A 19-year-old Dallas woman, in her debut on the women's winter professional tennis circuit, upset third-seeded Betty Stove last night in the Avon championship of Washington.

Anne Smith, who turned pro last fall after one season of college play, defeated Stove. 6-7, 7-5, 6-3, before 2,810 persons at George Washington University's Smith Center.

In other first-round matches Pam Shriver of Lutherville, Md., clipped Francoise Durr, 6-2, 6-4, and Martina Navratilova took only 34 minutes to demolish Lea Antonoplis, 6-1, 6-0.

"It is my biggest win, the best I've played in a long time," Smith said, while Stove was unhappy with her erratic serves.

"I missed a lot of serves," the 33-year-old Stove said. "I got a little lazy. I was stuck in Europe the day before yesterday and didn't get here until late last night. I had wanted an extra day's rest."

For Shriver, 16, last night's match was her first in a tournament since September, when she was beaten in the U.S. Open final by Chris Evert.

Although she has played in two team events since, Shriver said, "It's hard to get your rhythm back when you don't play as regularly. I've never played on a circuit before... I've never really had a chance to get into it like everybody else week in and week out.

"It's kind of like starting all over again in this tournament except that you're not starting all over at the bottom. You're at the top."

Shriver said she has not set any goals for this tournament, but acknowledged she would like to break 16-year-old Tracy Austin's 9-0 streak of wins over her. That could be accomplished if both advance to the quarterfinals.

"If I get by Tracy, I think I'll have a good shot at the tournament title," Shriver said.

Durr, 36, said she did not know what to expect from Shriver, who kept her running all over the court.

"I haven't played in the last three weeks," Durr said. "I think it's better to lose against Pam than somebody I should not have lost against.

While her colleagues were battling fatigue, Navratilova was fighting off a cold. But it failed to hamper her near-flawless match that included only one missed volley and three ground-strokes.

"There's something that just clicks every time a new year comes," Navratilova said. "I get eager all over again.

There is such a psychological letdown after Wimbledon and the U.S. Open that I get anxious to play again."

Navratilova said this year she wants to be seeded No. 1 on the computer list "and in the minds of every single person in the world. I'd also like to win the U.S. Open or Wimbledon -- take one of them. As long as I stay healthy, the goals are attainable."
