One hour and 47 minutes needed Rafa to defeat Stanislas Wawrinka in straight sets: 7-6, 6-1.

About the match, Rafa said: "It was very tough. I think I played a great set. But the court is fast. His serve was huge. He came to the court with that determination to hit every ball by taking the ball earlier, hit the ball very quick and go for the big shots in every moment. So it was very difficult to stop him.

"The positive thing [was that] when he was playing well, I was playing well too. I was able to resist. If I was not playing well, I was going to lose that set. After that, I was able to maintain the level."

 In Shanghai semifinal Rafa will play against Juan Martin del Potro of Argentina. On head to head, Rafa leads del Potro: 8-3. Their last match was this year in Indian Wells final where Rafa won in 3 sets: 4-6, 6-3, 6-4.
