The Great Boxing History of Stockton, California
For over a century, Stockton has been a venue for the country's historic top fighters.
Johnson. Braddock. Louis. Marciano. Ali. Ward. Tyson. Mayweather. Just a few of the legendary names that made the "sweet science" arguably the most important sport in the nation.
Boxing, as well as mixed martial arts and full-contact, body-to-body sports, continue to grow in popularity today. They sell out arenas, break pay-per-view records, and carry a buzz like nothing else. Whether it's the Olympics, Las Vegas, or a local auditorium, you're bound to find a fighting venue with a loyal fanbase. Major cities like New York, Boston, and Philadelphia have their great, well-earned "fighting town" tales, but they aren't the only ones known for breeding and housing great champions. Here's a look back at Stockton's own boxing city tales.
"Pop, Pop, BANG!"
Stockton has a rich boxing history, dating back to the opening of its first open-air boxing arena at Oak Park in August 1922. That park's arena would later host boxing legend Max Baer’s 1st professional fight on May 16, 1929. Today, Oak Park is home to an ice rink, a tennis court, and Billy Hebert field—the former home of the Stockton Ports.
Trivia fact: Billy Hebert was the first baseball player to die while serving in World War II. Stockton named Billy Hebert Field in his honor.
Stockton Memorial Civic Auditorium would house its first fight card on June 30, 1930, drawing nearly 2,000 people in attendance. In 1932, a Jack Dempsey/Bad News Johnson showdown would bring in over 3,500 people, while Filipino star boxer Bayani Garcia’s US debut would draw over 4,000 inside the venue. Today, the Stockton Memorial Civic Auditorium hosts various events, including festivals and live music, while also serving as a venue for "fight night" with 209 Beatdown.

Stockton-born fighters would also make an impact in these early years. Fred Feary won the bronze medal at the 1932 Olympics in Los Angeles, while Jesse Flores became the first Stockton boxer to fight inside Madison Square Garden in NYC, fighting to a draw with Johnny Williams in 1948. Flores would go on to win the rematch in June of that year.

On April 30, 1959, Stockton's own Amos Johnson scored a victory against a young Muhammad Ali, then known as Cassius Clay. The win gave the local fighter the light heavyweight title in the U.S. Pan American trials. Johnson would go on to win the Pan Am gold in Chicago that September.
Trivia fact: The novel "Fat City" by Leonard Gardner, published in 1969, became an instant boxing classic, focusing on Stockton's fighting scene. In 1972, the film adaptation—shot right here in Stockton—hit theaters, directed by John Huston and starring Stacy Keach, Jeff Bridges, and Susan Tyrrell.
We can’t talk about the great fighting spirit that is rooted in this city without including the great Alvaro “Yaqui” Lopez. Lopez thrilled fans with epic, thrilling bouts that went down in history—including his July 13, 1980 showdown with Matthew Saad Muhammad for the WBC light heavyweight title in New Jersey. That fight was named the "Fight of the Year" by Ring Magazine. With Stockton as his adopted home, Lopez went on to form the Fat City Boxing Club, located on East Miner Ave. Lopez's spot provides a space for underprivileged youth to positively channel their energy into sport and competition, steering them away from negative influences.
And of course, everyone knows Nick & Nate Diaz—the MMA icons who proudly call Stockton & the 209 their home. While the Diaz brothers are known for their elite MMA skills, Nate stepped into the boxing ring, where he defeated UFC rival Jorge Masvidal by majority decision on July 6, 2024, at the sold-out Honda Center in Anaheim, California.


In 2023, our city continued its legacy as a fighting town as “Stockton’s King” Gabriel Flores, Jr. came home to the Adventist Health Arena for his May 13th bout against Derrick Murray, where he won via knockout in 27 seconds. The following year, Flores, Jr. returned home on March 16 to beat Julian Rodarte and win the WBA Continental Title.
In July of 2024, Gabriel Flores, Jr. successfully defended his WBA Continental Title against Ronal Ron at the “Slugfest in Mudville” at the Stockton Ballpark—the first fight card ever held in the home of the Stockton Ports. Then in October of that year, Flores, Jr. went on to defeat Dennis Contreras at the "Nightmare in the Arena" at Adventist Health Arena.
