Stefanos Tsitsipas victory sets up Daniil Medvedev semi-final showdown in Rome

The two tennis titans eased through their quarter-finals on Thursday, with third seed Medvedev, who had never won a match at the Foro Italico prior to the start of the tournament, ending the run of qualifier Yannick Hanfmann with a 6-2 6-2 victory.

"I remember sitting here before the tournament and saying how good I felt in practice," the Russian told reporters in the Italian capital.

"It's always tricky because then you can lose first round against a great opponent and you're going to be like, 'Yeah, well, why did I say this? Better shut up.' That's how I felt. I'm happy I managed to transfer this onto the tennis court."

Tsitsipas had to wait until the night session to take on Borna Coric and produced a fine display to see off the 15th seed 6-3 6-4.

There was a slight blip in the second set when his initial break of serve was quickly returned by Coric, but the Greek quickly recovered.

"This is clay-court tennis, things escalated quite quickly. And there was a turning point, but accompanied by my great shotmaking, at the very important moments, I was able to retrieve that and get back and hold," Tsitsipas said. "[I played] a great service game in the very last game, serving excellently and just feeling the energy point by point."

It will be a 12th meeting between regular rivals Tsitsipas and Medvedev. Medvedev leads 7-4 but Tsitsipas has won the last two and also beat the Russian at the French Open two years ago.
