Gabriela Sabatini defeated Martina Navratilova, 2-6, 6-2, 6-4, Sunday in Tokyo, winning the Pan Pacific Open.

Sabatini, seeded fifth, overcame erratic serving in the first set to overpower her more accurate opponent.

"It's a wonderful feeling," said Sabatini, who defeated top-ranked Steffi Graf in the quarterfinals and fourth-seeded Mary Joe Fernandez in the semfinals. "I've been playing well here all week."

Third-seeded Navratilova, coming back from a three-month absence after surgery on both knees, breezed through the first five games as Sabatini struggled to adjust her serve on the artificial surface.

But Sabatini aced Navratilova on her first serve of the second set, and won the next three games.

Though Navratilova, 34, broke Sabatini's serve in the first game of the third set, she seemed to run out of steam three games later, allowing her service to be broken in the sixth and eighth games.

Navratilova had won all but three of her past matches against Sabatini, who is ranked fourth in the world. Sabatini won $70,000.

"I'm better than I was before the operation," Navratilova said after Saturday's semifinals, when she defeated Laura Gildemeister of Peru, 6-2, 7-6 (7-5) and Sabatini stopped Fernandez 6-3, 6-4. "There's no problem with my knees. I'm just not used to my renewed ability to move around the court quicker. I'm much happier playing because I don't have to worry about my knees and can concentrate on the match."

Navratilova remains five short of Chris Evert's record 157 career singles titles.

Davis Cup:

Sweden, which made the Davis Cup final for seven straight years in the 1980s, was eliminated in the first round when Yugoslavia's Goran Ivanisevic and Goran Prpic beat Stefan Edberg and Peter Lundgren in doubles, 6-4, 6-4, 6-4, in Zagreb. That gave host Yugoslavia an unbeatable 3-0 lead in the best-of-five competition.

The Yugoslavs swept Friday's singles, with Ivanisevic beating Jonas Svensson and Prpic defeating Edberg, who lost his No. 1 world ranking to Boris Becker last week.

In another opening-round series, visiting Italy took a 2-1 lead over powerful Germany when Diego Nargiso and Omar Camporese beat Becker and Eric Jelen, 4-6, 6-4, 7-6 (8-6), 4-6, 6-3, in Dortmund. The series will be decided today with the reverse singles.

The teams split Friday's singles. Becker beat Paolo Cane in four sets and Camporese downed Michael Stich in straight sets.

In other first-round matches, doubles victories provided insurmountable 3-0 leads for Czechoslovakia over Austria, Australia against Belgium, Spain vs. Canada and Argentina in its match with New Zealand.

The two remaining World Group matches, defending champion United States at Mexico and Israel at France, were postponed because of the threat of terrorism stemming from the Persian Gulf War. They have been tentatively rescheduled for March 29-31.
