Stefanos Tsitsipas is moving on at the Mexican Open.
In just 57 minutes, Greece's tennis star just defeated American John Robert Isner 6-3, 6-2.
“I think I had good return games today and that was very important. You don't want to get into tie-breaks with this guy, it can get really dangerous," he said in his post match interview.
"Today I just managed to stay composed and concentrated on all moments. I had opportunities, I won actually most of my break point opportunities… which was important. It gave me so much confidence throughout the whole match.”
He will now face Canadian Felix Auger-Aliassime.
