Boxing superstar Claressa Shields -- the undisputed middleweight champ -- says she's 100% confident she could beat male fighters ... and she's calling them out by name.
Shields was a BEAST in her title fight this weekend against then-undefeated Christina Hammer -- dominating every round en route to an obvious unanimous decision. It's clear Shields is on another level.
The 24-year-old sensation is now focused on a superfight with the other reigning undisputed female boxing champ, Cecilia Braekhus ... and hopes to set up a PPV fight in the near future.
