Forty ``social distance ambassadors'' will monitor the U.S. Open grounds to make sure players and others are avoiding close contact and wearing face coverings -- the U.S. Tennis Association bought 500,000 masks to distribute -- as part of efforts to avoid a coronavirus outbreak during the fan-free Grand Slam tournament.
The USTA announced Tuesday that one person, who is not a player, turned up positive for COVID-19 out of 1,400 tests administered in the controlled environment set up for the U.S. Open and another tennis tournament preceding it at the same site in New York.
