"It's because I did a lot of things well. I played more aggressively than the previous days. I went to the net more often, and I hit a lot of winners," added the 12-time French Open champion, who needed only one hour and 35 minutes to see off his opponent.
"I think it was played out at a few points really. These are a few points that rocked the game. I did not know how to seize the opportunities that I had mainly in the first but also in the second set. This is what made the difference today," Burel commented on her performance in brief.
"We had a good start in each set, but in the second set, when one of the opponents left the court with an injury, I felt our players relaxed a bit mentally. Then I asked for a time out to prevent our team from losing ground. There is no doubt that we played well in the last two sets," said Tianjin head coach Wang Baoquan.
