Mikaela Mayer and William Zepeda Set to Defend Titles in High-Stakes Rematches

Mayer faces Sandy Ryan in Las Vegas, while Zepeda takes on Tevin Farmer in Cancun, with career-defining implications for all fighters.

Mikaela Mayer will defend her WBO welterweight title against Sandy Ryan on March 29, 2025, in Las Vegas, following their razor-thin first fight in September 2024.
William Zepeda, heavily favored at -770 odds, will defend his WBC interim lightweight title against Tevin Farmer in Cancun, Mexico, after a contentious split-decision win in their first bout.
The Mayer-Ryan rematch is fueled by a personal rivalry that includes past accusations of assault and disputes over trainer affiliations.
Zepeda’s performance is under scrutiny after criticism of his first fight with Farmer, and a victory could position him for a potential showdown with Shakur Stevenson.
Both rematches carry significant stakes, with title defenses, divisional rankings, and future opportunities, including potential unification bouts, on the line.
