Xander Zayas – boxing’s youngest male champion at 23 – is set for his high-profile homecoming.

The WBO junior middleweight champion Zayas (22-0, 13 KOs) is set to square off against WBA crown holder Abass Baraou (17-1, 9 KOs) in a title unification bout on January 31 at Coliseo de Puerto Rico in San Juan, Puerto Rico, Top Rank announced on Monday.

The Ring reported last week that an agreement had been reached; a press conference is scheduled for Wednesday in Puerto Rico to begin building up the bout. Zayas is The Ring’s No. 6-rated fighter at 154 pounds while Baraou is No. 10.

“On January 31, we'll fulfill another dream,” Zayas said in a statement. “This time, I'll be fighting on my island. I'm going to unify two world titles in front of my people at Coliseo de Puerto Rico. We're going to make history together.”

Zayas captured the vacant crown he now carries by besting Jorge Garcia by unanimous decision in July. The WBO title was vacant once the sanctioning body stripped Sebastian Fundora in May. Fundora decided to defend his 154-pound WBC title in a rematch against Tim Tszyu instead of moving forward with his mandatory challenger and ordered bout against Zayas.

“From the moment Xander Zayas won his world title, it was clear that his first title defense had to take place in Puerto Rico,” said Top Rank boss Bob Arum. “The fact that he’ll be facing a fellow champion in front of a packed arena in San Juan makes it that much more special. The Puerto Rican fans are passionate and loyal and deserve to see their champion return home. This is not a routine title defense. Abass Baraou is a determined champion, an experienced road warrior who will embrace the challenge of fighting on Xander’s home turf.”

Baraou, a 31-year-old from Germany, set himself up for the sizable opportunity after scoring a unanimous decision against Yoenis Tellez in August. Baraou won the WBA interim title at the time and was elevated as the sanctioning body’s full titleholder in September after Terence Crawford left the division to face Canelo Alvarez.

“Xander is a great talent, and I give him full credit for stepping up and accepting this fight,” said Baraou. “Not everyone would take that risk, especially at this stage, but that’s what makes this matchup special. He has his country behind him, and I respect that, because I know what it means to carry that responsibility into the ring.

“I’m preparing to go into Puerto Rico, bring some real heat, and show the world that I’m a true force in this division. I’m not coming just to show up. I’m coming to make a statement, leave with another belt, and maybe even earn a few new Puerto Rican fans on the way out. When it’s all said and done, the world will know who the top dog at 154 really is.”

Also set to be featured on the card is second-generation upstart and junior bantamweight prospect Juanmita Lopez De Jesus (4-0, 2 KOs) in a six-rounder against a yet-to-be-determined opponent.
