine contest.
There were moments when Persoon appeared to be overwhelming Taylor through sheer volume and determination. And there were moments when Taylor’s superior timing and accuracy seemed to be carrying the day. Neither fighter was able to establish prolonged control.
By the championship rounds, both women looked as though they had participated in a far longer contest. When the final bell sounded, there was little agreement about who had won.
That uncertainty only intensified when the scorecards were announced. Taylor received the verdict by majority decision. Judge Guido Cavalleri scored the bout even at 95-95, while judges Pawel Kardyni and Brian Coster returned scores of 96-94 (2x) for Taylor.
The decision immediately divided opinion. A number of media observers felt Persoon’s pressure and work rate deserved recognition. Others believed Taylor’s cleaner punching had carried enough rounds to justify the verdict.
Interestingly, the controversy itself became part of the fight’s legacy. The competitive nature of the bout increased public appetite for a rematch. That rematch eventually occurred in August 2020, again resulting in a narrow victory for Taylor.
Taylor emerged from Madison Square Garden that night with a record of 14-0 and the distinction of becoming the undisputed lightweight champion. More importantly, she had answered lingering questions about how she would respond when confronted by a world-class opponent capable of matching her determination and forcing her out of her comfort zone.
The victory became a cornerstone achievement in a career that would later include undisputed championships in multiple divisions and recognition as one of the most accomplished female fighters of her era.
Persoon left New York with a record of 43-2. It may have been the most valuable defeat of her career. Persoon became recognized internationally as one of the sport’s elite competitors. Boxing enthusiasts were impressed by her toughness, stamina, and refusal to yield against one of the biggest names in the sport.
