WBO Championship Tripleheader Features Valdez, Ramirez, Magdaleno

Undefeated WBO world champions Oscar Valdez, Gilberto “Zurdo” Ramirez and Jessie Magdaleno will headline an exciting world championship event in separate title defenses, Saturday, April 22, under the stars at StubHub Center in Carson, CA.

Produced and distributed live by Top Rank Pay-Per-View, the telecast will also feature the pro debut of U.S. Olympic silver medalist Shakur Stevenson in a four round featherweight bout.

Valdez (22-0, 19 KOs), from Nogales, México, will be making the second defense of his WBO featherweight title against No. 1 contender and NABO champion Miguel “Escorpión” Marriaga (25-1, 21 KOs), from Arjona, Colombia.

Ramírez (34-0, 24 KOs), from Mazatlán, México, will be making his first defense of the WBO super middleweight title against Top-10 contender Max “Tiger” Bursak (33-4-1, 15 KOs), of Kiev, Ukraine.

Magdaleno (24-0, 17 KOs) of Las Vegas, NV, will be making the first defense of his WBO junior featherweight title against WBO Latino champion Adeilson “Dell” Dos Santos (18-2, 14 KOs), of São Paulo, Brasil, and Stevenson, the crown jewel of the 2016 U.S. Olympic team and the pride of Newark, NJ, will be making his eagerly awaited professional debut in a four round featherweight bout.

The six world championship warriors have a combined record of 156-7-1 for a winning percentage of 95% with a victory by knockout ratio of 71%.

“Óscar Valdez, Gilberto Ramírez and Jessie Magdaleno are becoming the new faces of boxing. They are in the hurt business and they love their work. That’s why their fan base is growing like the S&P, they give the fans great value, a big bang for the buck,” said Hall of Fame promoter Bob Arum. “And with Shakur Stevenson, the sky is the limit. He is such a talent.”

“Every fight is important to me. I respect Marriaga just like every fighter I face. And I will do whatever I have to do to win,” said Valdez. “This will be the second defense of my belt and I know the challengers are going to come after me, but I will be more than ready to give the fans a great fight and retain my championship.”

“Second chances are rare in boxing and I’m going to make the most of my second shot at a world title,” said Marriaga. “My trainer. ‘Professor’ [Samuel] Gómez and I will be prepared to give the performance of a lifetime on April 22.”

“Óscar Valdez Is boxing’s next big star. He’ll be defending his title at the StubHub Center in front of the Southern California fans who love him so much,” said Frank Espinoza, Valdez’s manager.

“He is an incredible talent and a future superstar. You have to see Óscar fight live. It’s always nice to catch a star on the rise so that someday you can say, ‘Hey I watched him back in the day,’ like they say about Julio César Chávez. Óscar Valdez is extremely driven and looking to be a legend. He’s ready mentally and physically for the next step.”

“I feel very happy and I’m thankful for the opportunity of defending my title for the first time,” said Ramírez. “I’m motivated and I feel a great desire to return to the ring. I have been active in my hometown of Mazatlán and training like if I was going to fight. Now I’m ready to fight!

“I feel 100% recovered from the injury in my hand. I feel better than ever and with more confidence in my punching power. On April 22 I will give the fans an explosive fight with lots of action.

“Max Bursak is a solid strong fighter. He is a brawler and he is coming with hunger of triumph for all the Ukrainians. It will be very good for three Mexicans to be defending our titles on the same card and even more here, in California, where there is a big boxing fan base.”

“Ramírez is young, tough and already an experienced fighter. But I’m also not an ‘easy walk’. We have almost similar records and achievements, so it’s going to be a very interesting clash,” said Bursak. “I’m already working hard in the gym, because I’m coming to California to win!”

“Gilberto is returning from an excellent recovery period after the surgery he had in one of the knuckles of his right hand. He has been very active, running and doing therapy in Mazatlan since the doctor cleared him last year,” said Jesus Zapari, Ramírez’s manager.

“After he was done with therapy, he started doing some conditioning training, until he was cleared to start punching. He is now a world champion who will not have any easy opponents. Zurdo has being training hard to keep improving with each fight. He now has more confidence in his punching power.

“We are very happy that the fight will be at StubHub Center in Los Angeles. We have always wanted to fight in that venue because of the great fans that are in Southern California. It will be a great night of boxing and Zurdo will put on a great show for the fans”

“To be a champion today you have to work hard every day, go after the big challenges and see the big picture,” said Magdaleno. “That is what I am doing to express myself and my legacy in the sport, going into a title fight like this one.”

“For me this is a unique opportunity, to be fighting for the world title of a very big entity that is the WBO,” said Dos Santos. “I know that Jessie is a very good fighter. He is a real champion. Fighting for the title has always been a dream for me and today it has come true.

“Thanks to my agent Patrick Nascimento and my promoter Edu Mello. I’m training very hard for this fight. I’m very focused. I know it will not be an easy job. For those who know me, on April 22, you will see a different Adeilson. I’m working to put on a big show and win the title.”

“Jessie Magdaleno fights April 22nd at the StubHub and I think the knowledgeable Southern California fans are going to get a glimpse of a very talented young champion,” said Espinoza, who also manages Magdaleno.

“He’s building a big fan base and I think the StubHub is the perfect place for him to develop. The fans are going to fall in love with this kid and his fighting style. He’s a real warrior an old school fighter who gives you everything. He’s a must-see fighter!”

