Teresa Edwards led the sharpshooting as the United States women's basketball team connected on 60 percent of its shots yesterday in Seattle to beat Australia, 103-80, at the Goodwill Games.

The Americans (3-0) will play Bulgaria, an 85-79 loser to Brazil, in Saturday's semifinals.

Edwards, a member of the 1988 U.S. Olympic gold medal-winning team, sank four of six three-pointers in a game that included some heated exchanges between American and Australian players. She led the U.S. team with 16 points.

In their first two games, the U.S. team was three for 13 from three-point range. But U.S. shooters made eight of 14 against Australia, including two of three by Cynthia Cooper and two of four by Jennifer Azzi.

Australia Coach Adrian Cadee said he decided to work on denying the Americans inside baskets because of their poor outside shooting in earlier games against South Korea and the Soviet Union.

"I've seen them play two games and I could count the number of baskets they'd scored outside the key on one hand," Cadee said. "Everything was inside, with either their power game or their transition. I decided we had to take their strength away from them and make them play from outside, and they did. They hit three-pointer after three-pointer."

Edwards led six Americans in double figures. Medina Dixon scored 15 points.

Shelley Gorman of Australia (0-3) led all scorers with 21 points.

The Americans never trailed, building a 26-9 lead in the game's first eight minutes. . . .

Ulana Semonova, the 7-foot Soviet center who dominated women's basketball for many years, arrived in Seattle this week without tickets to any events. She ended up attending the United States-Soviet Union game with tickets from the U.S. Basketball Federation.

Drug Testing: The drug testing program at the Goodwill Games is seriously understaffed because of lack of money and cooperation from Turner Broadcasting System, the woman in charge of the program said.

Jeanette Grice, coordinator of drug testing for the U.S. Olympic Committee, said organizations sponsoring events like the Olympics and Pan American Games pay for drug testing. But TBS refused, so the USOC took on the job at a cost of $200,000, she estimated.

TBS officials insisted they said from the start they would not get involved in drug testing. "Our role is as host broadcaster," said spokesman Bob Dickinson.

Diving: Gao Min of China, winner already of the 3-meter springboard, won the 1-meter board with a score of 508.80. The top American, Wendy Lucero, was fourth.
