He said: “Surprised? Not really.
“I have been playing good tennis a long time on practices. I just couldn’t, didn’t have the kind of first serve. I was missing. I had big minus in the serve.
“I improved a lot my serve lately. I think that’s why I’m in the semis now.
“In general, in the game, from the baseline I’m physically as well, feeling really good, I’m playing good, feeling the ball really well. Again, if I will manage this kind of serving well, I can keep playing good.”
