Katie Taylor and Amanda Serrano have developed the greatest rivalry in the history of women's boxing with two fantastic fights. The women are set to face off one more time, headlining a card from New York's Madison Square Garden this Friday night with Taylor's four junior welterweight championships on the line.

A bit more than three years after they sold out Madison Square Garden—and just eight months after a rematch at AT&T Stadium—third-time rivals Amanda Serrano and Katie Taylor are sharing a ring once again in midtown Manhattan.

After Katie Taylor had defeated her for the third time to remain the undisputed 140-pound champion, Amanda Serrano was in tears.Not because of the sadness over her loss, but because of the appreciation for where women's boxing has gone since the two champions started their trilogy three years ago.
