ASTANA, Kazakhstan -- Novak Djokovic delivered a near-flawless performance to ease into the second round of the Astana Open with a 6-1, 6-1 win over Cristian Garin on Wednesday as he goes for a third straight tournament title.
Djokovic dropped just six points on his serve and won the last five games to seal the win in just 62 minutes.
Djokovic is coming off a victory in Tel Aviv last week and -- aside from a match at the Laver Cup -- the Wimbledon champion hasn't lost since the French Open quarterfinals.
"From the start to the end, (it was) a great performance," Djokovic said. "Playing in a new tournament, different conditions, the first match is never easy. Obviously you are looking to see how you are going to adapt, but I did it perfectly, really, played as well as I can."
Djokovic will next play Botic van de Zandschulp.
Top-ranked Carlos Alcaraz lost in the opening round on Tuesday in his first match since winning the U.S. Open title to capture the No. 1 spot.
Stefanos Tsitsipas reached the quarterfinals by beating 19-year-old Luca Nardi of Italy 7-6 (2), 7-6 (3). Nardi was playing just his fifth tour-level main-draw match and impressed the third-seeded Greek, who didn't earn a single break point.
"He's a player that can play very well in the future," Tsitsipas said. "There weren't any holes. I believe today he was able to sustain that level from the beginning to end, and that was extremely impressive."
