PARIS (Reuters) - Hopes of a homegrown winner at this year's French Open disappeared in the Parisian gloom on Sunday when Jo-Wilfried Tsonga retired injured from his fourth-round clash against Russian Mikhail Youzhny.
Tsonga, the eighth seed, received treatment to his leg when trailing 5-2 in the opening set and called it a day when Youzhny, the 11th seed, won the following game.
Tsonga spoke to the chair umpire, flung his racket onto his chair and offered Youzhny his hand.
The former Australian Open finalist was the only Frenchman left in the draw at Roland Garros.
Youzhny will next face either Briton Andy Murray, the fourth seed, or Czech 15th seed Tomas Berdych.
"It looks like it is a lesion on a stomach muscle," Tsonga told reporters.
"I will have an MRI tomorrow to see exactly what it is."
Tsonga felt pain even before entering the court and took no risks during training to preserve his chances against Youzhny.
"There is always a risk to aggravate when you play with some pain," he said.
On another grey day in Paris, Tsonga hoped rain would save him.
"I told myself that if it could rain, it would maybe be better," he said.
