But as the world knows by now, Shiffrin does more than just the minimum.
Saturday's result stretched the American's lead over Vlhova in the slalom standings to 225 points with just the season-ending race at the World Cup finals in Sweden remaining.
Shiffrin won gold in the giant slalom and silver in the combined event at last month's PyeongChang Olympics.
The three-time Olympic medalist did so with five races left in the World Cup season. Looking for breaking news, videos, Olympic and Paralympic team bios all at your fingertips?
She came into the race with a 561-point overall lead over Switzerland's Wendy Holdener, in second place. Sweden's Frida Hansdotter rounded out the podium in third.
Shiffrin, who turns 23 on Tuesday, set a World Cup record on Saturday as she became the first 22-year-old skier, male or female, with 42 World Cup wins. Norway's Ragnhild Mowinckel won the event by 0.74 of a second, her first career victory. Holdener failed to win or finish in second place, which was the only mathematical chance Shiffrin could be knocked out of contention.
The World Cup finals begin Wednesday with women's and men's downhill, and the season concludes next Sunday. The win was her 11th this season, her sixth in eight slaloms. "My biggest challenge this year has not been the Olympics, or the (World Cup) overall or any of that, but getting motivated for these last races". Lindsey Vonn, who did not race this weekend but will be in Are, holds the record of 81 wins. "The best thing for me now is to have the crystal globe already locked in".
