Savannah looks a little more serious than I expected. She has a look befitting a fight of this size and an event of this magnitude.

Alycia Baumgardner: "It was easier than I expected but she ran into my gameplan.
"I kept clocking her every time she was coming in. She knew what the right hand was going to do and I kept the jab pumping.
"I'm the unified champion of the world. I won, that's all that matters.
"She isn't getting a rematch, I'm going after Choi [Hyun-mi] for the undisputed."

And it continued into their latest new conference, in which Claressa Shields promised to "school" Savannah Marshall.
Neither woman backed down during verbal exchanges, with Shields telling Marshall: "You about to get schooled.
"I'm about to Sugar Ray Leonard her."
Shields and Marshall, both undefeated in 12 fights, have known each other for the best part of a decade having met at the 2012 World Championships.
Savannah's win over Shields on that occasion remains the only defeat the WBA, IBF and WBC champion has suffered as a fighter.
"She's a bum," Shields insisted. "I'm about to show everybody that there's levels. She thinks I'm still 17, I'm 27. You about to learn."

Just look at how the original news conference went last month, before the fight was postponed following the death of Queen Elizabeth II.

I don't think you can complain.
I'm not sure either of them truly believe they've won that fight clearly.

Alycia Baumgardner in her post-fight interview: "I told the haters... yeah, I did that!
"I did think I did enough. I landed the cleaner shots, the harder shots. I cut her on her forehead. I dug deep."
She finished by saying there "ain't no rematch". She wants to face Choi Hyun-mi for the undisputed super featherweight crown.

There's a nice gesture at the start of the final round as Mikaela Mayer and Alycia Baumgardner touch gloves.
Baumgardner landed some more big shots but it just feels like Mayer has had more control and consistency throughout.
Has she done enough to stretch her unbeaten record and become the unified super featherweight champion?

Both the American champions landed some stinging blows there. It's getting close to call this one.
