Michael Phelps has gotten through his toughest night of the U.S. Olympic swimming trials.
After beating Ryan Lochte in the 200-meter individual medley Friday, Phelps returned to the pool 30 minutes later to post the sixth-fastest time in the semifinals of the 100 butterfly.
That was good enough to send Phelps to the final Saturday night, where he'll try to lock up a third individual event for the Rio Games.
Phelps also qualified in the 200 fly.
