Tsitsipas set up match point with a scorching crosscourt victor before completing the victory in two hours 17 minutes.
Tsitsipas, the 19-year-old rising star, took two hours and 17 minutes to beat Djokovic in his first-ever match against the ninth-seeded Serbian, a victor of four Canadian Open titles and a 13-time Grand Slam champion.
With this, he reached his maiden ATP World Tour Masters 1000 quarter-final. "But I just played not that great, especially from the baseline".

But Tsitsipas broke in his first return game of the third set and never looked back.
Tsitsipas would not be brushed aside, though, and a huge shot down the line sealed an early break in the third, before fighting back in a sublime hold that prompted Djokovic to smash his racket.
