Defending champion Serena Williams is the top seed and the hot favorite to win the tournament in Madrid.
The draw is literally star-studded with all top players, but Azarenka (ankle injured), competing for the title.
The most interesting match of the first round is definitely Radwanska vs. Bouchard.
These are the possible quarters
Serena Williams – Kvitova
Halep – Jankovic
Kerber – Radwanska
Na Li – Sharapova
