The Greek says he didn’t expect success to come so fast.

Wimbledon, England— Stefanos Tsitsipas is stoked about Wimbledon, even though he was knocked off by bomb-serving John Isner on Day 7 of the Championships.

The 19-year-old Greek become the first ATP player from Greece to reach the round of 16 at a major at Wimbledon and he told the press on Monday that even though he set a goal to accomplish just that, he never truly believed it can happen so fast.

“It was a wonderful week,” Tsitsipas told reporters at a press conference. “Actually I never thought that this year—it was actually my goal. I had goals in the beginning of the year to do fourth round of a Grand Slam. I actually believed it, but I never thought it’s gonna come that fast and that quick, and it just came with all the hard work I did this year.”

Tsitsipas, who was seeded at a major for the first time at Wimbledon, had never won a main draw match at Wimbledon prior to this season. But this year he was one of the stars of week one, captivating audiences with his head-first dives and his flair for the dramatic. In the second round he rallied from a break down to defeat America’s Jared Donaldson in five sets.

In the third round he defeated a good friend, Italy’s Thomas Fabbiano.

“I actually did get a bit emotional that I was in the last 16 of a Grand Slam that I have been dreaming of winning one day, and hopefully I can win it one day. It would be an amazing feeling. But the vibes and the emotions and the conditions this year were just absolutely perfect, and despite the loss today, I can only take positives out of this Grand Slam, this very important Grand Slam that happens to be Wimbledon, one of my favorite Grand Slams. And I’m leaving from London with very nice memories.”

Tsitsipas says he will take some time off before playing a clay-court event in Hamburg in two weeks.
