In the morning prelims Jones rewrote the American record for the men's 50m freestyle with a new time of 21.59. Later that day, Phelps went on to beat his own world record in men's 200m individual medley (1:54.98), clocking a new low of 1:54.80. First seed Ryan Lochte finished behind Phelps at 1:55.22.
