I think Bierdamann's 200 free is his last world record standing, hopefully Popovici gets it soon (unfortunately he had to retire today from Romanian Nationals after a promising 47.30 in the prelims cause of back pains).
David Popovici set a personal and national best of 21.83 in 50m freestyle at the Romanian National Championship, becoming the first man in history under 22, 47 and 1:43 . He'll probably be aiming for the 50-100-200m freestyle triple in LA.
