LOS ANGELES: Serena Williams represents the United States' best chance to hoist the French Open trophy this year but questions loom about her fitness after she was forced to withdraw from the Italian Open last week with a knee injury.
Powerhouse Madison Keys, who fell to Stephens in the French Open semi-finals last year, won her first clay court title at the Charleston Open in April, defeating Stephens and Caroline Wozniacki in the process. The top American man, world number 10 John Isner, last week withdrew from the French Open due to a foot injury he picked up during his Miami Open final defeat by Roger Federer in March.
