Ramirez (26-0, 17 KOs) has been a world champion since March 2018, when he toppled Amir Imam via unanimous decision to win the vacant WBC strap. Following the Imam victory, he hired noted trainer Robert Garcia, and the duo has combined to go 4-0 in world title fights. Ramirez knocked out Maurice Hooker in July 2019 to unify world titles and defended his belts last August with a majority decision over former world champion Viktor Postol. Taylor toppled Postol by unanimous decision in 2018 and won the IBF world title the following year with a decision over Ivan Baranchyk. He unified the IBF and WBA titles in October 2019, edging Regis Prograis by majority decision in a brutal masterpiece. He made his first defense as a unified champion last September, blasting out mandatory challenger Apinun Khongsong in the first round.

2016 U.S. Olympic silver medalist Stevenson (15-0, 8 KOs) will headline in Las Vegas for the third time as he seeks to capture a world title in a second weight class. One of the world’s top pound-for-pound talents, Stevenson is tasked with turning back Nakathila (21-1, 17 KOs), who has won 10 consecutive fights by knockout since the lone defeat of his career.

Japanese star Inoue (20-0, 17 KOs) has already cemented his legacy as one of his nation’s great fighters, winning world titles in three weight classes and sporting a record of 15-0 with 13 knockouts in championship fights. He made his Las Vegas debut last October and knocked out Australian contender Jason Moloney with a straight right hand that became an instant viral highlight. Dasmarinas (30-2-1, 20 KOs) is 12-0-1 since the last defeat of his career, a run that includes a 2018 knockout over three-time European bantamweight champion Karim Guerfi.

“Loma” is back. The Ukrainian superstar and future Hall of Famer fights for the first time since last October’s showdown against Teofimo Lopez for the undisputed lightweight world title. Lomachenko’s return comes against Nakatani (19-1, 13 KOs), a longtime Japanese contender who most recently knocked out Felix Verdejo in one of the best fights of 2020. Lomachenko (14-2, 10 KOs) won a pair of Olympic gold medals before turning professional in 2013, and he then proceeded to win world titles in three weight classes in his first 12 fights. The “pound-for-pound Picasso” will be giving up roughly five inches in height and six inches in reach to the naturally bigger Nakatani.
