PARIS - Marin Cilic became the first seeded player to be eliminated from the French Open, losing to Ruben Ramirez Hidalgo, 7-6 (5), 6-4, 6-4 Sunday in the first round.
The 19th-seeded Cilic of Croatia, who reached the fourth round at the Australian Open, is a former top-10 player. But he had 67 unforced errors in the match and was broken five times.
For Ramirez Hidalgo, it was only his fourth win in 15 Grand Slam tournaments. Besides reaching the fourth round at the 2006 French Open, the Spaniard lost in the first round in each of his other 13 appearances at the four biggest tournaments on the tennis circuit.
"It's my greatest victory this season, that's for sure," the 33-year-old Ramirez Hidalgo said. "I would not say this is the beginning of a new career, because I'm too old for this, but it's a kind of relief."
Seventh-seeded David Ferrer had no such problems, advancing to the second round by defeating Jarkko Niemine, 6-3, 6-3, 6-1.
No. 14 Stanislas Wawrinka, No. 17 Jo-Wilfried Tsonga, No. 30 Guillermo Garcia-Lopez and No. 31 Sergiy Stakhovsky also advanced.
"I expected, like every year, the first match not to be too easy," said Wawrinka, who beat Augustin Gensse, 4-6, 6-3, 6-4, 6-2.
On the women's side, Sam Stosur opened her bid to return to the French Open final by beating Iveta Benesova, 6-2, 6-3 in the first round.
Stosur next plays Simona Halep, who became the first player to reach the second round by beating Alla Kudryavtseva, 6-2, 6-1.
The first seeded women's player to lose was Shahar Peer. The 19th-seeded Israeli lost to Maria Jose Martinez Sanchez, 7-6 (4), 6-1.
No. 10 Jelena Jankovic, No. 17 Julia Goerges, and No. 32 Tsvetana Pironkova advanced.
