It was a far closer match than Novak Djokovic anticipated but the Serbian was able to get it done in three 6-2 3-6 7-6(4).
They played in the Astana Open fairly recently with Djokovic winning in two simple sets. This match opened in a very similar fashion as Djokovic was once again in full control smashing the Greek 6-2. The Serbian was pretty much near perfect hitting 8 winners in total with zero unforced errors.
The Greek responded in the second set playing much better than before. He took a break midway through the opening set as Djokovic was unable to exert any pressure with his returns and did not play as precisely as he did in the first set.
Tsitsipas finished off the set with another break 6-3. The final one was a great one with both players holding their serve. Tsitsipas was forced to save double break points in two separate games but managed to do so both times.
In the tiebreak, Tsitsipas jumped out to a 4-3 lead but then dropped both of his serve with a crucial point at 5-4 won by Djokovic. The Serbian then closed it out 7-4.
