Monica Seles upset top-seeded Martina Navratilova, 6-3, 7-6 (7-5), last night in Oakland to win the Virginia Slims of California.
The win by the 16-year-old Seles, a Yugoslav citizen living in Sarasota, Fla., was her third straight over Navratilova.
Seeded second in this tournament and ranked third, she used blistering groundstrokes that had Navratilova, 34, shaking her head.
"I think if there had been any paint on the lines the balls would have turned white," Navratilova said. "I was always playing catch-up. She hits the ball so hard, once you're on the defensive, you're dead."
Seles broke serve in the fourth game of the first set with untouchable returns of serve, but Navratilova got the break back in the seventh when Seles double-faulted. Seles cracked a forehand down the line to take another break in the eighth game to go ahead, 5-3. Navratilova then got three break points on Seles's serve, but couldn't convert them. . . .
Stefan Edberg clung to the No. 1 ranking in tennis by default as Boris Becker "heard something pop" in his thigh before retiring from their final in the first set of the Paris Open.
The strongest field of the year -- 38 of the top 43 players -- was not able to keep Edberg and Becker from meeting again to decide things. The injury did. In the only other tournament final this year in which a participant retired, Edberg pulled out of the Australian Open with a stomach muscle pull, giving Ivan Lendl the Grand Slam victory.
"I think it evens out," Edberg said. "I got hurt in Australia. So I sort have got it back on credit today."
Becker's injury threw doubts over his participation in the year-ending ATP World Championships Nov. 13-18. "I felt something pop at 30-all on my serve at 2-all," said Becker, who left with the first set tied at 3. "I hit a forehand volley. He hit a short return that I came in on and then I heard something pop.
Becker will be examined today by Wolfgang Mueller-Wohlfahrt. "It's a muscle on the left leg on the top of the left thigh," Becker said. "The last two days the right side was worse and I was playing more or less on my left side. I guess it took its toll."
Edberg won $270,000, Becker got $145,240. . . .
Unseeded Natalia Medvedeva became the second straight Soviet to win the Virginia Slims of Nashville singles championship with a 6-3, 7-6 (7-3) victory over fifth-seeded Susan Sloane. Her first singles title was worth $27,000.
Leila Meskhi won the Nashville tournament last year.
In the doubles final, Kathy Jordan and Larisa Savchenko defeated Brenda Schultz and Carolina Vis, 6-1, 6-2.
