Unseeded Lisa Bonder, playing as a professional on the women's tennis tour for a little more than a year, stunned second-seeded Andrea Jaeger, 6-2, 5-7, 6-1, yesterday in Tokyo in the $200,000 Queens Grand Prix Tournament.

Bonder, 17, earned $40,000, the biggest prize of her career. Jaeger, who is ranked third in the world, earned $24,000 in the inaugural of this tournament, an event of the Virginia Slims series.

"I can't say how I feel right now," said Bonder, from Ann Arbor, Mich. "But I'm very happy that I won."

En route to the final, Bonder beat Ann Kiyomura, top-seeded Chris Evert Lloyd and third-seeded Kathy Horvath.

Jaeger expressed displeasure with several line calls, and made numerous unforced errors throughout.

Bonder started the match by breaking Jaeger's service in the second and fourth games with powerful ground strokes. She quickly moved out to 4-0. Bonder took the set by breaking Jaeger for the third time in the eighth game.

In the second set, Jaeger broke Bonder in the first and third games and took a 4-0 lead. However, Bonder won the next five games before Jaeger tied it, 5-5, broke Bonder in the 11th game and took the set by holding service. In the third set, Bonder jumped to a 3-0 lead and easily went on to win . . .

In Palermo, Sicily, second-seeded Jimmy Arias defeated Jose-Luis Clerc, 6-2, 2-6, 6-0, in the final of the $100,000 Sicilian Open. Arias won the Italian Open in Rome and the Tournament of Florence earlier this year . . .

In Irving, Tex., Andres Gomez lost the first set but bounced back to defeat Brian Teacher, 6-7 (7-2), 6-1, 6-1, in the final of the first $200,000 Paine Webber Classic.
