Biography
About Gilberto “Zurdo” Ramírez
Gilberto “Zurdo” Ramírez is a Mexican professional boxer and former world champion in two weight divisions. The southpaw from Mazatlán, Sinaloa, established himself as one of Mexico's leading fighters during a professional career spanning super middleweight, light heavyweight and cruiserweight.
Ramírez became WBO super middleweight world champion in 2016 and compiled a lengthy unbeaten run before moving permanently into the light-heavyweight division. He suffered his first professional defeat against Dmitry Bivol in a WBA light-heavyweight world-title challenge in November 2022.
Ramírez subsequently moved to cruiserweight and defeated former world champion Arsen Goulamirian in March 2024 to capture the WBA cruiserweight championship. He then defeated WBO champion Chris Billam-Smith in November 2024, unifying the WBA and WBO titles and becoming one of the division's leading champions.
After successfully defending against Yuniel Dorticos in June 2025, Ramírez faced undefeated David Benavidez in a major unification fight at T-Mobile Arena in Las Vegas on 2 May 2026. Benavidez dropped Ramírez twice and knocked him out at 2:59 of the sixth round, ending Ramírez's unified championship reign and leaving his professional record at 48–2 with 30 knockout victories.
