PYEONGCHANG, South Korea — Two events, two gold medals for Marcel Hirscher. The 28-year-old Austrian has a good chance to leave the Pyeongchang Olympics with one more. Hirscher won the men’s giant slalom Sunday , finishing in 2 minutes, 18.04 seconds, and beating Norway’s Henrik Kristoffersen by 1.27 seconds — the largest victory in the event at an Olympics in 50 years .
