Katie Taylor has been listed no.2 in Ring Magazine's inaugural women's pound-for-pound rankings.
It's the first time in the 98-year history of the famous magazine that female boxers have been ranked in a similar manner to their male counterparts.
Topping the list is three-weight world champion, Claressa Shields.
A 2012 and 2016 Olympic gold medalist, the American is unbeaten in her 10 professional bouts to date, with two of those wins by knock-out.
Despite being ranked ahead of Taylor, Shields appears unhappy with the view of the top-10 from one of its panelists, Diego Morilla.
He said, "I honestly believe that if Claressa Shields had been fighting out of either one of those two corners [in Persoon v Taylor], we would have seen her ‘0’ disappear."
"Some lady said she believe that If I had to fight from either corner in a tough fight that I’d lose? Lol," Shields tweeted, "She just missing the point that I’m that great to where I don’t have to.
"I’ve had adversity happen to me in the ring. I’ve been knocked down “unlike” Taylor.
"But I got up off my butt to win the fight UNANIMOUSLY!
"And Taylor does not have better defense [sic] than me. I won’t be losing or having a split decision fight no matter who I face."
Taylor defended her lightweight titles on Saturday night by beating Delfine Persoon by unanimous decision.
It followed a contentious bout from June 2019, when Taylor need a majority judges' decision to take Persoon's WBC belt.
Shields' Twitter outburst will again raise talk of a meeting with Taylor, but it's something the American has previously dismissed.
"We are just too far apart," Shields told Sky Sports in June, "That’s a great fantasy fight, but the lowest I can go is 154lbs, that’s a big push. 147lbs is a bigger push, and I don’t even think Katie can get to 147lbs.
"She has always been small, she isn’t that tall, I don’t even know her to have ever been over 155lbs…. so?
"I can’t make 140lbs, I think I can make 147lbs, but you never know till I am motivated and pushed to have to go down there."
Persoon is ranked only behind Taylor in the lightweight division, and 6th overall.
Despite suffering a shock defeat to Jessica McCaskill earlier this month, Cecilia Braekhus is ranked no.3 overall with McCaskill no.4.
Rounding out the top-5 is Katie Taylor's original opponent for this past spring, Amanda Serrano.
