Jermell Charlo has already proven a penchant for getting it right the second time around.

The lone loss in Charlo’s career was emphatically avenged, scoring an eleventh-round knockout of Tony Harrison in December 2019 to regain the WBC junior middleweight title he lost to the Detroit native exactly 52 weeks prior. Charlo has since added the lineal championship and WBA/IBF belts to his collection, all of which he retained in a 12-round draw with WBO titlist Brian Castano last July in San Antonio, Texas.

The two are set to do it again on May 14 at Dignity Health Sports Park in Carson, California—less than an hour from the Toyota Arena in Ontario where he defeated Harrison to begin his second title reign.

“You don’t give people like me opportunities again,” Charlo told BoxingScene.com and other reporters during a recent Zoom media conference call to discuss the undisputed championship rematch. “If you get an opportunity like this, you got to seize this opportunity. I’m super sharp, laser focused. I’ve been grinding.

“While [Castano was] complaining about [his] bicep, I’ve been grinding. You gave me more time to prepare my mind and body. While you over there playing games, I'm gonna have your ass in there crying.”

Houston’s Charlo (34-1-1, 18KOs) and Argentina’s Castano (17-0-2, 12KOs) will be ten months out from their first fight by the time the opening bell sounds for their Showtime main event. The two fought to a split decision draw last July 17 at AT&T Center in San Antonio. Charlo won on the card of Nelson Vasquez (117-111), whose wide score became the subject of public scorn. Judge Steve Weisfeld (114-113) saw Castano barely edging it, while Tim Cheatham (114-114) scored six rounds apiece to the pair of junior middleweight titlists.

Charlo entered riding a three-fight win streak following his disputed loss to Harrison to end his first title reign in December 2018. A contentious buildup preceded their rematch, which was delayed by six months after Harrison suffered an ankle injury during training.

Similarly, Charlo was made to wait another two months for his second fight with Castano, who suffered a slight biceps tear which postponed their previously scheduled March 19 clash to have taken place at Crypto.com Arena in Los Angeles. The delay only gave Charlo that much more time to think about how he plans to remove any doubt as to who is the true king of the junior middleweight division.

“One thing Brian Castano knows is, he got his hands full again,” vows Charlo, whose twin brother Jermall defends his WBC middleweight title next month in Houston. “But I don’t care what they say. It’s not about Brian Castano. This is the Charlos’ time.”
