Juan Martin del Potro, on his wrist injury after a 6-4, 6-4, 3-6, 6-2 opening win over Michael Russell: "Of course, I don't feel hundred percent, but I am feeling better than yesterday, and I hope be better for tomorrow, for Wednesday, in my next match.
"After two hours match the pain came and I feel a little bit, but I can play. Of course, if I be here, I want to win matches."
