Geneva: Top-seeded Sam Querrey lost his opening match at the rain-hit Geneva Open on Thursday, falling to Guido Pella of Argentina 7-5, 6-7, 7-6.

It was the 13th-ranked American’s third straight quick exit from a clay-court event before the French Open begins on Sunday. Querrey also lost to Pella last month in Houston.

Querrey broke the left-handed Pella’s serve only once as his record fell to 10-10 this year.

Meanwhile, South Korea’s promising tennis star Chung Hyeon was forced to withdraw from the French Open due to an ankle injury that has dogged him throughout the clay season.

Chung, 22, was expected to play a warm-up tournament in French city Lyon prior to French Open, but withdrew from it due to the injury, reports Xinhua news agency.

“Unfortunately I had to withdraw from Lyon yesterday and now Roland Garros,” Chung tweeted late on Wednesday. “I have been struggling with an ankle injury during the entire clay season,” he added.
