That was astonishing from Natasha Jonas. I had reservations about the big weight jump, but Jonas' power translated in super fashion.
A right hook put Christian Numas down in the first and then a mirror left finished the job in the second. Punch perfect performance from Jonas.
At the third time of asking, and at the age of 37, Natasha Jonas is the champion of world.
Christian Namus didn't want it stopped, but Jonas does not care she's absolutely delighted and is the new WBO world super-welterweight champion via second-round stoppage.
Christian Namus, for the second round in a row, is knocked down. She again gets to her feet and wants to carry on, but referee Howard Foster looks into her eyes and says no and waves it off...
Round 1 - Jonas v Namus
What a start from Natasha Jonas, she slips a jab, hits Namus with a rapid-fire straight left and that sets up a beautiful, crushing right hook that floors Namus.
Here we go. Is this the moment for 37-year-old Natasha Jonas?
Vacant women's WBO World Super-Welterweight Championship
This is how the fighters match up, and this one is over 10x2 minute rounds.
Natasha Jonas v Christian Namus
Natasha Jonas had to deal with a late change of opponent last week when Ewa Piatkowska contracted Covid-19, but Jonas is not complaining, having seen other opportunities to compete for a world title greatly reduced.
"Katie Taylor is in a two-fight deal with Amanda Serrano, [WBC light-welterweight champion] Chantelle Cameron is in a tournament. I'm not sure what [undisputed welterweight champion] Jessica McCaskill is doing and Terri Harper got beat," she said.
"So, it left a very slim choice and then Ben came to me and said, 'Look, I can get you [a world title fight at] 154lbs', and why would I say no?
"I've said I can't complain and be fussy about who it is - so why would I complain if it's just a little bit heavier?"
We mentioned some footballers in the arena, Manchester United striker Edinson Cavani is also there, cheering on his fellow Uruguayan Chris Namus.

Natasha Jonas v Christian Namus
Natasha Jonas will be hoping it will be third time lucky in her quest to become a world champion.
Jonas, who was a stand-out amateur, fell agonisingly short of becoming a champion in her world title fights against Terri Harper at super-featherweight and Katie Taylor at lightweight.
The 37-year-old now has a third opportunity to accomplish her dream against Christian Namus, with the vacant WBO light-middleweight title up for grabs.
"When I first signed to Boxxer, I spoke with [promoter] Ben [Shalom] and said, 'I want to be a world champion - can you do it?' and he promised me that he could," Jonas told BBC Radio 5 Live.
Jonas is jumping up three weight divisions but weighed in two pounds heavier than her opponent at 10st 9lbs 5oz.
Music superstar Noel Gallagher and footballers Jamie Carragher, Jack Grealish and Micah Richards are among the early celeb spots at the AO Arena.
There will be more.

Wayne Ellis: Think Brook would have won well inside the distance when both were in their prime, but think he’s been in too many wars since then.
Robert: Brook by KO. Khan’s whiskers ain’t getting stronger.

BBC Sport at Manchester Arena
Is this really happening? Pinch me and wake me up.
The 'better late than never' narrative is irrelevant (and perhaps a little boring) now. Khan v Brook is here. I'm buzzing. The Manchester Arena is buzzing. The boxing world, whether they admit it or not, are buzzing.
The general feeling ringside is this is a true 50-50 fight. One former world-title challenger (who would like to remain anonymous) told me today that he expects Brook to stop Khan within three rounds. Earlier in the week, Anthony Crolla said he's edging towards Khan.
Who will secure bragging rights? Will one or both retire? Will they embrace post-fight? We don't have to wait long to for answers!
At 9pm we asked you who was going to win the main event - with thumbs up for Amir Khan and thumbs down for Kell Brook.
It's a good split, but the majority of you are backing a Brook win.
Frazer Clarke, speaking to Sky Sports, says: “I’m under no illusions that that opponent, no disrespect, was a bit of a soft touch. I’m in boxing to box.”
“My job was getting here and doing what I do best.”
“I tried to slow it down a bit, not to rush. I had the perfect opponent to do that. I understand there’s a long way to go. I’m not quite where I want to be physical. It’s just the start of the journey. I’ve got loads to learn.”
“I’ve been thinking about that [ring walk] for 12 years. A lot of thought went into that.”
It took two minutes and Frazer Clarke is an easy, easy winner. Jake Darnell is brave, but out of his depth taking some brutal punishment early on.
His corner saves him from any further punishment and after two minutes and six seconds the towel comes in.
