A straight sets win again for Greece’s king of tennis, Stefanos Tsitsipas, beating Spain’s Pablo Carreno Busta 6-3, 6-2, 7-5 to the quarter finals on Sunday.

“My performance was good. I was very mentally there in every single game,” Tsitsipas said in a post match interview.

“Whether I was serving or not, I was very concentrated in the procedure, in the process.”

The World No.5 was on point from the get go, executing some powerful backhands and returning consistent depth on his forehand return, allowing him to bolster ahead 4-1. Towards the end of the first set, Tsitsipas fended off two break points at 4-2 and closed the with an ace.

Tsitsipas continued with the same force in the second set, managing to lead 4-0. It seemed he had tired the Spaniard out a little, as his opponent won just 30 per cent of points on Tsistipas’ second serve.

Carreno Busta came back swinging in the third not wanting to give up the quarter finals spot so easily and took the lead 3-0 with a strong forehand. Unfortunately for him, Tsitsipas had other plans creeping up to meet him at 3-4 and eventually took out the Spaniard, claiming four of the final five games ending on 7-5.

The young Greek gave some insight on his mindset for the match that unfolded on Court Philippe-Chatrier after the duel.

“I think I’ve played some of my best tennis when I don’t think much on the court, when everything is being done automatically, on autopilot,” Tsitsipas said.

“I felt also my performance was at the top [against Carreno Busta]. So, yes, less thinking, more action.”

Tsitsipas also went on to give some kudos to Carreno Busta, aware that he drove a hard game against him.

“I think every single match that I had against him was a learning experience. I had high expectations for him, and that’s a good thing, going into the match having high expectations [for] your opponent,” he said.

“I think I also had a great start, very good start, where I didn’t let him attack a lot. I actually gave him not that much space to get going.”

Tsitsipas is set to meet Russia’s Daniil Medvedev with hopes of making it through to the semi finals and knows he has a challenging opponent ahead.

“He does serve extremely well, I have to say. He has improved over the years with his serve. This is going to be something that I will have to face,” Tsitsipas said.

“Of course, myself playing well, I feel like I don’t have to think about who I’m facing or not. I just have to play my game, let the rest be witnessed.”
