The Austrian superstar took victory in a slalom in Saalbach-Hinterglemm to earn his 63rd World Cup win overall Thursday.
Hirscher sits third on the list of most successful skiers on the World Cup circuit, 19 wins behind Lindsey Vonn, who is retiring after the Lake Louise event in 2019.
The record holder is Sweden’s Ingemar Stenmark with 86 victories.
Hirscher led after a barnstorming first run at Saalbach and had plenty in hand to beat France’s Loic Meillard by 0.38 seconds.
His long-time rival Henrik Kristoffersen of Norway was 0.47 seconds adrift in third.
Hirscher, a double Olympic champion from PyeongChang 2018, is also bidding to defend his world titles in slalom and giant slalom at February’s World Championships in Are, Sweden.
