Stefanos Tsitsipas battles into the Rotterdam semifinals

Stefanos Tsitsipas has done it to reach the Rotterdam semifinals.

Greece’s star secured a 4-6, 6-3, 7-5 victory over Russia’s Karen Khachanov.

"He was playing great tennis and I wasn't sure if I would be able to compete," Tsitsipas said in his post match interview.

"We had great rallies and the quality of tennis was excellent."

"You need to stay as calm as possible in three-setters. I have won a lot in the past and with experience, it gives me an idea of how to play in these tight moments."

He will now face fourth-seeded Russian Andrey Rublev in Saturday’s semifinals
