The 20-year-old, who was making his third appearance in Melbourne, dropped just one set en route to his second major quarter-final and believes the experience can help him develop further.
“Of course, it’s a positive tournament,” Sinner said in his post-match press conference. “I think that what I have to improve is the tennis in general. I have to serve better, I have to do everything more, especially when you play against the top guys.
“My goal is to play many matches like this, important matches against the best guys in the world, and then we see and then I grow. I think it was good. I played matches, and I had [a good] experience. Let’s see next year what I do here.”
The Italian won four tour-level titles in a standout 2021 season and was aiming for his second win against the fourth-seeded Greek. However, he was unable to match the intensity of Tsitsipas, praising his level.
“I think he played better than me today,” Sinner added. “He served better. He moved the ball better than me. He was moving better than me. It’s tough to play against him when he plays like that.
“I couldn’t generate the power that I would have wanted. I was trying to move him, but I was maybe a little bit too far back because he played incredible today.”
Sinner will next compete in Rotterdam, an ATP 500 indoor-hard event, at the start of February.
