Aaron Piersol beat Micheal Phelps?

umm i never heard any news about swimming from the news ever unless it was from the olympics and i log in yahoo and see on the news section soem guy Aaron Piersol beat Micheal Phelps at a 100 meter race? did they make this news because they are ashamed that a "pothead" won more gold medals than the other swimmers and want to kick it under the map by saying hes not AS good as people made him look? am i being a bit paranoied or something?
