Phelps appeared from behind the ASU student section’s “Curtain of Distraction,” standing between two shirtless students with 13:47 left to play.

With gold medals around his neck and a yellow swim cap on his head, and little else, Phelps stripped and danced as Oregon State’s Stephen Thompson Jr. missed two foul shots. The moment drew the loudest cheers from the crowd at Wells Fargo Arena.
