Schild completed her runs on the long "Crveni Spust" course in 2 minutes 1.32 seconds, leaving Slovenia's Tina Maze a distant second at 2:02.72. Michaela Kirchgasser, another Austrian, was third in 2:03.59.
Schild won this season in Aspen, Colo., and then three times in 11 days last month in Europe. The win Tuesday was the 32nd of her career and leaves her two short of the all-time slalom record held by Vreni Schneider, who won 34 times from 1986-95.
Schild, with 500 points, has a commanding lead in the World Cup slalom standings. Maze is second with 287 points followed by Kirchgasser with 205 and Kathrin Zettel, another Austrian, who has 200 points.
American Lindsey Vonn continues to lead the overall World Cup standings with 641 points. She also leads the downhill and super-giant individual lists. Schild is second overall with 540 points and Maze third with 390.
