US Open report card

A+: Serena Williams

GOAT. The real number 1.

A: Victoria Azarenka

The paper number 1 gave the real number 1 a real scare. Good signs for Victoria.

A-:  Maria Sharapova

Fought hard but lost to Azarenka in the semis. However, will most probably be destroyed by Serena in the finals anyway.

B+: Roberta Vinci

Disposed of unworthy number 2 seed in impressive style; first QF appearance in her career.

B: Samantha Stosur

Did well to reach the quarters. Fought to the bitter end but lost a tight one to eventual finalist.

B-: Laura Robson

Feisty youngster took out Clijsters and Li back to back. One to look out for in the future.

C+: Angelique Kerber

Seems to only know how to play hard hitters. When facing someone who isn't one, she struggles.

C: Ana Ivanovic

First QF in 4 years; although helped by a soft draw.

C-: Kim Clijsters

Fought her heart out but lost to a better player that day in Laura Robson. No tears for the former champion as she leaves in smiles. She will be truly missed.

D: Agnieszka Radwanska

Paid the consequence of overplaying by losing to Vinci. Uninspired play and unworthy of the number 2 seed.

E: Petra Kvitova

Just when you think she's gotten the formula of being consistent, she loses a shock 4th round to Bartoli. We are still waiting for Kvitova to show her true potential. However, I'm beginning to think that the wait is futile.

F: Caroline Wozniacki

No words. No fight, no plan, no power, nothing. She just seems disinterested and distracted. A good case study for Radwanska on what happens when you overplay and get to the number 1 position when you don't deserve it.
