TORONTO—Stefanos Tsitsipas has been looking virtually unstoppable in recent weeks. On Thursday, the 19-year-old Greek stunned Novak Djokovic at the Rogers Cup to reach his first ATP Masters 1000 quarterfinals. 

Tsitsipas' reaction to the 6-3, 6-7 (5), 6-3 win said it all. 

He earned the victory over the recent Wimbledon champion with shots like this:

And big backhands at key moments like this:

Even Djokovic was smiling and shaking his head by the end of the match, in apparent respect and awe of the teen's performance. The two put on quite a show: 

"Obviously he's a favorite," Tsitsipas said before the match. "So I'll just play my game, be patient. There are going to be few opportunities in the match. I just need to use my chances as correct as possible and not hurry at all and just enjoy my time out playing in the center court, in such a beautiful center court here in Toronto."

He certainly looked to be enjoying himself. It was Tsitsipas' second Top-10 win of the week as he ousted Dominic Thiem on Wednesday in straight sets.

The world No. 27 is on quite the roll coming in from Washington where he made his fourth career ATP semifinals. In the U.S. capital, he got a big win over world No. 11 David Goffin before falling to eventual champion Alexander Zverev, who he plays next in Toronto. 

Tsitsipas is winning over fans left and right with his whopping one-handed backhand, flashy outfits and humble personality. His Greek fans are certainly grateful to have a new role model.

Tsitsipas is guaranteed to rise to a career-high ranking no matter what happens in his next match.

"At at the moment I'm just concentrating getting high in the rankings. Even one spot for me is a big thing," he said. "So I'm just trying to concentrate and getting as many points as I can, staying concentrated on my work."
