Ernesto Peña

At the 2004 Summer Olympics in Athens, Pena qualified for the Cuban team in the men's 96 kg class by receiving a berth from the first Olympic Qualification Tournament in Novi Sad, Serbia and Montenegro. In the preliminary pool, Pena upset U.S. wrestler and 2000 Olympic bronze medalist Garrett Lowney on his opening bout, and then threw out Hungary's Lajos Virág into the ring for a spot in the quarterfinals. Pena suffered his major defeat from Turkey's Mehmet Özal in the quarterfinal match on the next day's session, but offered a chance to redeem himself in the ring by ousting Kyrgyzstan's Gennady Chkhaidze for a fifth place finish. When Iran's Masoud Hashemzadeh was disqualified for a bronze medal protest, Pena uplifted his position to fourth, and nearly missed out the podium.

Pena emerged himself into the global scene at the 2001 World Wrestling Championships in Patras, Greece, where he picked up a silver medal on his first ever final match against Russia's Aleksandr Bezruchkin. He continued to reach the summit of the world rankings, by finishing fourth at the 2002 World Wrestling Championships in Moscow, Russia, and by overpowering U.S. wrestler Justin Ruiz to snatch the heavyweight Greco-Roman wrestling title at the 2003 Pan American Games in Santo Domingo, Dominican Republic.
