SEATTLE, JULY 25 -- Ramon Rivas scored 34 points and had 18 rebounds tonight as Puerto Rico beat the Soviet Union, 99-84, in the final basketball qualifying round game at the Goodwill Games.

The game didn't have any bearing on the placements for the medal round as the Soviet Union (2-1) already had clinched the top spot in its pool, and Puerto Rico was relegated to the classification round.

Rivas, who played at Temple and briefly with the Boston Celtics, shot 12 for 18 from the field and led Puerto Rico (1-2) to a 44-31 rebounding advantage.

The Soviets, who played their starters for most of the game, led by 47-43 at halftime but Rivas dominated the second half on the inside, scoring 26 points. . . .

Oscar Schmidt scored a Goodwill Games-record 42 points as Brazil went through the qualifying round undefeated with a 101-94 victory over Australia. Australia, led by Andrew Gaze's 28 points, finished the qualifying round without a victory.

Brazil (3-0) will meet the United States, which defeated Italy, 113-76 tonight, in Friday's semifinals.

Yugoslavia advanced to the medal round with an 81-67 victory over Spain. Yugoslavia (2-1) will face the Soviet Union in Friday's semifinals in a rematch of the gold-medal game at the Seoul Olympics. The Soviets won that game after losing to the Yugoslavs in the qualifying round.

A Conspiracy of Sorts

Three Americans and two Soviets in the first 100-meter heat of the decathlon staged an international conspiracy of sorts.

They knew gusty headwinds at Husky Stadium would slow them and cost them points.

"We were talking back and forth in the set position," U.S. champion Dave Johnson said. "We would say, 'Is it too windy?' Someone would say, 'Yeah, yeah, let's false start.' Boom! Someone would false start."

The five decathletes collected six false starts before they got the wind conditions they wanted.

Seattle on $7.50 a Day

Soviet athletes at the Games may be among the best in the world, but the spending money they're given is anything but world class.

Most of the Soviets are given about $7.50 a day to spend. For that, you might get a trip up the Space Needle and a cheap hamburger.

"It's definitely hard to realize you are a world-class athlete with just 75 dollars in your pocket to spend over 10 days," Andrei Shchepkin, a top team handball player, told the Seattle Times.

The Soviet athletes can earn more in some sports -- if they win. A gold medal is worth $1,200, a silver $750 and a bronze $400.

Marathoners such as Nikolai Tabak, who placed second in Saturday's men's marathon, can earn even more through a special arrangement. Tabak's performance, for example, will earn him $3,000, half of what The Athletic Congress of the United States would award for the same spot.

Still, that's more than Tabak said he would have received two years ago, when the Soviet Sports Committee returned only 15-20 percent of what athletes earned.

"Perestroika has finally reached sports," Tabak said with a smile.
