It's a big day for Team USA. Snowboarding prodigy Chloe Kim will go for her first Olympic gold in the women's halfpipe final, and Sochi bronze medalist Kelly Clark will also look for a place on the podium in the event. Also, 18-year-old Maame Biney will hope to make it to the women's 500-meter speedskating final, and luger Erin Hamlin will try to join Chris Mazdzer as a Pyeongchang luge medalist. Here are the key events to follow on Tuesday in South Korea:
Snowboarding
[UPDATE: Chloe Kim wins gold medal.]
Women's halfpipe final (Monday, 9 p.m. ET/Tuesday, 11 a.m. local time): Team USA has a chance to make its first podium sweep at the Pyeongchang Olympics (and fourth in Winter Olympic history) in the women's halfpipe event. Chloe Kim, the heavy favorite to win gold, will lead the charge, followed by veteran Kelly Clark (she won bronze both in Vancouver and Sochi), Maddie Mastro and Arielle Gold (making their Olympic debuts). Chinese snowboarders Cai Xuetong (a medalist at the 2016 and 2017 X Games) and Liu Jiayu (who is ranked second through qualifying and finished fourth in Vancouver) will look to challenge them.
Alpine skiing
Men's Alpine combined, slalom (Tuesday, 1 a.m. ET/3 p.m. local time): Austria's Marcel Hirscher will go into the event as a heavy favorite. He missed gold at the 2017 world championships by .01 of a second, taking home a silver. He will look to win his first Olympic gold on Tuesday. Also watch out for Norway's Kjetil Jansrud (a super-G gold medalist in Sochi), who will fight Hirscher for a place on the top of the podium.
Speedskating
Men's 1500 meters (Tuesday, 6 a.m. ET/8 p.m. local time): A pair of skaters from the Netherlands -- Koen Verweij (the 1500m silver medalist in Sochi) and Kjeld Nuis (the 2017 world championship gold medalist) -- are favorites in this event.
Short-track speedskating
Women's 500-meter final (Tuesday, 7:11 a.m. ET/9:11 p.m. local time): America's new favorite, Maame Biney, qualified for the quarterfinals of the event on Saturday, finishing second in her heat in 43.665 seconds. She will hope to continue her dream run in the quarterfinals and semifinals (held earlier in the day) and make her first Olympic finals. A strong favorite to win this event is South Korea's Choi Min-jeong (Sochi gold medalist in team pursuit), who set an Olympic record as she qualified for the quarterfinals.
Luge
Women's singles (Tuesday, 7:15 a.m. ET/9:15 p.m. local time): Team USA's Chris Mazdzer made history on Sunday, becoming the first American man to medal in a singles luge event at the Olympics. Will Erin Hamlin, Team USA's flag bearer and the first American to win a singles luge medal (in 2014), get Team USA another luge medal? She is in fifth place after the first two runs and will race for a place on the podium on Tuesday. Another athlete to look out for is veteran and event favorite Natalie Geisenberger from Germany. She won gold at the singles event in Sochi and will look to replicate her performance in Pyeongchang. She is the leader after the first two runs.
Cross-country
Women's sprint classic style final (Tuesday, 7:25 a.m. ET/9:25 p.m. local time): USA's Jessie Diggins, who finished fifth in the skiathlon event, will look to win her first Olympic medal in the sprint classic style final on Tuesday. She is the 2017 world championship silver medalist in the event. The heavy favorite remains defending Olympic champion Maiken Caspersen Falla from Norway. Will she win her second consecutive Olympic gold in the event?
Men's sprint classic style final (Tuesday, 7:34 a.m. ET/9:34 p.m. local time): Fans from Norway will be excited for this event -- Norway's Johannes Høsflot Klæbo, 21, and Emil Iversen, 26, are the top contenders. Klæbo won sprint bronze at the 2017 world championships. Their plans to clinch the top two medals at the event might be derailed by Italy's Federico Pellegrino, who is coming off a strong season -- he won the sprint gold at the 2017 world championships.
