LOS ANGELES, CA – Mexican boxing has produced generations of champions, but every era has fighters who add something different to the country’s sporting legacy. Gilberto “Zurdo” Ramírez is one of them.
His journey began in Mazatlán, Sinaloa, where he was born in 1991. Ramírez entered boxing at just 12 years old and developed his career while facing the economic challenges of his youth. Before the world championships and international arenas, he worked in construction to help his family.
Boxing eventually offered him a different path.
In 2016, Ramírez reached one of the defining moments of his career. At the MGM Grand in Las Vegas, he defeated Arthur Abraham by unanimous decision and became the WBO super middleweight champion.
The victory carried historic significance: Ramírez became the first Mexican-born fighter to capture a world championship at 168 pounds.
Rather than defending that achievement indefinitely, he continued searching for new challenges.
After five successful defenses of his WBO super middleweight title, Ramírez moved into higher weight classes. His ambition eventually took him to the cruiserweight division, where he created another important chapter in Mexican boxing.
In 2024, he defeated Arsen Goulamirian to win the WBA Super cruiserweight title. Later that year, he added the WBO championship by defeating Chris Billam-Smith.
For a fighter who had already made history at super middleweight, becoming a unified champion at cruiserweight demonstrated the longevity and adaptability of his career.
Then came Las Vegas again.

Yet one loss does little to erase a career built over more than a decade.
In August 2026, The Ring continues to rank Ramírez No. 2 among the world’s cruiserweights. (Box-Rank)
That ranking reflects an important reality: Ramírez remains a major figure in one of boxing’s most competitive divisions.
His career also illustrates something larger than sport.
From Mazatlán to Las Vegas, from construction sites to championship stages, Ramírez has become an example of how Mexican boxing continues to produce fighters capable of competing on the world’s biggest stages.
His story is not simply about titles.
It is about opportunity, reinvention and the ability to remain relevant after reaching the highest levels of the sport.
For Gilberto “Zurdo” Ramírez, the championship belts are part of the legacy.
