Kaitlin O'Toole: Amanda Nunes defeated Felicia Spencer in the UFC 250 featherweight main event on Saturday. She is now the first fighter in UFC history to win and defend championship belts in two separate weight classes simultaneously. Joining me now for a recap on the fight is SI's Justin Barrasso. Justin, Nunes had to go all five rounds to get the victory, but she was dominant in doing so.

Justin Barrasso: Yeah, Nunes did everything but finish the fight. I mean, it was a glorified sparring session. It was the best fighter in the world and someone doing everything she could, and Felicia Spencer trying to survive, trying not to drown. And that's not easy against Amanda Nunes, and she got in very little offense. Even after the fight, Nunes said in a press conference as soon as she got hit the first time by Spencer, she knew that just those punches weren't going to knock her out. They weren't gonna do damage. And that's not like post-flight trash talk. She was telling the truth for five rounds. There was no mark on her, and you look at Spencer and she was battered and bloodied. It was a very, very one sided fight.

Kaitlin O'Toole: Absolutely, Nunes dominated. So I want to talk about what's next for her, she really doesn't have any legitimate contenders to move on to. So what do you see Nunes doing?

Justin Barrasso: You're right. In two divisions too. So it's not like she doesn't have featherweight contenders, but she doesn't have featherweight contenders, she doesn't have bantamweight contenders. She's mauled her way through two separate divisions, which is incredible. Next on her plate is motherhood. She and her partner are expecting this fall. So that'll be something exciting for her, something new. But in terms of the fight game, probably Valentina, you have a trilogy fight there. But normally in a trilogy fight, like with, for instance, Daniel Cormier and Stipe Miocic, the fighters split the first two. Nunes won both those first two fights. So I don't know. I mean, that would be a competitive fight. I think Valentine is world class. Amanda clearly is the best in the world. And there comes a point where no one remains untouchable forever. But it was funny after the fight on Saturday, Nunes just out of sportsmanship, put her belt on Felicia Spencer's shoulder. And that's probably the closest anyone will get to either of her titles anytime soon. So I don't know. We'll see. I mean, she's definitely going to keep fighting. But in terms of a legitimate threat right now, probably Valentina. There just aren't many others.
