The match turned bizarre in the middle of the second set. First, Djokovic, who appeared to be in some physical distress, got into an argument with his team in the players’ box over some missing pills. Then Millman asked for, and received, an unscheduled break in order to change his clothes, which were soaked in sweat on another hot night in the tournament.
Djokovic received a bottle of tablets (and some nasal spray) during Millman’s break to change, which lasted more than six minutes.
None of it stopped Djokovic from reaching the semifinals, where he will play Kei Nishikori. Djokovic has advanced to the semifinals in his last 11 U.S. Open appearances. He did not play last year’s tournament because of an elbow injury.
Djokovic has won 14 of 16 matches against Nishikori, including in the Wimbledon quarterfinals in July. But one of the losses came in the U.S. Open semifinals in 2014.
