Greece badly missed Stefanos Tsitsipas in the singles when it was beaten by Poland on the opening day of the 16-team ATP Cup tournament on Saturday. The fourth-ranked Tsitsipas had to withdraw with an elbow problem ahead of his match with ninth-ranked Hubert Hurkacz, who went on to beat replacement Aristotelis Thanos 6-1, 6-2 to give Poland an unassailable 2-0 lead after Kamil Majchrzak had defeated Michail Pervolarakis 6-1, 6-4 earlier. Greece then gained some consolation when Tsitsipas combined with Pervolarakis in the doubles to overcome Szymon Walkow and Jan Zielinski 6-4, 5-7, 10-8.

Stefanos Tsitsipas heard boos from the crowd for yet another long trip off court at the U.S. Open after dropping a set during his second-round victory over Adrian Mannarino. Unbothered by that reaction Wednesday night, or the criticism he received from Andy Murray after taking breaks while beating him two days earlier, Tsitsipas pointed out that he's doing nothing that violates any regulation. The Grand Slam rule book just says players should take a “reasonable” amount of time, but does not provide an exact number of minutes that would be acceptable.

Unlike the nine players who met with the media in that spot a day earlier, Murray chose to keep his mask on.
