Ruiz had
Freddie Roach in his corner and at the Wild Card Gym and sparred with former
UFC heavyweight champion,
Andrei Arlovski. Ruiz mostly fought journeymen opposition earlier in his career but did knock out two amateur stars in
2006 US amateur champion Jonte Willis and
2008 Golden Gloves champion Tor Hamer.
Early career A 19-year-old Ruiz made his professional debut on March 28, 2009, at the
Plaza de Toros in
Tijuana, Baja California, Mexico, in a four-round bout against Miguel Ramírez. Ruiz won the fight via a first-round
knockout (KO). Ruiz fought again after three months at the same venue, this time knocking Ross Brantley down three times in round one, winning the bout via
technical knockout (TKO). Ruiz took an eight-month gap before he returned to the ring in February 2010, winning a four-round
unanimous decision against Juan Luis Lopez Alcaraz. A month later, Ruiz made his American debut at the
Gaylord Hotel in
Texas, knocking out Luke Vaughn in round one. Ruiz had his next three fights of 2010 also in the U.S., defeating Miles Kelly via KO, Raymond Lopez via unanimous decision and Francisco Diaz via KO. On February 5, 2011, Ruiz knocked out Kelsey Arnold in the third-round and in the same month defeated Alvaro Morales via unanimous decision 59–55, 59–55, and 60–54. In April 2011, Ruiz defeated Angel Herrera via six-round unanimous decision. In July, Ruiz fought at the
Texas Station Casino,
Las Vegas, defeating Villi Bloomfield via fourth-round TKO. He returned to the Casino on December 7 and defeated
Elijah McCall (11–1–1, 10 KOs), son of former world champion
Oliver McCall, by a TKO one second before round three ended. Referee Kenny Bayless waves off the fight after McCall stopped defending himself. Ruiz's hand speed was showcased in this fight. On March 23, 2012, Ruiz fought his first eight-round fight, outpointing Homero Fonseca. All three judges scored the fight 80–72. In July, Ruiz fought
Jonte Willis (8–3–1, 3 KOs) at the
Home Depot Center,
Carson, California. Willis entered with a record of 1–3–1 in his previous five fights, including a
split decision loss three months prior to
Denis Bakhtov (33–7). Ruiz floored Willis in round five from a short right hand before referee Wayne Hedgpeth stopped the bout in round eight, after a combination of unanswered punches. This was on the undercard of Donaire vs. Mathebula.
Rise up the ranks On July 27, 2013, Ruiz traveled to
Macau with
Top Rank to fight at the
Cotai Arena against undefeated 30 year old American
Joe Hanks (21–0, 14 KOs) in a scheduled ten round fight. Ruiz dropped Hanks twice in round four with fast right hands, forcing the stoppage. Ruiz claimed the vacant
WBO Inter-Continental heavyweight title with this win. On November 24, Ruiz fought again the Cotai Arena, this time on the
Pacquiao-Rios undercard, successfully defending his WBO Inter-Continental heavyweight title and claiming the vacant
WBC-
NABF heavyweight title defeating
Tor Hamer (21–2, 14 KOs). The fight was stopped after the third-round when Hamer indicated he did not wish to continue. Over the three rounds, Ruiz landed 74 of 213 punches thrown (35%) and Hamer landed 49 of his 131 thrown (37%) before he
quit on his stool. This was the second time Hamer had retired on his stool following his previous loss to
Vyacheslav Glazkov in December 2012. His promoter
Lou DiBella announced Hamer had been released from his contract. On December 20, 2014, Ruiz fought former WBO heavyweight champion, 38 year old
Siarhei Liakhovich (26–6, 16 KOs) at the
Celebrity Theater in
Phoenix, Arizona. Ruiz was taken to the ten round distance for the first time in his career by Liakhovich, who trained hard for this fight and tried to win. The scorecards read 98–92, 96–94, and 99–91, all in favour of Ruiz who retained his titles. This was the last time Liakhovich fought. Ruiz revealed he fractured his right hand during the second round. In June 2015, Ruiz began training with well-known trainer
Abel Sanchez, whose most notable boxer was
Gennady Golovkin. After a 9-month gap, Ruiz returned to the ring in September 2015 at the
Tachi Palace Hotel & Casino in
Lemoore, California, defeating Joell Godfrey via unanimous decision over eight rounds, all three judges scored it 80–72. Godfrey was a late replacement for
Devin Vargas, who was unable to obtain a license from the California Athletic Commission. A month later, Ruiz fought veteran Raphael Zumbano Love (37–11–1, 30 KOs). Ruiz won on points after eight rounds. On May 14, 2016, Ruiz fought 45 year old, former world title challenger
Ray Austin (29–6–4, 18 KOs) at the
