Seles Falls, Agassi to Lose No. 1

TOKYO -- Iva Majoli of Croatia defeated world No. 1 Monica Seles of the United States on Friday, advancing to the semifinals at the Toray Pan Pacific Open women's tennis tournament in Tokyo.

Majoli, 18, the world No. 8, upset Seles 1-6, 7-6 (7-5), 6-4 in a quarterfinal match.

The 22-year-old Seles, who won the Australian Open women's singles title last week, entered the Pan Pacific Open with a sore left shoulder. She pulled out of the doubles event, saying her shoulder was very painful.

Meanwhile, because of a scheduling quirk, Andre Agassi will lose his world No. 1 spot to Austria's Thomas Muster in the next ATP Tour rankings.

Agassi, who took over as No. 1 from Pete Sampras at the Australian Open last week, will drop to third when the rankings are published Feb. 12.

The reason for the change is that the tournament in San Jose, California, is being played a week later this year because first-round Davis Cup matches are scheduled for the weekend of Feb. 9-11.

As a result, Agassi will lose the 204 computer points he picked up for winning in San Jose last year.

That will drop him from 4,495 points to 4,291. Muster, No. 2 in the current rankings, has no points to defend next week and will become No. 1 for the first time in his career with 4,474.

Sampras will move from No. 3 to No. 2 with 4,465. Boris Becker, winner of the Australian Open, will stay at No. 4.

Muster will become the 13th player to hold the No. 1 spot since the inception of the computer rankings in 1973.
