OEIRAS, Portugal — Roger Federer faltered in his tuneup for the French Open, losing to defending champion Albert Montanes of Spain, 6-2, 7-6 (5), yesterday in the Estoril Open semifinals.

Montanes, seeded fourth, will play for the title today against Frederico Gil, who became the first Portuguese to reach the final after he upset fifth-seeded Guillermo Garcia-Lopez of Spain, 6-2, 5-7, 6-3.

Unseeded Anastasija Sevastova of Latvia captured the women's final, downing Arantxa Parra Santonja of Spain, 6-2, 7-5, for her first career title.

Federer made 48 unforced errors, mostly on his backhand. The top-ranked Swiss was more consistent in the second set on a damp day following heavy rain, but he blew a 5-2 lead in the tiebreaker in which Montanes won the last five points.

Federer came to Estoril for the first time to get more matches on clay in preparation for his French Open title defense this month. He lost his opening match to 40th-ranked Ernests Gulbis at the Rome Masters and won only two matches in Estoril.

ITALIAN OPEN

JANKOVIC FALLS IN FINAL

Jelena Jankovic lost the Italian Open final to unseeded Maria Jose Martinez Sanchez yesterday in Rome, falling 7-6 (5), 7-5 to the Spaniard's array of touch volleys and drop shots.

The seventh-ranked Serb beat hard-hitting Venus and Serena Williams in her previous two matches, but struggled against Martinez Sanchez's clay-court shotmaking in this warmup for the French Open in two weeks.

It's the first Tier I title — and third title overall — for the 26th-ranked Martinez Sanchez.

"It was really an unbelievable tournament for me," Martinez Sanchez said. "What can I say? It's incredible."

SERBIA OPEN

ALL-AMERICAN FINAL

Sam Querrey and John Isner won semifinal matches yesterday at the Serbia Open in Belgrade, setting up the first all-American ATP clay-court final in Europe since Jim Courier defeated Andre Agassi for the 1991 French Open championship.

Querrey, seeded third, routed 18-year-old Serbian wild card Filip Krajinovic, 6-1, 6-2. Isner, seeded second, beat fourth-seeded Swiss Stanislas Wawrinka, 7-5, 7-5.

Querrey needed just 51 minutes to dispatch Krajinovic, who was playing his first ATP semifinal. Querrey will try to win his fourth ATP title and first on clay.

"I played well tonight, hope I can repeat it tomorrow," he said.

BMW OPEN

TOP SEEDS TO MEET

Top-seeded Marin Cilic of Croatia will play second-seeded Mikhail Youzhny of Russia in the final of the BMW Open in Munich.

Youzhny beat Philipp Petzschner of Germany, 7-5, 7-6 (5), to advance to his second straight BMW Open final.
