Ian Clark (Malvern, Pa.) finished seventh with a time of 2:02.27.

“The swim today felt good but I was bummed that I didn’t hit the mark I hit yesterday,” Clary said. “I was absolutely ecstatic with my swim last night. I wish I would have been a little closer to Thiago to see where he was in the race.”
