TOKYO -- Debbie Graham, firing 11 aces, upset sixth-seed American compatriot Pam Shriver, 7-5, 6-4, yesterday in the first round of the Nichirei International Ladies Tennis Championships.
Shriver became the second seeded player to lose in the first round. Japan's women's singles champion Kimiko Date, the eighth seed, was eliminated Monday.
Fifth-seeded Laura Gildemeister of Peru, the highest seed competing today, beat Indonesian Yayuk Basuki, 7-5, 7-5, on the hard court of Ariake Colosseum.
No. 7 seed Marianne Werdel of the United States defeated Japan's Nana Miyagi, 6-4, 6-3, in another first-round match.
The hard-hitting Graham, ranked 54th in the world, overwhelmed Shriver, No. 29, with booming serves in the 85-minute match.
"I felt that my serve was very good today," Graham said. "Also, I like the surface, as it suited my ground strokes. She [Shriver] is an attacker, and I needed good ground strokes to pass her."
Shriver said: "She has a big serve. I had my chances at the end of the first set. If I could play it over, I would attack her forehand more."
At 5-5 in the first set, Graham broke service as Shriver hit volleys wide. She then kept her serve without losing a point.
Graham scored the second set's only service break in the seventh game and served two aces in the final game.
In other first-round matches, Rika Hiraki beat Japanese compatriot Misumi Miyauchi, 4-6, 6-4, 6-0; Naoko Sawamatsu downed Mana Endo, 6-1, 6-3, and Czechoslovakia's Andrea Strnadova defeated Japan's Ei Iida, 6-7 (0-7), 6-3, 6-4.
Third-seeded Katerina Maleeva of Bulgaria meets Strnadova and second-seeded Mary Joe Fernandez of the United States plays Patricia Hy of Canada in the second round today.
Top seed Monica Seles, who drew a bye in the first round, plays in the second round tomorrow.
PARIS -- Defending champion and No. 1 seed Conchita Martinez of Spain defeated Patricia Tarabini of Argentina, 6-1, 6-3, in the first round.
In a repeat of last year's final, Martinez, ranked No. 8 in the world, topped unseeded Tarabini. Martinez faces Sabine Hack of Germany in the second round.
