This Saturday features two significant boxing rematches: Mikaela Mayer defending her WBO women`s welterweight title against Sandy Ryan in Las Vegas, and William Zepeda, the WBC interim lightweight champion, facing Tevin Farmer in Cancun, Mexico.

Mayer (20-2, 5 KOs) previously defeated Ryan (7-2-1, 3 KOs) by a majority decision at Madison Square Garden in September. Controversy preceded their first fight when Ryan was incident with paint thrown at her, which she blamed on Mayer`s team, allegations they denied.

Their rivalry intensified due to a trainer conflict. Kay Koroma, who trained Mayer for a long time, began training Ryan in September 2023. Mayer felt this was a conflict and switched to Kofi Jantuah after her defeat to Natasha Jonas in January 2024.

In their close first match, Mayer edged Ryan on the scorecards (93-97, 94-96, 95-95), with only one punch separating them in total connects (Mayer 186, Ryan 185) and power punches (Mayer 132, Ryan 128). Ryan, however, landed slightly more jabs (57 to 54).

Zepeda (32-0, 27 KOs) won against Farmer (33-7-1, 8 KOs) via split decision last November for the interim WBC lightweight title. The scoring was very tight, with judges differing by only one round (twice 94-95 for Zepeda, and 95-94 for Farmer).

Despite being knocked down in the fourth round, Zepeda threw significantly more punches (191 more than Farmer) but had a similar punch accuracy: 33.3% for Zepeda and 32.9% for Farmer. Zepeda also landed far more body punches (90 to Farmer`s 45).
