Mark Magsayo is officially set for his stateside return.

The unbeaten featherweight contender headlines the latest edition of Premier Boxing Champions (PBC) on FS1, facing Rigoberto Hermosillo in the main event Saturday evening from Microsoft Theater in Los Angeles.

Both boxers made weight for the event as did all undercard participants. Manila’s Magsayo (20-0, 14KOs) weighed 127 pounds for his first fight in the United States since 2016. Locally-based Hermosillo (11-2-1, 8KOs) checked in at 126.6 pounds, as the Mexican southpaw aims to end a two-fight skid.

Their bout is scheduled for 10 rounds, as is the evening’s chief support which many have tabbed as the potential fight of the night.

Philadelphia’s Paul Kroll (7-0, 6KOs) makes his West Coast debut along with fighting a scheduled 10-round bout for the first time in his career, as he faces local prospect Lucas Santamaria (11-1-1, 7KOs) in a 10-round welterweight crossroads bout. Kroll checked in at 147 pounds, while Santamaria tipped the scale at 146.4 pounds.

Kroll is coming off of a 4th round knockout of Marcel Rivers in his Philly hometown this past January. Santamaria returns to the FS1 circuit less than two months after his 10-round split decision win over Mykal Fox this past August.

Also in action are 18-year old twin brothers Angel and Chavez Barrientes, both of whom make their U.S. debut in separate undercard bouts.

Angel Barrientes (2-0, 2KOs) weighed 120.8 pounds for a scheduled six-round clash versus Fernando Ibarra (2-3), who weighed 121.2 pounds.

Chavez Barrientes (2-0, 2KOs) came in at 123.6 pounds for his scheduled six-round affair with Ivan Varela (3-2), who was slightly heavier at 123.8 pounds.

The pair of first-year pros both celebrated their 18th birthday in August, making them eligible to fight anywhere in the United States. Both turned pro last November in Tijuana, where they returned this past March. The twins hail from Honolulu but currently live and train in Las Vegas.
