New York City completed its first day without any Coronavirus casualties this week though the virus is spiking in Florida, Texas and elsewhere in America.
Thiem, who edged Matteo Berrettini, 6-7, 6-4, 10-8, to win the bett1 Aces exhibition on grass in Berlin, said the US Open is on "very shaky legs."
However, the Australian Open finalist also said if the Open proceeds as planned he believes it will be safe for players.
The US Open plans to play without fans or media and create a "safety bubble" in an effort to reduce the risk of COVID-19 spread.
"I believe the decision is not in our hands, but in those of the US Tennis Federation, the US government and the Mayor of New York," said Thiem. "The whole thing is on very shaky legs. But I also believe that if it is played, it will be safe for everyone. We'll definitely be in a huge bubble."
