ROBERTO Diaz left Golden Boy Promotions having, as one of the worldโs leading matchmakers, long been so crucial to their success. During a potentially defining time in their short promotional history, his influence can perhaps even still be felt. By Declan Warrington.
The fight between Saul โCaneloโ Alvarez and John Ryder, in Guadalajara on Cinco de Mayo weekend last year, came weeks after Roberto Diaz had suffered a heart attack, and yet the respected matchmaker was ringside โ watching, and absorbing โ having travelled from Los Angeles to be present.
He was joined there his wife Carla, who has long worked for the worldโs leading fighter. Weeks later he then watched from afar when Jaime Munguia narrowly outpointed Sergiy Derevyanchenko and with particular interest, given he had also contributed so much to Munguiaโs career before Diazโs departure from Golden Boy Promotions earlier in 2023.
Throughout his 15 years with Golden Boy, he had come to be recognised as one of the worldโs finest matchmakers, and an essential figure at a promotional organisation that for a period was widely considered the most powerful in the world. Ryan Garciaโs recent victory over Devin Haney has strengthened their interests even more than perhaps would Munguia defeating Alvarez or Vergil Ortiz Jnr beating Tim Tszyu, but even then they may not again rediscover the heights reached previously, when the super fights and the presence of Oscar De La Hoya, Bernard Hopkins, Shane Mosley, Ricky Hatton and more gave them such appeal.
It was Diaz, through his long-term association with Marco Antonio Barrera, who before joining Golden Boy had put Hatton in contact with De La Hoya and De La Hoyaโs then-partner Richard Schaefer, ensuring that the fight between Hatton and Floyd Mayweather was made. Mayweather, by then, had already defeated De La Hoya on another Golden Boy promotion; the two biggest fights of 2007 were ultimately theirs.

If it was also through Barrera that Golden Boy and other fighters first became aware of Diaz, it is since his separation from the Mexican that his reputation has grown. Like Barrera โ and indeed De La Hoya, Hopkins and Schaefer โ he may never again be quite so influential, but like so many others who worked alongside or against him, he will forever know how responsible he was for so many fine fights being made.
To learn the full picture of Diazโs 55 years is to learn of a lifetime before his meeting with Barrera. Of the trappings of gang culture in San Francisco, where he was born, and his father forcing him to relocate to the Yucatan region of Mexico where it was beyond him; of his occupations as a salesman and as a parole officer; of the life-threatening car crash and successful battle against cancer that saved his marriage on account of the commitment Carla continued to show him when they had previously decided that they should divorce.
It is perhaps for those reasons that the perspective Diaz has gained โ his most recent health scare followed his departure from Golden Boy โ is even more acute. By his own admission there were times his family was neglected while he pursued what he describes as his โdreamโ. Perhaps the demands of his profession and the rate at which Golden Boy was growing even means that was the only way that it could ever have been.
โThatโs what I learned after the 15 years when we parted ways,โ he tellsย Boxing Newsย from his home in LA. โAnother message is first is your health; second is your family, and third is your job, because your jobโs always going to be there as long as they need you. Family has to be there.
โI donโt want to sound like I regret it, because it got me to where I am and who I am today, but you gotta give your family that importance, and there were times โ โIโm sorry; I canโt make it to thatโ โ because work comes first. There was a [Barrera] fight. I was in camp. My father [Roberto] had been sick for 30 years. They depend on me โ I gotta be here.โ โMan, I should be going โย when the fightโs over Iโm gonna head out.โ He passed away the morning of the fight. One more day, I probably would have saw him. Marco โ his whole family โ everybody knew. Marco gets cut, so after the fight I rush him to get stitched up. We get back to the hotel. The poolโs reserved for an afterparty. Everybodyโs with this long face. I turn around, and Carlaโs sobbing. โMy dad died, huh?โ In retrospect, the job was always first.โ
Barreraโs faith in Diaz โ first following their meeting at a shopping centre in San Diego, where Diaz then lived, then when he fought Cesar Najera in Fantasy Springs โ led to an invite to join his training camp in Big Bear, California, for his unforgettable first fight with Erik Morales. The commitment Diaz showed contributed to him later being so instrumental towards the timing of the third fight of their trilogy โ Barrera secured his second victory over his greatest rival โ Diazโs reputation growing, and eventually the offer to be the assistant matchmaker to Eric Gomez.
โIn probation I worked a week and rested a week, so Iโd go up for a couple of days and spend it in camp; run with them; eat with them,โ he recalls. โEventually, from being a fan; a friend, [Barrera] says, โWhy donโt you go in with the flag for my next fight?โ. They went on to have an amazing trilogy.
โโIโm gonna sign with Oscar De La Hoya; Golden Boy Promotions.โ Golden Boy was just starting; [outside of De La Hoya] Marco was their biggest name. โWeโve got our first fight, against Manny Pacquiao.โ Weโre in Big Bear, and what I saw was a fast, young fighter that had a lot of trouble with the jab. Marco had a beautiful jab โ a power jab, because heโs a southpaw converted. โI donโt see anything better than Naseem Hamed. Naseem was more awkward; punched harder.โ Fast forward, a hall-of-fame, tremendous fighter โย amazing fighter โ and something that comes around once every 100 years. But at the time he didnโt seem anything special.
