UFC strawweight champion Joanna Jedrzejczyk is urging the promotion to formally open a new, 125-pound women’s division so she can add another belt to her collection.

“I want to be the first champion of the 125-pound division,” she told MMAjunkie on a media call in support of her third title defense at The Ultimate Fighter 23 Finale. “I think the UFC should do this move.”

Jedrzejczyk first rematches rival Claudia Gadelha, who coached opposite her on “TUF 23” and bickered on set. After Jedrzejczyk won a split call two years ago at UFC on FOX 13, the two headline the FOX Sports 1-televised show finale on July 8 at Las Vegas’ MGM Grand Garden Arena.

While Jedrzejczyk (11-0 MMA, 4-0 UFC) and Gadelha (13-1 MMA, 2-1 UFC) might not agree on much, they both think the idea of a 125-pound division is a good idea.

“A lot of good fighters at bantamweight can do very well at flyweight,” Gadelha said.

So far, the UFC has promoted only one women’s flyweight bout, a meeting between Joanne Calderwood and onetime strawweight title challenger Valerie Letourneau, who welcomed the extra poundage after suffering mightily to make 115 pounds.

Champ Jedrzejczyk cited that fight, which took place earlier this month at UFC Fight Night 89, as one example of the potential of a new women’s division, even though a series of wardrobe malfunctions lent it some odd moments.

“I used to compete at 125 (pounds), and I feel a big difference,” she said. “I’m not having a big problem with the weight cut, but ‘Jojo’ and Valerie, they had some problems at strawweight, but the fight at 125 looked amazing. It’s good for all of us.”

But most of all, it could be good for Jedrzejczyk, whose plans for 2017 ideally include the inaugural flyweight title.

Asked who would be the other No. 1 contender in the division, the champ couldn’t say. She just wants to be first.

“I think it’s going to be the last fight between me and Claudia, because I have plans to move to 125, if there will be an option to fight for a title next year,” she said.
