Q. That was a tougher challenge than you might have been expecting for a first round?
JUAN MARTIN DEL POTRO: Yeah, of course. I didn't expect this kind of matches against him. I didn't know too much before the match how he's playing tennis.
But he serve well. His forehand is good. I start the match really, really slow, and then was difficult to come back and play my game.
But in the end, I serve well. I hit some good forehands. That's help me to improve a little bit my game.
Q. A question about your racquet. Are you using the same racquet that you used in 2009 when you won the US Open?
JUAN MARTIN DEL POTRO: Yes.
Q. Were you supposed to get new racquets before this tournament that didn't come?
JUAN MARTIN DEL POTRO: No, no. I made a test. I try a few racquets before Australian Open, but I didn't feel the confidence to change before a Grand Slam. It's not easy find the good time to change racquet. Every tournament are important for us.
But I think I'm getting closer to change racquets, and that's important for me.
