Ted Ligety of Park City remained third overall after finishing 11th, 2.44 behind Hirscher. The American, who won Saturday's giant slalom, has 179 points to make up on the defending champion midway through the season.
"Eleventh place isn't my goal, that's for sure," Ligety said. "In order to really make everything meaningful, in slalom I need to be doing a lot better in order to make an impact in the overall."
American teammate David Chodounsky placed 10th for his best World Cup result in an injury-hit career at age 28.
In St. Anton, Austria, Tina Maze of Slovenia reached another milestone in her stellar season by winning her first super-G and becoming the sixth female skier to win a World Cup race in all five Alpine disciplines.

It was the sixth victory of the season and 17th overall for Maze, who was on a super-G podium eighth times before without winning one.
Fabienne Suter of Switzerland trailed Maze by 0.99 and beat defending overall champion Lindsey Vonn by 0.01 for third place.