โHe loses this fight, and Iโm thinking โItโs overโ. Oscar didnโt cut him; Golden Boy didnโt cut him. Brings him back. From that point on, it was me. I saw Erik Morales have two of his toughest fights the following year and I say, โMarco, you need to fight the third fight nowโ. I didnโt doubt myself in that fight. That win basically put Golden Boy on the map.
โStepping back, the majority of the fans will tell you [Juan Manuel] Marquez was number one, theyโll probably say Barrera, because he beat Morales twice, was number two, and Morales was number three. Even though the results speak for themselves, I would really almost say Morales was number one, Marco number two, and Marquez number three.
โRemember, Iโm with Marco. โLetโs call it a day.โ Heโs a partner at Golden Boy. โLetโs focus on the promotion and the young kids.โ He had other plans [he again fought, and lost to, Pacquiao in 2007]. Thatโs a fighter always being who they are.โ
There started the even-more-transformative decade and a half with Golden Boy โ and the evolution of the promoterโs reputation from one that worked with proven champions to one who guided them from the start. Diaz relocated to LA from Sacramento, where his family remained, to accept the offer of working with Gomez, but he considered quitting after each of the first two promotions he oversaw.
โOh my god,โ he says. โThey expanded; from one day to the next, and thatโs why it was like a crash course. Youโre gonna sink or swim. Bernard Hopkins beating [Kelly] Pavlik; it was an amazing time. Everybody wanted to be with Golden Boy. There was a knock on Golden Boy before I got there that if you were a star, already made, thatโs where you would go. โBut donโt go as a young fighter, because they donโt know how to build fighters.โ They had Mosley; Hopkins; Marquez; Barrera; established fighters, maybe close to retirement, but had never produced a world champion. That knock, a few years later with enough time and growth, was gone, because of Abner Mares; [Daniel] Ponce de Leon; Danny Garcia; Adrien Broner; Deontay Wilder; [Jermell] Charlo. That knock quickly went away. I take a lot of pride in it, because I started the careers of a lot of them. I did almost 99 per cent of Wilderโs fights.
โDonโt take it that it was all gravy โ I remember a nasty email coming in blaming me for Victor Ortizโs loss against [Marcos] Maidana. Thatโs when I learned you gotta have a thick skin. When they win itโs the fighter; the team; the promoter; never the matchmaker. When they lose itโs the matchmaker. It was very intense; fun. But it wasnโt made for the average Joe. There were times there were three shows on the weekend. Thatโs how busy the time was.
โRichard did a hell of a job. In retrospect I see maybe what Richard saw at the time. Maybe I didnโt see it as clear. โMaybe thatโs what he saw that he didnโt like.โ But I donโt think Richard and Oscar splitting is why the company changed. The Yankees had an era where they were the number-one team. Itโs part of evolution; itโs part of growth. It happens in boxing a lot more.
โThereโs no such thing as the perfect show โย thereโs always going to be something that goes wrong. Youโve gotta go on with the show.โ

Through Garcia, and potentially Munguia and [Vergil] Ortiz, Golden Boy are rebuilding. There previously was heartache for Diaz โ โThe Mayweather loss was devastating, because I really believed [Hatton] would beat Mayweatherโ; a since healed fallout with Barrera; watching Frankie Gomezโs talent go to waste โ and then, even more significantly for he andย each of his colleagues, the withdrawal from boxing of HBO.
โWhen the split [between De La Hoya and Schaefer] happened, it really slows down, because the big name you have is โCaneloโ,โ says the Mexican, whose son Bobby remains with the promoter and also works for DAZN. โHe sticks with Golden Boy; all your other fighters are gone. A lot of them werenโt under contract; they leave; along with them leaves networks; Canelo stays; HBO signs Canelo to a long-term deal; that saves us for a time.
โHBO all of a sudden decides to get out of boxing โ a huge blow to everybody. Fighters; promoters; boxing in general. You still go back and reminisce and watch some old fights on HBO. They were the best. โOkay. What are we gonna do?โ I was a lot to do with the fighters, one-on-one. Not that anyone else wasnโt, but they knew that they could pick up the phone anytime. I wanted to be involved; I wanted to be close to them. Youโve got champions youโre going to have to let go. โBut you gave me your word.โ I never foresaw Covid and where all this was going.โ
Since Alvarezโs departure, Golden Boy have been working with DAZN. Had Diaz not refused to promise Dmitry Bivol a fight with Alvarez, he believes that they would be promoting the Russian, whose potential he identified. Diaz was in Las Vegas to watch Bivol-Alvarez in 2022; when he watches Alvarez-Munguia he will be far from dispassionate; as recently as June 2023 he was responsible for Danielito Zorrilla replacing the injured Liam Paro as the opponent for Regis Prograis.
โFifteen years,โ he says. โIt wasnโt easy โ people became accustomed to my name getting tagged along with Golden Boy. But my contract ended โ every beginning has its end. It was time for both sides to go their way; maybe down the line things will start coming out little by little. How things ended maybe werenโt the best, or at least done the right way. I donโt regret the 15 years โ the 14.5 were amazing.
โOnly a matchmaker understands the other matchmakers. I want to stay in boxing. Thatโs my passion. Iโm good at it โย itโs what I want to do. But in a different role. Let me sit back; advise; do here and there.
โI can see both sides now; itโs not just being a manager that says, โYou gotta pay moreโ. I know where the middle is.โ
