Career Highlights: Diaz has become the cream of the crop among American amateur featherweights, winning the 2010 and 2011 national championships as well as the U.S. Olympic trials last summer. That victory sent him to Azerbaijan for the world championships, where he earned a spot in London thanks to an impressive showing for a boxer with limited international experience. Diaz opened with a second-round stoppage victory, defeated 2004 Olympic silver medalist Worapoj Petchkoom of Thailand in the next round and clinched his Olympic berth by beating Mexico’s Oscar Valdez Fierro - a 2008 Olympian and 2009 world bronze medalist. Diaz lost a 19-10 decision in the quarterfinals, but that came against eventual champion Lazaro Alvarez Estrada of Cuba. Diaz burst onto the scene in July 2010 with his victory at nationals, where he had two stoppages and won a 12-0 decision in the quarterfinals. He defended his championship with a victory over 2010 junior national champion Joet Gonzales in the 2011 final. At the U.S. trials, Diaz didn’t lose in a double-elimination format and twice defeated 2010 Police Athletic League national champion O’Shanique Foster, including in the final. The Southern California native is coached by his father, a former teamster who had no previous experience. Diaz joined fellow Olympian Rau’shee Warren with the Los Angeles Matadors of the World Series of Boxing, going 1-1 in February 2011. He further built his resume by joining the U.S. national team in overseas bouts against England and Italy in November 2010. Diaz was the 2009 junior Olympic national champion and the 2007 national Silver Gloves champion.
