Stefanos Tsitsipas battled back from a 1-3 deficit, in the third set, to defeat Karen Khachanov 4-6, 6-3, 7-5 in the quarterfinals of the ABN AMRO World Tennis Tournament.
Second seed Tsitsipas improved his perfect record to 3-0 against Khachanov with the two hours and 42 minute victory.
Tsitsipas hit a total of 46 winners, including 28 off his forehand win.
The 22-year-old will return to the court later on Friday to partner his brother, Petros Tsitsipas, in their doubles quarter-final against Henri Kontinen and Edouard Roger-Vasselin.
On Tuesday, Tsitsipas had said that for each tour-level doubles match he wins with his brother, he will donate 3,000 euros to Mazi gia to Paidi (Together For Children), whose mission is, “to provide immediate and effective support to children, families, and individuals with disabilities who are in need”.
“That’s for a great cause and also winning, it’s a great thing. The more we win, I really don’t have a problem donating,” he added.
“I donate anyway, but I think that’s an extra reason to push ourselves to want to do better.”
Khachanov is now 7-3 on the 2021 season, having advanced last month to the Great Ocean Road Open semi-finals (l. to Sinner) and the Australian Open third round.
It has been a good start to the year for the Greek star.
At the Australian Open, he overcame a two-set deficit to beat Rafael Nadal to seal his place in the final four. Tsitsipas became only the second man, after Fabio Fognini at the US Open, to beat Nadal at a Grand Slam after being two sets down.
