The 2020 Olympic Games are officially underway, one day after the Opening Ceremonies in Tokyo. It was a slow start for Team USA, which finished without a medal on the opening day for the first time since 1972 thanks in part to an upset in men’s sabre and a rough finish in women’s weightlifting.

The Olympic swimming meet kicked off Saturday with preliminary heats in six events, and the Americans avoided any missteps with all 10 swimmers who raced advancing to the next round.

The U.S. men’s gymnastics team also opened competition Saturday and advanced to the team final in fourth place. After a shaky start, Team USA delivered an exceptional floor rotation and then held steady through pommel horse. And the U.S. women’s soccer team bounced back with a win over New Zealand. The Americans now sit in second place in Group G with one group stage match to go.

The dignitaries are still a major part of the festivities: U.S. first lady Jill Biden appeared Saturday at the three-on-three basketball venue to cheer on the American team against France. She also watched the U.S. women’s soccer team defeat New Zealand, 6-1.

Tennis player Novak Djokovic won his first match as his quest for a rare “Golden Slam” continues. The United States softball team improved to 3-0 with a 2-0 win over Mexico, and still hasn’t allowed a run. The U.S. women’s water polo team turned in a record-setting performance against Japan.
