None other than Nadia Comaneci. She was beaten out for third place by.01 seconds by a diving Jenna Prandini in the 200-meter final.

It wouldn't have mattered if Molly Huddle celebrated this one early.
But U.S. trials don't guarantee anything, and on Sunday, a few more potential medal contenders - including 400-meter hurdlers Johnny Dutch and Bershawn Jackson - also saw some dreams end early.
