Sorry, I can`t deal with this expression. It really depends on your opponent and whether he can challenge you to do something very special. She has in nearly every match some spectacular shots.
The second set against Wickmayer was great, but I still admire most her fabulous shotmaking and amazing points in these high-speed rallies in her match against Azarenka at Stuttgart.
She would have won against Azarenka in Stuttgart without these 16 double faults and her very low first serve percentage (i think it was about only 40 %).
