With Mexico versus Puerto Rico in the headliner, there's plenty of room for drama in the ring.

Miguel Berchelt and Jason Sosa kept it limited to fight night, as both easily made weight for their ESPN-televised junior lightweight title fight Saturday evening at Dignity Health Sports Park in Carson, California.

Mexico's Berchelt (36-1, 32KOS) weighed 129.8 pounds for the sixth defense of the 130-pound title he claimed in an 11th round stoppage of countryman Francisco Vargas in Jan. 2017. His most recent fight and defense came in a rematch with Vargas, enjoying a far easier go of things in a one-sided 6th round stoppage this past May in Tuscson, Arizona.

Sosa (23-3-4) weighed 128.2 pounds in his bid to become a two-time junior lightweight titlist. The 31-year old Boricua knockout artist from Camden, New Jersey hit paydirt in a come-from-behind knockout win over Javier Fortuna to win a 130-pound title, June 2016 in Beijing, China. Just one defense followed before having to vacate in order to accept a shot at a separate title, resulting in a one-sided April 2017 stoppage loss to Vasiliy Lomachenko. He enters Saturday's headliner riding a three fight win streak, including a 7th round knockout of Haskell Lydell Rhodes this past August.

In the chief support, Javier Molina weighed 141 pounds for a 10-round junior welterweight clash versus Japan's Hiroki Okada, who weighed 140.8 pounds

Also on the show, Alex Saucedo (28-1, 18KOs) returns for the first time since his failed title bid nearly one full year ago. The 25-year old from Oklahoma City, Oklahoma—who suffered his first defeat in a knockout loss to then-unbeaten titlist Maurice Hooker at home last November—weighed 139.6 pounds for a scheduled eight-round junior welterweight battle with Western Pennsylvania journeyman Rod Salka (24-5, 4KOs) who weighed 140.4 pounds.
