Brian Castaño doesn’t believe there is a junior middleweight alive today who can beat him.

Of course, he doesn’t mistake his unbeaten record as a sign of invincibility.

The former 154-pound titlist from Argentina is ready to re-enter the title mix following a 5th round injury stoppage of Nigeria’s Wale Omotoso in their FS1-televised headliner Saturday evening in Oxon Hill, Maryland. The win not only maintained his status as an undefeated boxer but also served as a reminder to the power players in the 154 pound division that he’s ready to take on all comers.

Whether or not his divisional peers are as willing is up for discussion.

“I’m pretty sure the other guys watched me; I’m not sure they want to fight me,” Castaño (16-0-1, 12KOs) told BoxingScene.com and other reporters following Saturday’s win, one that came with former unified 154-pound titlist Jarrett Hurd serving as part of the Fox Sports broadcast team. “They know I’m a dangerous fighter.”

The fight was his first since a 12-round draw versus Erislandy Lara this past March, with a planned rematch versus France’s Michel Soro falling apart over a dispute on financial assurances. The fallout led to the end of a title reign which dated back to an interim title win in Nov. 2016, though the decision made to vacate the belt and move forward with his career rather than grow stale on the sidelines.

The hope is to fight a reigning titlist next, whether Lara, Jaime Munguia (though he may be on his way to 160 very soon) or the division’s top dog in unified titlist Julian ‘J-Rock’ Williams. If not, any fight will do as long as it’s not another eight months between ring appearances.

“I need to stay busy. I am a fighter, this is my life. I need to fight and am willing to fight anyone.”

There are limits however.

“Fighting at] at 160 is too heavy. I’m too small.; I’m small for 154 already,” joked Castaño, who at 5’7” is already undersized against most divisional competition. “That said, show me [enough] money and the right opponent! There is Sergiy Derevyanchneko, who I fought in a platform that nobody recognizes as a pro fight (World Series of Boxing). He was a very strong guy.”

But I am a 154 pounder.”