Sportsman's Lodge in California. Austin weighed 18 pounds more than Ruiz at the weigh-in. This was the first time in 14 professional fights that Ruiz was outweighed by his opponent. This was Ruiz's fourth successful defence of his WBC-NABF heavyweight title as Austin was down in round one, he injured his right hand and failed to come out of his corner for round five. After this bout, Ruiz increased his record to 27 wins in as many fights. Ruiz fought on July 16 against 42 year old Josh Gormley (22–4, 21 KOs) at the
Masonic Temple in
Michigan. Promoted by
Salita Promotions. Ruiz won the fight via third-round TKO. Ruiz next fought on September 10, 2016, returning to the
Tachi Palace Hotel & Casino in California to headline "Solo Boxeo Tecate" (UniMas) against 40 year old Franklin Lawrence (21–2–2, 16 KOs) for the WBC-NABF heavyweight title. Lawrence had won his last nine fights inside the distance dating back to 2009, with his last loss being against veteran
Oliver McCall. His only other loss came in his fifth professional fight against future WBC world champion
Bermane Stiverne, which was stopped after Lawrence injured his arm in round one. Ruiz made a successful fifth defence of his WBC-NABF title after ten one-sided rounds. The judges scored the fight 100–90, 99–91, and 99–91. The win also set up a future WBO eliminator with bout with
Hughie Fury. It was announced after the Lawrence fight that Ruiz would fight Hughie Fury in the UK on October 29 at the
Manchester Arena, on the undercard of the
cancelled rematch between Tyson Fury and Wladimir Klitschko. The winner would be the
mandatory challenger for the WBO heavyweight title. Two weeks later, it was reported that Ruiz had withdrawn because he did not want the fight.
WBO heavyweight title challenge Ruiz vs. Parker Ruiz was ordered to fight
Joseph Parker in
New Zealand for the WBO heavyweight title with the fight set to take place on December 10, 2016. This fight came about by Ruiz being one of the top two ranked contenders willing to fight for the vacant title. The title became vacant when former champion
Tyson Fury vacated the title. Discussions and negotiations began after Fury was expected to be stripped of his WBO belt over inactivity and testing positive for
cocaine. With his sudden announcement that he would relinquish his heavyweight world title belts due to his various issues, it was unclear exactly how the WBO and
WBA would go about filling the vacancies. But before Fury vacated,
Duco Events promoter Dean Lonergan announced in early October he had been negotiating an alternative WBO title fight against Ruiz, suggesting he had a chance of reaching a deal with
Bob Arum. He pointed out that the WBO rules stated the two best-classified contenders will challenge for the title. Arum told
ESPN.com that he was in talks with the WBO about making it for the vacant title. Ruiz failed to become the first heavyweight of Mexican ancestry to win a world title when Parker won the bout by a
majority decision. The judges scored the fight 114–114, 115–113, and 115–113. Ruiz started off well being the aggressor but slowed down during mid rounds, only to take control again during the championship rounds. Both men showed respect for each other throughout the contest. After the fight, Ruiz said, "I think I got the win or at least a draw, I think I set the pace with my jab." Ruiz said he wanted a rematch.
CompuBox stats showed that Parker landed 119 of 560 punches thrown (21%) and Ruiz landed 107 of his 416 thrown (26%). On a delayed
HBO broadcast, the fight peaked at 585,000 viewers, with an average of 521,000 viewers.
Winning streak in 2018–2019 Ruiz vs. Vargas On December 19, 2017, Angel "Memo" Heredia, a well known strength and conditioning trainer, confirmed that he would be working alongside Ruiz. Ruiz was next to make a ring return on February 3, 2018, on the undercard of
Gilberto Ramirez vs. Habib Ahmed WBO
super middleweight title fight at the
American Bank Center in
Corpus Christi, Texas. Ruiz did not appear on the card and instead his return was pushed back to take place at the
StubHub Center in Carson, California on the undercard of
Óscar Valdez vs.
Scott Quigg on March 10. In his absence from the ring, he explained, "I just wanted to take a break. I already have 30 fights. I wanted to be with the family, I started investing my money. I started building houses. But every boxers needs that little break and now I've got to come back harder." American boxer
Devin Vargas (20–4, 8 KOs) was confirmed as his opponent in a scheduled eight round bout. Ruiz knocked Vargas out in round one. He landed a big right hand to the head of Vargas, dropping him. Referee Thomas Taylor called off the fight. The official time of the stoppage was at 1:38 of round one. Ruiz showed good power and speed during the short fight. For the bout, Ruiz trained with Manny Robles. Ruiz received a $500,000 purse.
