"I think I was putting a lot of pressure on myself, and at the end of the first set I had my chances. At that point, I was willing myself to play unbelievable tennis when just serving would have been fine. I know it's a cliche, but it's all part of the experience."
Robson is expected to move into the top 30 of the WTA rankings at the end of the tournament.
