Career Highlights: At only 18 years old, Stjepanovic clocked the world's fastest time for the year in the 200 meter butterfly at 1:56.18 at the British Gas Swimming Championships in March. That time has subsequently been beaten by other swimmers, but it was more than one-half second faster than the automatic qualification mark for the Olympics. Despite having lived his entire life in the United Arab Emirates, Stjepanovic, who won gold in the 100 meter freestyle and 100 fly at the 2011 European Junior Swimming Championships, will compete for Serbia, where both of his parents are from. Stjepanovic’s training was interrupted for more than a week in early May when he was diagnosed with gastritis, a condition that effects the lining of the stomach. He viewed the unscheduled break as a positive, however, as it gave him time to rest a sore back.
