Bence Biczo

Biczo will be making his Olympic debut, but the young Hungarian has really come on the past two years to become a legitimate medal contender. He had his first taste of international success at the 2010 European Youth Championships, where he won the 200-meter butterfly with a youth-record time of 1:55.82 - the sixth best result of that year overall. His greatest achievement came one year later when he beat defending champion and Olympic silver medalist Laszlo Cseh in the 200 fly at the Hungarian championships. Biczo, just 19 years old, is ranked second in the world in that event and figures to be a main challenger for Michael Phelps in London.
