The oppressive heat and humidity at the U.S. Open continued to take their toll as Jack Sock, an American seeded 28th, collapsed to the court and retired against Ruben Bemelmans.

After hitting a serve at 1-2 in the fourth set Thursday, Sock clutched his left leg. He was unable to move and seconds later fell backward toward the court and had to be assisted by an ATP trainer.
