Shields is one of only two boxers in the four-belt era to become undisputed in three weight classes -- Terence Crawford is the other. She unified all four major women's heavyweight titles on Feb. 2, 2025, with a win over Danielle Perkins and has since made two successful defenses.
Gabriela Fundora climbs one spot to No. 4 since our last update, and Mikaela Mayer remains at No. 6 after unifying three junior middleweight world titles. Also holding their positions following incredible victories are No. 7 Alycia Baumgardner and No. 9 Yokasta Valle. The biggest change comes from Elif Nur Turhan, who makes her top-10 debut after a standout performance against previously unbeaten Beatriz Ferreira.
Crawford (42-0, 31 KOs) defeated then-No. 8 Canelo Alvarez by unanimous decision in Las Vegas on Saturday, and the victory catapulted him from the No. 3 spot all the way to the top. It was a brilliant performance by Crawford, who moved up two weight classes to challenge Canelo for the undisputed super middleweight championship. The win also made Crawford the only men's fighter in the four-belt era (since 2007) to be undisputed champion in three divisions (junior welterweight, welterweight and super middleweight).
