HONG KONG -- Russian Marat Safin and Australian Mark Philippoussis of Australia were upset in second-round matches Thursday at the $400,000 Salem Open.

Swede Magnus Larsson upset second-seeded Safin 6-2, 3-6, 6-4. German Rainer Schuettler ousted No. 5 Philippoussis 7-6 (5), 4-6, 6-3.

Top-seeded Spaniard Juan Carlos Ferrero beat American Cecil Mamiit 4-6, 7-5, 7-6 (3).

Larsson, ranked in the top 10 in 1995 but now languishing at 111, held his nerve in the deciding set. He saved two break points while serving for the match at 5-4. But he was aided by a fortunate call when a ball hit wide of the sideline was called in by the linesman.

"I was a bit lucky today," said the 31-year-old Swede, who broke Safin just once, in the seventh game, to take the advantage in the deciding set.

A furious Safin blamed that line call for his defeat.

"I needed a good result here to help my chances of making it to the Masters Cup in November, said the 21-year-old Russian, who won his only title this year two weeks ago in Uzbekistan. "This loss makes it more difficult."

In other second-round matches, third-seeded Sebastien Grosjean of France beat Nicolas Massu of Chile 7-6 (2), 3-6, 6-4, and Andre Sa of Brazil took Michel Kratochvil of Switzerland 7-5, 6-4.

Also, No. 6 Jonas Bjorkman of Sweden defeated Wayne Arthurs of Australia 6-2, 6-4; Andrew Ilie of Australia led No. 7 Michael Chang 6-3, 4-1 before the American bailed out because of injury, and No. 8 Marcelo Rios of Chile overcame Kenneth Carlsen of Denmark 7-5, 6-3.

Philippoussis, returning to action after a six-month layoff following surgery on his left knee, said a lack of match practice had taken its toll.

"It's all just a matter of match practice. I made a lot of unforced errors and felt a little stiff out there today," said Philippoussis, who looked more his old self in Wednesday's second round when he fired 20 aces past Israel's Harel Levy.

"But the most important thing is that my knee held up. I'm happy that it is 100 percent."
