SYDNEY: Greece badly missed elbow-injury victim Stefanos Tsitsipas in the singles when it was beaten by Poland on the opening day of the 16-team ATP Cup tournament on Saturday.

World No. 4  Tsitsipas was a late withdrawal from 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.
