Amanda Serrano couldn't have fought any harder.

Over two nights in 2022 and '24, the Brooklyn-based Puerto Rican ventured from featherweight to the lightweight, and then the junior welterweight division to face rish superstar Katie Taylor in a pair of fights which produced the rarest of rarities.

They stopped the boxing world. Regardless of the outcomes, Serrano and Taylor had cemented themselves as icons of the much-maligned sport of women’s boxing, and they got paid handsomely in the process.

Friday at Madison Square Garden in New York City, they'll meet a third time, and Serrano is expected to fight as hard as she did in the first two bouts.

But this time, she expects to win. It's an outcome many believed she deserved the first time when the pair met in the same Garden ring, and even more thought she did enough to get the nod in their November rematch. But the only opinions that matter are always those rendered by the three judges ringside.

"Losing is never fun," Serrano said at Wednesday's final press conference from The Theatre of Madison Square Garden. "But you only lose if you feel like you lost, and I didn't feel like I lost. My team told me I didn't lose, they're proud of me, so I'm OK. Like Jake Paul says, turn that L into a W, and that's what we're gonna do come Friday night."

Serrano (47-3-1, 31 KOs) is a seven-division world champion. Her first loss came to Frida Wallberg took place in Serrano's 16th fight in 2012. So she was unbeaten for nearly a decade when the split verdict came down in Taylor’s favor 10 years later.

That stung, but the rematch was worse: Serrano nearly stopped Taylor early before seeing the champion roar back to last the distance. In the process, a clash of heads opened up a nasty cut over Serrano's right eye before Taylor lost a point in Round 8 for headbutts.

When the final round of an epic matching their first for high-level action and drama ended, the expectation was Serrano would even the score with her rival.

But she didn't, leaving a key question before the third fight: what more can Serrano do to get a win over Taylor if this fight looks like the other two?

"I'm always up for improvement," Serrano, 36, said, having moved her training camp from Brooklyn to Puerto Rico for this fight. "Obviously, the judges didn't see me winning the fight, so something has to change and I'm up for that.

"That's what we did in training camp. I'm going to use my head, but not the way it was used on me. We're going to work smarter, I work hard in every training camp, but we worked a lot smarter for this fight and I believe we can come out victorious."

Serrano quickly corrected herself.

"We will come out victorious."

As far as the cut — which required eight stiches — is concerned, Serrano isn't worried about a punch or another head clash opening it up. If that does reopen, so be it.

"If I had concerns, I would not take the fight," she said. "I'm a warrior, I'm gonna go in there and if that cut happens, we're prepared. You saw what I did. I fought to the very end in the last fight, and I'll do it over and over again if I have to. I'm a warrior."

That she is, with the resume to prove it. But all warriors wear down. And after 20 hellacious rounds together, many debate whether it's Taylor or Serrano on the verge of waking up Friday and not being the same fighter anymore. Then again, they said the same thing about Muhammad Ali and Joe Frazier before Manila, and we all know how that turned out.

So expect another war in a fight Serrano expects to win. But if she does, don't expect a fourth meeting,

"I'm kind of tired of Katie Taylor," Serrano laughed. "We had great moments together, great fights together but hey, two is better than one, right? So she'll have two and I'll have one, and she can live with that."
