Claressa Shields can make her case as the most decorated U.S. amateur boxer in history after repeating as World champion on Friday.
Shields beat the Netherlands’ Nouchka Fontijn via unanimous decision in the middleweight final in Astana, Kazakhstan.
Shields, who won gold at age 17 in women’s boxing’s debut at the London Olympics and took her first World title in 2014, became the first American to capture three combined global titles.
“I have never had these emotions before, and it was definitely overwhelming,” Shields said, according to USA Boxing. “This World Championships was different because I was coming in as the reigning World champion, not just the Olympic gold medalist. I had a standard to uphold, and that was to dominate everyone.”
Many great U.S. Olympic champion boxers, such as Muhammad Ali and Joe Frazier, fought before the World Championships debuted in 1974 (and Worlds switched from every four years to every other year starting in 1991).
Shields, of Flint, Mich., moved to 74-1 overall and has won 48 straight fights since her only loss to Great Britain’s Savannah Marshall at the May 2012 World Championships, according to USA Boxing.
Shields and Marshall were in line to face each other at the 2012 Olympics, 2014 Worlds and 2016 Worlds, but each time Marshall was eliminated one round before their potential rematch.
Shields will not fight again until the Rio Games in August, where she can become the first American boxer to earn gold at multiple Olympics.

Corrections: An earlier version of this post had the wrong name of a British boxer. Her name is Savannah Marshall, not Sarah Marshall. Shields’ record was also updated from 73-1 via USA Boxing to 74-1 via USA Boxing.
