Ivan “Iron Boy Calderon, a two-division world champion and former Top 10 Pound4Pound fighter, has announced his retirement after an 11-year career.
Calderon started his career in 2001 at strawweight/minimumweight (105 pounds) and won his first world title two years later, defeating Eduardo Ray Marquez. He would go on to make 11 dominant defenses before moving up to the light flyweight division in 2007. There, Calderon won the WBO strap in tough fight against Hugo Fidel Cazares and made six defenses before suffering his first defeat, a TKO loss to Giovanni Segura, in 2010. Calderon would also suffer a knockout defeat to Segura in a 2011 return bout and lost his most recent fight, a fifth round TKO, to Moises Fuentes on October 6.
Lacking knockout power, Calderon relied on defense and technical skill to outpoint opponents and was for most of his career considered one of the best pure boxers in the sport.
In a retirement ceremony in his native Puerto Rico, Calderon revealed future health was the deciding factor in choosing to hang up the gloves.
This was difficult because (boxing is) something I love, but I want to say that I’m doing this not because I’m old or tired. I’m doing this because I want to work with the kids and youth, bringing them my knowledge and tips. I want to be an example for all my fellow boxers that when it is time (to retire) it is time, no matter if we are rich or poor. The health is what matters. I want to thank all (the fans).
Ivan Calderon leaves the ring with a final record of 35-3-1, with 6 KOs.
