PYEONGCHANG, South Korea -- Host country South Korea won its first medal on Day 1 of the Winter Olympics, a unified hockey team made history and records were broken across several sports. Here's what you might have missed Saturday:
Cross-country skiing
Scandinavians swept the women's skiathlon, a 15-kilometer race that requires skiers to switch techniques midway, on Saturday afternoon. Sweden's Charlotte Kalla took home the gold, followed by Norway's Marit Bjoergen, whose silver makes her the most decorated female Winter Olympian of all time, and Finland's Krista Parmakoski. American Jessie Diggins, her signature glitter on her cheeks, finished in fifth place, 14.7 seconds behind Kalla. That's the highest finish in history for an American woman in the sport. Diggins, a favorite to land the U.S. women's first-ever Olympic medal in cross-country skiing, is scheduled to race again on Tuesday in the women's individual sprint.
Men's snowboard slopestyle
With his parents and six siblings cheering him on, 17-year-old Red Gerard became the only American to qualify for the men's snowboard slopestyle finals. The reigning FIS World Cup champ is looking to become the youngest American snowboarder to medal at the Olympics.
Biathlon
Laura Dahlmeier won Germany its first gold in the 7.5km sprint, while the Americans continue their medal drought. (Biathlon is the only Winter Olympic sport in which the U.S. has never medaled.) Susan Dunklee, Team USA's greatest medal hope, started poorly, missing five shots, and failed to qualify for the women's 10km.
Speedskating
The Dutch women swept in the 3,000-meter final as Carlijn Achtereekte edged out defending champ Ireen Wust for gold, while 22-year-old Antoinette de Jong took bronze. Their haul helps put the Netherlands atop the medal table, with four total.
Short-track speedskating
The home crowd's favorite sport did not disappoint. With the North Korean cheer squad in full voice, South Korea dominated the night -- even if it didn't pan out the way they might have expected.
In the men's 1,500-meter final, Hwang Dae-heon, who was heavily favored, crashed late in the race. His compatriot, 21-year-old Lim Hyo-jun, was already ahead, and held his nerve to seize gold, setting an Olympic record of 2:10.485. His victory marks South Korea's 43rd medal in short-track -- out of 54 total.
Olympic Athletes from Russia notched their first medal, as Semen Elistratov took the bronze behind the Netherlands' Sjinkie Knegt.
On the women's side, Britain's Elise Christie put up an Olympic-record time in the 500-meter qualifiers, only to have that benchmark broken by South Korean skater Choi Min-jeong minutes later. American Maame Biney also advanced to the semifinals, which will be decided Tuesday.
All this in front of U.S. vice president Mike Pence, South Korean president Moon Jae-in and -- soccer fans -- Guus Hiddink, the former Chelsea FC manager who led South Korea to the 2002 World Cup semifinals in Seoul.
Women's ice hockey
In the marquee event of the day, the unified Korean team kicked off its first game, with Kim Yo Jong, the sister of North Korean leader Kim Jong Un, and more of the country's cheer squad in attendance. All the talk of peace and harmony didn't stop the Swiss; forward Alina Muller scored a hat trick to put them up 3-0 early.
Curling, mixed doubles
Bad news for Team USA: Sibling curlers Becca and Matt Hamilton's hopes of advancing to the semifinal round are over, despite a strong win over Norway. But it's not the last we'll see of the siblings from Wisconsin. They'll both return to the ice Wednesday in the men's and women's competitions.
