Q. How, if at all, is Serena's game different on the grass than on the hard courts?
VICTORIA AZARENKA: Well, the serve I think is more efficient, you know. It's harder to return. The groundstrokes are also faster on the grass.
But, I mean, the game she played today, if she would play on hard courts or on any other surface, it would be pretty good, you know. It was just her day, you know, and she played amazing tennis.
