His post-match interview after the QF:
He says he was feeling dizzy in the 3rd set, he thought he was going to faint. He was always playing the night match this week and couldn't get to sleep then, he was not feeling well. Add to that the pressure, the fact that he was wasting too much energy in each round, and Stéphane also played a really good match. The 1st set from him was really impressive, Jim didn't even have the impression to play that badly.
The journalist tells him he was looking horribly tense, he answers he never felt well on the court this week. But at least he fought to the very end. He insists it's been a great experience for him to have to play matches with so much stress and no good sensations on the court at all. Because that's what the best players manage to do - win matches even when they're not playing well.
And he says at the end it was important to him to play there because he likes the organization, he gave his very best, it didn't work, but things can change so fast in tennis, maybe he'll win St-Petersburg next week.
