Zina Garrison, after losing in singles, teamed with Gigi Fernandez to beat the world's No. 2 doubles team yesterday, giving the United States a 2-1 victory over the Soviet Union and a successful defense of the Federation Cup in Norcross, Ga.

Garrison and Fernandez defeated Natalia Zvereva and Larisa Savchenko, 6-4, 6-3, to give the United States its 14th Cup in the tournament's 28-year history.

The Americans were forced to win the doubles after Zvereva rallied past Garrison, 4-6, 6-3, 6-3. Jennifer Capriati earlier downed Leila Meskhi, 7-6 (7-3), 6-4.

"They told me I didn't let anyone down," Garrison said. "It was 2-1. It doesn't matter how you win it."

Garrison and Fernandez trailed by 3-2 in the first set, then won four of the last five games to get the upper hand. They captured the second set easily, taking control with a break in the fourth game for 3-1.

"This is about as high as it gets," Fernandez said.

Said Zvereva: "It was disappointing. . . . I just couldn't play my best {in doubles}. The first set I wasn't all there."

But 12th-ranked Zvereva was all there in the singles, dominating No. 5 Garrison in the second and third sets, winning in 1 hour 55 minutes.

The Soviet broke serve in the third, seventh and ninth games of the second set, then raced to a 4-0 lead in the third.

Capriati lost the first two games but fought back against Meskhi, who was within a point of losing the first set in the 10th game. Both players then held serve, necessitating the tiebreaker.

Capriati won the first two games of the second set, lost two of the next three, then closed it out by winning three in a row. She finished 5-0 in her first Federation Cup.

Canadian Open:Michael Chang overcame 104-degree heat and Jay Berger, 4-6, 6-3, 7-6 (7-2), in the final in Toronto.

"The heat was tough, but it was hot for both of us. I just didn't concentrate enough," said Berger after the 2-hour 50-minute match.

Half of the 12 service breaks in the match occurred in the 77-minute third set. Chang, seeded seventh, had three breaks in the set, but Berger, seeded fourth, overcame each with breaks of his own to tie.

Chang was in a third straight marathon. He won his two previous matches after dropping the first set, eliminating top-seeded Andre Agassi in the quarterfinals and fifth-seeded Pete Sampras in the semifinals.

"I get a lot of my character from mom. She's the type of person who doesn't like to lose. When I grew up, if I beat someone, 6-0, 6-1, I wanted it to be 6-0, 6-0. When I got an A, I wanted an A-plus."

In the tiebreaker, Berger failed to land a first serve on four of his five services and Chang converted each into a point. He double-faulted to give Chang a 3-1 lead and committed five unforced errors in the tiebreaker.

Overall, Berger had 49 unforced errors.
