Team America's hopes of making the North American Soccer League playoffs all but evaporated tonight here at sweltering Soldier Field.

Playing in 102-degree heat, the Chicago Sting put on an offensive show in the first half and scored a 3-0 victory before 21,913 spectators, its largest home crowd of the season.

This 11th loss in the last 12 games left Team America 36 points behind Montreal in the struggle for the eighth and final playoff spot. There are only five games left and the most Coach Alkis Panagoulias's low-scoring team can accumulate is 45 points--by winning all of its matches and scoring at least three goals in each.

Goalie Victor Nogueira of the Sting (14-11) stopped seven shots in recording his second shutout victory of the season. It was the eighth game in which Team America (9-16) failed to get a goal.

"Chicago's goalkeeper was very impressive," said Panagoulis. "He's one of the best I've seen. He comes out of his goal a lot and that's good.

"Two of their goals were silly. If you give up goals like that against that team so early, the game is gone before it's started. Our gu w0112 ----- r g BC-08/20/83-SOCCER 08-20 D02 Sting Too Much For Team America By Neil Milbert Special to the Washington Post

CHICAGO, Aug. 19--Team America's hopes of making the North American Soccer League playoffs all but evaporated tonight here at sweltering Soldier Field.

Playing in 102-degree heat, the Chicago Sting put on an offensive show in the first half and scored a 3-0 victory before 21,913 spectators, its largest home crowd of the season.

This 11th loss in the last 12 games left Team America 36 points behind Montreal in the struggle for the eighth and final playoff spot. There are only five games left and the most Coach Alkis Panagoulias's low-scoring team can accumulate is 45 points--by winning all of its matches and scoring at least three goals in each.

Goalie Victor Nogueira of the Sting (14-11) stopped seven shots in recording his second shutout victory of the season. It was the eighth game in which Team America (9-16) failed to get a goal.

"Chicago's goalkeeper was very impressive," said Panagoulis. "He's one of the best I've seen. He comes out of his goal a lot and that's good.

"Two of their goals were silly. If you give up goals like that against that team so early, the game is gone before it's started. Our guy (goalkeeper Paul Hammond) stayed in the goal on the second one (scored by Ricardo Alonso). When you do that, you're condemned, but I still see goalkeepers doing it all the time."

In addition to scoring his 16th goal on a head shot at 25:59, Alonso made the pass that set up the 20-yard kick by Seninho, putting Chicago in front with 2:30 elapsed. Pato Margetic completed the Chicago scoring with a short thrust at 34:57 after his dribbling dissolved the Team America defense.

"The thinking in building Team America should be redone," said Chicago Coach Willie Roy. "They need a couple of international caliber offensive players . . ."
