Caroline Dubois warns Alycia Baumgardner against stopping short of undisputed

Caroline Dubois believes she is just one victory away from a showdown with Alycia Baumgardner in what would be one of the most appealing matchups in women's boxing.

On Sunday, in Arlington, Texas, Baumgardner stepped up to lightweight – where Dubois holds the WBC and WBO titles – to claim the IBF belt from Elif Nur Turhan.

Dubois, the unbeaten Londoner who is 14-0-1 (5 KOs), was ringside to watch Baumgardner cruise to a lopsided 10-round decision and wasted little time calling out the winner.

Baumgardner, who had ruled at junior lightweight, welcomed the challenge, but Dubois must first overcome WBA titlist Stephanie Han on February 20 before turning her attention to a potential clash for all four major belts.

And Dubois is adamant that Baumgardner, having made the move to 135lbs, should be prepared to go all the way.

"You have to challenge yourself, you have to test yourself and that test, the biggest test for her career is going to be against me. I knew she was going to have to step up," Dubois told Sky Sports of Baumgardner.

"What's the point of moving up in weight and having one belt? There's no point going halfway, you go all the way. When you're on a quest for greatness, you go all the way.

"I know for myself, I want to be undisputed. I'll be very frustrated if I fight and unify as much as I can and there's just one belt and she's terrified to step in the ring me and prevents me from becoming undisputed. I think that would be a whack move and I would be very disappointed.

"If she's as great as she says she is then hopefully that's the character she will have and she would relish the opportunity.”

Dubois also recognizes that a fight of such significance deserves an occasion to match, with both champions having plenty to gain – and lose – should they eventually share a ring.

"It's something that we both have to work towards, to make sure when the fight happens it's on the biggest platform, the biggest stage and we're given the respect we deserve for putting ourselves on the line."
