[1] Serena Williams (USA) d [3] Agnieszka Radwanska (POL) 76(3) 64
"This was definitely a much better match than, for example, in Miami,"
Radwanska said. "It was really close and I had my chances but wasn't really
taking them. She definitely played well, especially in the tie-break. And she
played much better in the end of the second set, playing aggressive and deep.
"That's what makes her No.1 in the world, playing unbelievable in the very
important moments, and just hitting some very powerful shots. I couldn't
really do anything about that against her tonight."