Ruiz vs. Johnson His next fight was scheduled to take place on July 7, 2018, at the
Save Mart Center in
Fresno, California, against former world title challenger
Kevin Johnson (32–9–1, 16 KOs). The main goal for this bout was for Ruiz to get in some much needed rounds, having only completed less than a round in over a year. Johnson, who had previously only been stopped twice in his nine losses, was known for his toughness, having taken the likes of
Kubrat Pulev,
Derek Chisora,
Tyson Fury and
Vitali Klitschko the twelve round distance. Ruiz dominated Johnson over ten rounds, winning via unanimous decision with scores of 99–91, 97–93, and 97–93. Johnson did not do much apart from throw a strong jab from time to time. It was Ruiz who was busy and remained in control for majority of the bout. Ruiz admitted it was good to go the distance and called out some of the better heavyweights, namely
Jarrell Miller.
Ruiz vs. Dimitrenko On January 11, 2019, it was reported that Ruiz had signed a deal with powerful advisor
Al Haymon, and would now be part of the
Premier Boxing Champions (PBC) stable, with his fights being aired on
Showtime and
FOX. It was said that Ruiz had bought out the remainder of his
Top Rank promotional contract. On March 7, Ruiz's PBC debut was announced to take place on the
Danny García vs.
Adrián Granados undercard on April 20 at the
Dignity Health Sports Park in Carson, California against 36 year old German boxer
Alexander Dimitrenko (41–4, 26 KOs) in a ten-round bout. The fight was televised on FOX and
FOX Deportes. For the fight, Ruiz weighed 262 pounds and Dimitrenko came it at 259 pounds. Ruiz was guaranteed a $200,000 purse, whilst Dimitrenko was guaranteed $75,000. Using his quick hands and combinations, Ruiz was able to overcome Dimitrenko via TKO in round five. The bout nearly came to an end in round four when Ruiz nearly knocked Dimitrenko down, however Dimitrenko managed to make it to the end of the round. Ruiz landed 68 punches overall, compared to Dimitrenko, who landed 21 punches. For his next fight, Ruiz wanted to fight
Adam Kownacki.
Unified heavyweight champion Ruiz vs. Joshua Prior to the Dimitrenko fight, Ruiz put his name forward to replace
Jarrell Miller and challenge
Anthony Joshua (22–0, 21 KOs) for the
unified WBA (Super),
IBF, WBO, and
IBO heavyweight titles on June 1, 2019, after Miller was denied a license by the
New York Athletic Commission because he failed three different tests for
PEDs. On April 22, Ruiz confirmed his team had a meeting scheduled with promoter
Eddie Hearn, officially putting himself in the running. Ruiz became a frontrunner after it was reported
Luis Ortiz's team had rejected two offers of career-high purses to fight Joshua. Terms were agreed within a week. On May 1, with one month to go before fight night, Joshua vs. Ruiz was confirmed and announced to take place at
Madison Square Garden in
New York City, broadcast exclusively on
DAZN in the United States and on PPV
Sky Sports Box Office in the United Kingdom. On June 1, Ruiz defeated Joshua by technical knockout in the seventh-round, capturing the unified WBA (Super), IBF, WBO, and IBO titles. In the third round, Joshua knocked Ruiz to the canvas, which was the first time Ruiz had suffered a knockdown in his career. Ruiz rose to his feet and continued to attack. Ruiz landed a left hook to Joshua's temple which visibly staggered him, after which Ruiz knocked him down. Just before the end of round three, Ruiz again knocked down Joshua after forcing him into a corner and unleashing a series of power punches. In round seven, Ruiz knocked Joshua down once again. Joshua managed to get back on his feet again before being floored for a fourth and final time, resulting in the referee waving off the fight. The referee subsequently awarded Ruiz a seventh-round technical knockout victory, making him the first
Mexican-American and second
Hispanic heavyweight champion in boxing history after
John Ruiz (who has no relation to Andy Ruiz). At the time of stoppage, Ruiz was leading the fight 57–56 on two scorecards and Joshua was leading 57–56 on the other. It is considered to be one of the biggest upsets in the history of boxing.
