NEWPORT, R.I., JULY 11 -- Dan Goldie of McLean, Va., upset third-seeded Wally Masur of Australia, 6-2, 4-6, 6-2, in a semifinal of the Volvo Tennis-Hall of Fame Championships today.

Goldie, the 1986 NCAA singles champion from Stanford, will play in his first Grand Prix final Sunday against Sammy Giammalva of Houston. Giammalva, the world's 96th-ranked player, surprised No. 4 Christo van Rensburg of South Africa, 6-3, 6-1, in the other semifinal.

Goldie, ranked 113th in the world, used a powerful return and a strong two-fisted backhand to dominate the first and third sets.

He broke Masur, a member of the Australian Davis Cup team, in the third and fifth games of the first set.

In the second set, Goldie broke Masur in the fifth game. But Masur, ranked 28th in the world, came back with a break in the sixth and another in the 10th to close out the set.

But in the first game of the final set, Goldie broke Masur's serve at love and went on to a 4-1 lead.

"That was a big game," Goldie said. "It changed the momentum."

"I was surprised a little bit," Masur said. "He did play quite an inspired game."
