Per Bergerud of Norway won the 90-meter World Cup event, reduced to one run by bad weather at Engelberg, Switzerland. Bergerud leaped 115 meters to pick up 130.8 points, good enough to beat Jeff Hastings of Norwich, Vt., who earned only 129.3 points despite clearing the same distance. East Germany's Stefan Stannarius was third with 126.2 points from a jump of 113.5 meters . . .
At Kranjska, Yugoslavia, Franz Gruber pulled off a surprise in a World Cup slalom race, winning in an aggregate time of 1 minute 28:62 seconds; that followed Gerhart Pfaffenbichler's downhill victory Friday in Sarajevo and yesterday's giant slalom victory by Hans Enn in Kranjska Gora. Sweden's Ingemar Stenmark, Yugoslavia's Bojan Krizaj and Phil Mahre of the U.S. all fell on the first run . . .
At Les Diablerets, Switzerland, Maria-Rosa Quario of Italy won a rain-marred slalom for her first World Cup victory since 1979. She finished ahead of Hanni Wenzel of Liechtenstein, who won the weekend's combined slalom-downhill race. Maria Maricich, the U.S. hope for the World Ski Cup downhill competition, broke a collarbone in Saturday's downhill and will be unable to compete again this season, a spokesman said.
