My worst memory as a fighter came against Matt Vanda in July 2008 in Hermosillo, Sonora, Mexico.
I had a very difficult time in the ring. It was very hot all week and I started getting sick the day before the weigh-in and never fully recuperated after the weigh-in. I had a fever the night before the fight, but I went through with it and the last two rounds were the most difficult time I had in the ring. I could barely walk and was just standing up because of my pride and my heart. I threw up in the ring after the fight and had a fever.
My best memory is winning the world middleweight championship. It was my dream to become a world champion. That's why I decided to become a professional fighter. Beating Sebastian Zbik in Los Angeles in June 2011 to become the middleweight champion is something that I will never forget -- and for so many reasons.
Not many people believed that I could do it and that inspired me. The select few who did believe in me encouraged me and sacrificed for me. And to win the title only a few blocks from the old Olympic where my father won his first world title, well, that made it even more special for me. My father and I will always be linked together because we won our first world championship belts in the same city.
It is a feeling that will stay with me forever. To hear the ring announcer say, "The winner and new . . . " That is something I will never forget. That is something I never want to forget. Of course, I now like hearing the ring announcer say, "The winner, and still . . . "
And that's exactly what he will say in the ring on Sept. 15 after my fight with Sergio Martinez ends.
