Juan Martin del Potro: I feel glad. I played good match today. (Ivan) Dodig come with a lot of confidence. He won a tournament two weeks ago so I’m glad to beat him. Of course I want to take the opportunity to pass through to the semis.

Question: Are you finding with each win, each match; you feel a little more comfortable in your comeback?

Juan Martin del Potro: Well, winning matches helps a lot to improve the game; to keep confident. I’m trying to do the things easier. But everyone here is complicated for me. At this moment, I’m not playing for… how do you say, for a week, good tennis. I have good matches. I have bad matches, but I’m trying to improve day by day, match by match and hopefully play good tennis tomorrow.

Question: Juan Martin, you played really well in San Jose, and you played fantastic I thought last night also against Isner. Do you feel like you are getting back to one hundred percent?

Juan Martin del Potro: Yes, I working for that. I’m improving week by week. After Australia I came to Argentina with a little (unheard). But now I’m glad I improved by serve and my forehand too. And if I have confidence to play good shots with my forehand, that’s a good reason to be happy for me.

Question: You been playing a lot of tennis recently after being out for so long. Are you feeling okay physically? How’s the wrist holding up?

Juan Martin del Potro: Yes, I’m feeling well. Of course I… every match I finish tired. Because when you’re out, you are out for a long time, it’s difficult to come back. I’m working hard with my physical trainer to be healthy for all the season. And if I be healthy for this year, I will be happy. I don’t have any goals with the rankings or the tournaments… just playing healthy for the rest of the year.

Question: Can you talk a little about your doubles match today? Do you think you’ll play a lot more doubles this year?

Juan Martin del Potro: I don’t think so. (smiles) I’m not a specialist. But I really have fun playing doubles. I like to play here in the States. I always play with Mardy Fish. And maybe we play together in Europe, some clay tournaments, but the singles my best decision.

Question: Are you surprised at all by the success you had in San Jose and being in the quarterfinals here?

Juan Martin del Potro: Yes, could be a surprise being in the quarterfinals again… beat Isner… last week Hewitt. But I need time to be in good shape again. Of course winning matches helps me to build confidence very easily. But I know that the road to being a good player again is very long.

Question: You had surgery back in May at the Mayo Clinic?

Juan Martin del Potro: Yes.

Question: Did you ever feel like that injury was going to be career-threatening?

Juan Martin del Potro: When you… when I was with my wrist problem, I see everything (unheard), you know. And nobody finds the problem with my wrist. I was for four months, trying to find the problem. And nobody knows nothing about it. And I came here for to see a doctor in Rochester. And he say, ok you have two ways to do. One is the surgery, and the other one is to take a long time. But, no, you know, if you don’t make the surgery, maybe you cannot fix the problem. So I take that decision. And after surgery, you never know if my wrist will be… in same place, same feelings and everything the same. But now I’m ok. I can play so the past is over.

ATP Tour: Last two questions.

Question: This is a quick non-tennis question. I noticed that you and (Radek) Stepanik matched out there (in doubles). How did that come about? Whose idea was it?

Juan Martin del Potro: We talked in Australia to play doubles here. We have good relationship. I never play doubles, so it’s good for me, because I need to play matches and matches so. I don’t play doubles in Delray Beach to rest for Indian Wells and Miami. So maybe in the next couple of months, I’m playing with Mardy Fish.

ATP Tour: (Reporter,) last question?

Question: No. Thanks.

ATP Tour: Thank you.

Juan Martin del Potro: Bye.