“I’m excited to start a new chapter in my boxing career and make my pro debut on April 22 at the Stub Hub Center,” said Stevenson. “There have been so many exciting fights in that building and I plan to add to that history in my first pro fight. I’m already training hard and everyone is going to see what I’m all about on April 22, live on Top Rank Pay-Per-View.”

Valdez (22-0, 19 KOs), from Nogales, México, and who represented México in the 2008 and 2012 Olympics, was the first Méxican fighter to qualify for two Olympic games. He is considered one of the bright lights of the featherweight division and a new face for boxing’s next generation.

He will be making the second defense of the vacant world title he won on July 23, 2016 via a second-round knockout of undefeated No. 2 rated Matías Rueda. Rueda entered that fight having won his previous 10 bouts by stoppage.

Valdez, 26, started 2016 with a fourth-round knockout victory over former IBF featherweight champion Evgeny Gradovich on the April 9 Manny Pacquiao vs. Tim Bradley III pay-per-view undercard in Las Vegas.

It was the first time Gradovich had ever been stopped in his 24-bout professional career. In his last fight, on November 5, he successfully defended the title with a seventh-round TKO of No. 1 contender Hiroshige Osawa.

Marriaga (25-1, 21 KOs), from Arjona, Colombia, enters this fight having won 15 of his previous 19 fights by way of knockout. The only blemish on his record, a 12-round unanimous decision loss to former WBA featherweight champion Nicholas “Axe Man” Walters in 2015, who had lost the title on the scale when he weighed in over the division weight limit.

Since that loss, Marriaga, 30, has fashioned a five-bout winning streak, including NABO featherweight title knockout victories in his last two fights against Guy Robb and Eduardo Montoya last year to become the WBO’s No. 1 contender and mandatory challenger.

Ramírez (34-0, 24 KOs), a two-fisted super middleweight wrecking machine who hails from Mazatlán, México, made history in the co-main event to the Manny Pacquiao vs. Timothy Bradley welterweight pay-per-view on April 9, 2016, when he became México’s first fighter to win a super middleweight world title.

Entering the fight as the top world-rated contender, Ramirez gave a virtuoso performance over the defending WBO champion Arthur Abraham. All three judges scored it as a 120-108 blitzkrieg. “I took him to Méxican boxing school,” a jubilant Ramírez boasted as he put on the world championship belt .

A sensational young champion, Ramírez, 25, had been scheduled to make his first title defense last July, but a training camp injury to his right hand followed by surgery and rest sidelined him for the remainder of the year. He returns to the ring having won four of his last eight bouts by knockout.

Career-highlight performances include an NABF and NABO title victory over Giovanni Lorenzo via fifth-round stoppage, a WBO International title knockout victory over Junior Talipeau and a successful defense of his NABF and WBO International titles, stopping Fulgencio Zuniga in the eighth round, all in 2014.

In 2015, he successfully defended his titles via unanimous decisions over once-beaten Maxim Vlasov, division gate keeper Derek Edwards, who boasts a KO victory over world champion Badou Jack, and once-beaten Gevorg Khatchikian, who had scored knockouts in five of his last six victories.

Bursak (33-4-1, 15 KOs), from Kiev, Ukraine, will be making his U.S. debut. A former European middleweight champion and one-time WBO interim middleweight world title challenger, Bursak, 32, enters this fight having scored three of his last four victories by way of knockout and is world-rated No. 10 by the WBO.

Magdaleno (24-0, 17 KOs), from Las Vegas, NV, enters his first title defense having won eight of his last 11 bouts by knockout. The former U.S. Amateur Champion has crafted a sterling professional ring record since making his professional debut on November 6, 2010.

The younger brother of lightweight contender Diego Magdaleno, Jessie, 25, parlayed his No. 1 ranking into a mandatory challenge of defending WBO junior featherweight champion and five-division world titlist Nonito “Filipino Flash” Donaire on November 15, 2016, winning a very close and action-packed 12-round unanimous decision.

Dos Santos (18-2, 14 KOs), from São Paolo, Brasil, has won five of his last six fights by stoppage. He captured the WBO Latino featherweight title on September 17, 2016, knocking out Deivis Perez in the seventh round. Dos Santos, 25 who has also held the WBO Latino junior featherweight title, will be making his U.S. debut on this card.

Stevenson, 19, from Newark, NJ,, sailed though every stage of his Olympic competition in Rio De Janeiro last summer before losing a close split decision in the bantamweight championship fight to 2012 flyweight Olympic gold medalist Robeisy Ramirez of Cuba.

Ramirez swept the judges’ scorecards in round one with Stevenson returning the favor in round two. In the third and final round, the closest of the three rounds, two of the three judges gave the round to Ramirez and the gold medal, by the slimmest of margins. It was the best finish for an American male boxer since Andre Ward captured the gold medal in the Athens Games of 2004. Ward is now part of Stevenson’s management team along with James Prince and attorney Josh Dubin.

The only boxer to make Forbes “30 Under 30” in its Sports category, Stevenson was selected by a panel of judges comprised of James Harden, shooting guard for the Houston Rockets, Phil Knight, Chairman Emeritus of Nike and Casey Wasserman, Chairman and CEO of the Wasserman Group.

The oldest of nine children, Stevenson, who is named for the late rap star Tupac Shakur, was introduced to boxing by his grandfather, Willie “Wali” Moses, at age 5. Now based in northern Virginia, Stevenson is trained by Kay Koroma.
