Dan Goldie of McLean, the 1986 NCAA singles champion, won his first professional title yesterday when he defeated Sammy Giammalva, 6-7 (7-5), 6-4, 6-4, in the finals of the Tennis Hall of Fame Championships in Newport, R.I.

Goldie, ranked No. 113 in the world, earned $20,000. Giammalva, ranked No. 96, got $10,000.

Goldie, 23, won the NCAA title at Stanford and then turned professional last year. He lost in the first round of this tournament in 1986.

"This is a lot different than college," Goldie said. "It's a pro title. It's on grass. I've never won a tournament on grass before. It's at a real historic place. A lot of great players have played here and it's a real honor to be on the list of champions. It feels really good."

Neither player lost his serve in the first set, with Goldie saving two break points in the fifth game. Giammalva won points in Goldie's serve twice in the tie breaker, however, to win the set.

Goldie bounced back in the first game of the second set and broke Giammalva on the 15th point of the game. He broke Giammalva again in the fifth game.

Giammalva, 24, who double faulted 12 times in the match, lost his serve in the third and fifth games of the final set but broke Goldie in the sixth. He had a break point in the eighth before Goldie held serve.

Goldie served to a 40-0 lead in the last game, but Giammalva hit two winners and Goldie foot-faulted for deuce. Goldie won the next two points to finish the match.

U.S. Pro Championships:

Changing from a patient approach in the first set to an attacking strategy in the second, Mats Wilander beat fellow Swede Kent Carlsson, 7-6 (7-5), 6-1, to win the title in Brookline, Mass., for the second time in three years.

It was the fourth title this year for the top-seeded Wilander, ranked second in the world, and the 17th of his 25 career titles on clay. He won 11 of the last 14 games over the third-seeded Carlsson, 19.

Carlsson broke Wilander's serve to take a 4-2 lead in the first set. But Wilander broke right back on Carlsson's wide cross-court forehand. Carlsson was up, 5-4 and 0-30, on Wilander's serve in the 10th game. But Wilander won the next four points to pull out the game.

Swiss Open:

Third-seeded Emilio Sanchez defeated Ronald Agenor, 6-2, 6-3, 7-6 (7-5), in Gstaad, Switzerland, to win the $230,000 tournament.
