A+: Petra Kvitova
I don't think anyone on tour could have survive Kvitova in the final match. Just flawless hitting from the Czech.
A: Venus Williams
Strange to give such a high grade to a 3rd round loser, but she was the closest to defeating Kvitova. Venus went toe to toe with the champion and was 2 points away from victory.
A-: Eugenie Bouchard
Young star was humbled by Kvitova in the finals, but has a lot to be proud of for her first slam final appearance.
B+: Simona Halep
Seems like the only dependable player on tour. Unfortunate injury in her semi-final, but would have been destroyed by Kvitova anyway.
B: Lucie Safarova
Finally advances to her first slam semi-finals after years on tour. Let's see if she can build on this momentum.
B-: Barbora Zahlavova Strycova
Drop shot queen of the tournament, scoring upset wins over Wozniacki and Li Na. Also showing signs of maturity as she's not as animated as before.
C+: Sabine Lisicki
Didn't go all the way to the final this year, but still manages to reach the quarter-finals despite an absolute horrendous year. Now see her fade back into obscurity.
C: Tereza Smitkova
Who? Another Czech who took most of an open draw to reach the last 16. One to watch in the future.
C-: Maria Sharapova
Didn't handle the pressure of being the favourite well, faltered badly against Kerber. Grass is quickly becoming her worst surface.
D: Agnieszka Radwanska
Expected her to make things difficult for Makarova, but just went down meekly. Looks like she'll never win a major.
E: Li Na
Her split with Carlos Rodriguez definitely was a contributing factor, but her weakness was fully exploited by Barbora. At her age, it remains to be seen if she has the motivation to bounce back.
F: Serena Williams
Maybe F is too harsh for Serena, but she came into the tournament all serious and eager to prove the detractors wrong. However, she was just missing for the past 2 slams. Will Serena get back on her feet? Or is there something wrong with her health given that she withdrew under mystifying circumstances?
