The Slovenia team won the first ski jumping competition of the season in Klingenthal, Germany, on Saturday after high winds forced the second round to be cancelled.
Slovenian veteran Robert Kranjec had given his side a first-round lead with 540.6 points after producing the longest jump of 141.5m, while Germany, on 528.3pts, finished second with Japan third, on 523.6pts, after the first-round placings proved to be the final results.
World champion Austria, led by world number one Gregor Schlierenzauer, had to settle for fifth with fellow powerhouse Norway sixth.
Finland's veteran Janne Ahonen posted a jump of 110m on his return to competition after a two-year absence as Finland finished eighth.
Schlierenzauer launches the defence of his Crystal Globe on Sunday in the first individual competition of the 2013-14 World Cup season ahead of next February's Winter Olympic Games in Sochi.
