Pam Shriver posted her first career victory over Chris Evert, scoring a 6-4, 6-1 semifinal triumph yesterday at the $280,000 Canadian Open in Toronto.

Shriver, the No. 3 seed, had failed to beat the top-seeded Evert in their previous 18 matches dating back to 1978.

"I just played a very intelligent match," said Shriver, ranked No. 5 in the world. "You have to play an almost perfect match to beat her -- I know because I've played 18 unperfect matches against her. I was beginning to think Chris would be retired before I'd ever be able to beat her."

Shriver, of Lutherville, Md., will face No. 5 seed Zina Garrison today in the final. Garrison defeated eighth-seeded Bettina Bunge, 6-2, 6-3, in the other semifinal.

Shriver had two service breaks in each set against Evert. The most dramatic came in the final game of the opening set, which went to deuce six times . . .

Stefan Edberg routed Jimmy Connors, 6-2, 6-3, to move into the final of the ATP Championship in Mason, Ohio. Edberg, the No. 2 seed, will face third-seeded Boris Becker, who defeated Anders Jarryd, 6-3, 6-3.

Service breaks in the second and eighth games gave Edberg the first set. Edberg broke Connors, seeded fourth, to make it 3-1 in the second set and served out for the match.

Connors hobbled during the match. He said: "I just wasn't getting around too well today. It was a little thing on the bottom of my {right} foot."

Becker had five aces to beat eighth-seeded Jarryd for the first in their last three matches.
