American Sloane Stephens has withdrawn from the U.S. Open because of a right foot injury.
The announcement Friday means that Olympic gold medalist Monica Puig becomes the 32nd and final seed, as Stephens had been seeded 24th. Had Puig remained unseeded, she could have met one of the top players in the first or second round.
The 23-year-old Stephens was a 2013 quarterfinalist at Flushing Meadows and reached the semifinals at the Australian Open that year. While she had more success earlier in her career in the Grand Slams than in other tour events, that pattern had reversed in the last couple of years.
Stephens hadn't played since losing in the first round at the Olympics.
