Robinson Castellanos will try to score his third straight upset when he meets Oscar Escandon on March 5 at the DC Armory in Washington, DC, Golden Boy Promotions announced on Monday.

The bout will be part of the non-televised undercard supporting Luis Ortiz vs. Tony Thompson at heavyweight. Castellanos-Escandon will be part of the international broadcast and streamed live on RingTVLive, which is available on RingTVLive.com, YipTV.com and the Ring TV channel via Amazon Fire, Roku and Filmon.com. (The Ring TV live stream starts at 9 p.m. ET.)

After losing seven of his first 10 professional fights, Castellanos (23-11, 13 knockouts) maneuvered into his current position with a pair of upsets, topping Rocky Juarez in Jan. of 2015, in an exciting brawl, and stopping previously undefeated Ronny Rios in the fifth round in Oct. of 2014.

Castellanos, the WBC mandatory challenger, cited his home city of Guanajuato, Mexico, which he said has not produced a world champion in nearly four decades, as motivation.

“This is the biggest fight of my career,” Castellanos said in a press release. “I know that Oscar Escandon is going to be a tough opponent. He is a former Olympian with recent victories over other difficult fighters like Jesus Cuellar. But I feel very strong, focused. The state of Guanajuato has not had a world champion in more than 35 years and to be able to fight for a world title as a representative of my home is a big motivator for me.”

Escandon (24-2, 16 KOs), who is promoted by Sampson Boxing, was initially penciled in to face titleholder Gary Russell Jr. on Nov. 14 but the fight was scuttled after Russell was cut in sparring. Escandon referenced his newborn daughter as inspiration for this fight. He dropped a split decision last April to Moises Flores in his most recent fight.

“I want to dedicate this fight to my newborn daughter,” he said in the release. “I feel very happy and thankful to be fighting for the world title. I know Robinson; he is strong, hard puncher but I am going to be 100 percent prepared for this fight. I have been training very hard and want to make sure I take the title back to my home. May the best man win.”
