Argentina's Juan Monaco has been eliminated from the Swiss Open after a narrow 5-7, 6-4, 7-6 (9-7) loss Friday in the quarterfinals to Russian Mikhail Youzhny.

In a two-hour, 34-minute match that was tightly contested throughout and filled with service breaks, the fifth-seeded Youzhny won despite winning just 39 percent of his second-serve points.

Monaco, the No. 3 seed, stepped up the aggressiveness on his first serve late in the match, striking five of his seven aces in the third set, but was unable to win the big points in the tiebreaker.

Each player broke his opponent's serve a whopping six times during the contest, played on clay in the mountain ski resort of Gstaad.

Next up for Youzhny in Saturday's semifinals will be Romanian Victor Hanescu, who defeated Germany's Daniel Brands 6-3, 6-4. Brands was unable to keep the momentum rolling a day after stunning top-seeded Roger Federer in straight sets.

Friday's final two quarterfinal matches pit Dutchman Robin Haase against Spain's Marcel Granollers and second-seeded Swiss Stanislas Wawrinka against Spain's Feliciano Lopez. EFE
