World number four Tsitsipas was a late withdrawal from his match with ninth-ranked Hubert Hurkacz, who went on to beat substitute Aristotelis Thanos 6-1, 6-2 to give Poland a secure 2-0 lead after Kamil Majchrzak had defeated Michail Pervolarakis 6-1, 6-4 earlier.
Tsitsipas watched from the team bench, as the 1,076th-ranked Thanos was outclassed by Hurkacz.
The world No.4 was ready to face world No.9 Hubert Hurkacz in a must-win match after Greece’s Michail Pervolarakis lost 6-1 6-4 to Poland’s Kamil Majchrzak in Sydney on Saturday night.
Stefanos about the withdrawal of the singles: “I’m really sorry I couldn’t play I’m not at 100% yet it has kept me behind a little. I really wanted to play, but I think it was the right thing to do. Recovery is the most important thing now.”
“I’m not playing as an individual, and I would have loved to go on court and play the best tennis, but I decided to take it a bit easier playing the doubles. I feel great about everything, my doctor did a great job”.
Poland wins 2-1 over Greece and will face Georgia on Monday.
