Former US Open champion Stan Wawrinka has become the latest player to miss the New York Grand Slam, announcing his decision on Friday.
Wawrinka cited “the health situation in New York” as his main concern.
The 35-year-old said he will focus on Roland Garros and the French Open later next month.
Wawrinka won that major in 2015.
“There is the health situation which is particular in New York. I did not want to go the US under these conditions,” the world number 17, told RTS in Switzerland.
Players at the US Open will be subject to tight health controls.
“The sequence of tournaments which follows after the US Open will be tough,” Wawrinka said.
“And there are all the uncertainties related to the quarantine issue. There are still many questions and doubts about the holding of the US Open.”