Ruiz vs. Joshua II In September 2019 it was announced that Ruiz would defend his titles against Joshua in a rematch. The fight broke the UK
PPV record, totaling 1.575 million buys in the UK. The fight was a low-key affair in which Joshua mainly stayed behind his jab. Joshua boxed a disciplined fight, keeping Ruiz at a distance with his jab and using lateral movement to avoid trading punches up close as he had in their first encounter. He started off well, landing a sharp right hand in the first round that cut Ruiz to the side of his left eye. Joshua continued to box economically and land the more meaningful punches. Ruiz had some success when he tagged Joshua to the head and body at the end of the fourth round, but Joshua remained firmly in control of the action. Ruiz lost the fight via unanimous decision, with the three judges scoring the bout 118–110, 118–110, and 119–109. In his post-fight interview, Ruiz admitted that he hadn't trained diligently for the fight, stating, "I should have taken this fight more seriously. Three months of partying and celebrating affected me." In addition, he showed respect to Joshua, saying "Anthony Joshua did a hell of a job."
Post-title career After the loss to Joshua, Ruiz left his trainer, Manny Robles. He hired Eddy Reynoso as his trainer in May 2020.
Ruiz vs. Arreola In his first fight since losing his world titles, Ruiz faced former
WBC title challenger
Chris Arreola on
Fox PPV on May 1, 2021. This was his first fight with his new trainer Eddy Reynoso in his corner. Ruiz recovered from a second round knockdown to win a unanimous decision with scores of 118–109, 118–109, 117–110.
Ruiz vs. Ortiz Ruiz left Eddy Reynoso and started training with Alfredo Osuna. Sixteen months after defeating Chris Arreola, Ruiz returned to the ring on September 4, 2022, in Los Angeles to face former
WBA interim heavyweight champion
Luis Ortiz in an eliminator for the
WBC title. Despite being outboxed by Ortiz for portions of the fight, Ruiz dropped his opponent three times, twice in the second round and once in the seventh. The knockdowns proved to be decisive, with the judges scoring the bout 114–111, 114–111 and 113–112 in Ruiz's favor. Former WBC champion
Deontay Wilder had been in attendance, and both Ruiz and Wilder welcomed the prospect of facing each other.
Ruiz vs. Miller Ruiz had surgery to repair the rotator cuff in his right shoulder. He had been inactive for 23 months before his next fight. On April 24, 2024, a press conference was held at the Gotham Hall in Los Angeles to announce
Riyadh Season's debut card in the United States, which was to take place on August 3 at the
BMO Stadium in
Los Angeles. The headline was
Terence Crawford vs.
Israil Madrimov in a super welterweight title fight. Ruiz was announced for the card, in a crossroads fight against American heavyweight
Jarrell Miller in a 12-round heavyweight co-feature bout. There was no trash talk from Miller towards Ruiz. Instead, Miller said he would go for a pint after the fight was over. For Miller, the fight was not personal, however he stated that he would make Ruiz pay, for replacing him and taking his purse against Joshua. Miller weighed 305.6 pounds, however according to
California State Athletic Commission, was 312 pounds on fight night. Ruiz weighed 274.4 pounds, and gained a pound before the fight took place. The fight ended in a
majority draw: one judge scored the bout 116–112 to Miller, but was overruled by the other two judges who scored it a 114–114 draw. Miller started slowly, but after three rounds, Ruiz looked tired and did well to still go the distance. Miller was the more aggressive fighter and in control of the pace of the fight. He was pushing the action against Ruiz. Ruiz was limited in his offence, and Miller exploited this by piling on sustained pressure. During the last ten seconds of every round, Miller threw flurries. This was most likely a tactic by Miller to take rounds in his favour, as he was not able to be active for the full three minutes of each round. Ruiz's right hand appeared to be fractured during the fight with notable visual deformity to the contour of his metacarpal region shown in the post-fight interview. In his post-match interview, Miller asserted his opinion that he won the fight: "I know I did enough to win, I threw more punches. I had him backing up the entire fight. It's called effective aggression. I kept the pressure on and I hit him with the more effective punches. I had the fight in the bag." Fans on social media were also critical of scoring, feeling Ruiz's career was saved by the judges. Speaking further on the result, Miller said, "That's boxing; sometimes you get robbed. I just want the fans to keep supporting me; I've been an underdog my whole life." Miller said he was against having judges from the West Coast for the bout. According to
CompuBox, Miller landed 183 of his 514 punches thrown (35.6%) and Ruiz landed 113 of his 355 punches thrown (31.8%). Ruiz was more active during the first four rounds out-landing Miller 47–40. Miller landed double digits in every round from the third. Ruiz posted a picture of his injured right hand on social media, saying it affected his performance. It was believed to have been injured in round 5. ==Personal life==
