Katie Taylor enjoyed her finest hour at a point when most didn’t expect it.

More history was created by the Irish icon, who edged England’s Chantelle Cameron to avenge her lone career defeat. A ten-round, majority decision win saw Taylor join Claressa Shields and Terence Crawford as the sport’s only two-division undisputed champions in the four-belt era as she claimed the junior welterweight crown.

Best of all, the 37-year-old boxer returned to the site of her loss to Cameron six months prior, to accomplish the feat.

“It definitely feels like the greatest performance of my career,” Taylor told a group of reporters during the post-fight press conference Saturday evening at 3Arena in Dublin. “This was the longest six months of waiting for this rematch. These past few weeks, I just went to bed thinking about this rematch. Just the pressure as well. It came to be that people were writing me off. This win meant so much to me.

“It’s great to prove people wrong. I’m back on top again.”

Taylor (23-1, 6KOs) was adamant about an immediate rematch with Cameron (18-1, 8KOs), who earned a ten-round, majority decision in their May 20 undisputed junior welterweight championship at this very venue.

Cameron entered both fights as the defending champion but was made to feel like the B-side during their first meeting, which marked the long overdue Ireland homecoming for Bray’s Taylor. The party was spoiled when Cameron jumped out to a big lead and fended off a late Taylor rally to earn the win and defend her crown.

Taylor entered Saturday’s rematch with renewed purpose. She jumped out to a stronger start and avoided a knockdown call late in round one to build a sizable lead. She was ahead on all three scorecards through three, four and five rounds and had the fight locked up on two cards even before the tenth and final round.

Judges Steve Morrow (96-94) and Jan Christensen (98-92) had Taylor ahead, which overruled the scorecard of Ferenc Budai (95-95) to complete the changing of the guard at junior welterweight.

“Everyone watching the [first] fight knew it wasn’t myself last time,” Taylor said of the difference in her performances between the two fights. “I definitely felt a lot better this fight. I knew it was going to be a lot different. I knew when I stepped into the ring I would be myself and was going to win the fight.”
