The first day of the Tokyo Olympic Games looked a lot different than years past due to the coronavirus pandemic. Still, the Games went on Friday, beginning with the opening ceremony and parade of nations in front of a nearly empty stadium. Competition also got underway in men's gymnastics, women's soccer, swimming, tennis and more. Women's soccerThe Americans rebounded from their opening loss with a 6-1 rout of New Zealand in front of the First Lady Jill Biden on Saturday in the women's soccer tournament at the Tokyo Olympics.With the United States leading 2-0 at the break, Biden arrived in time to watch the team put the game away in the second half at Saitama Stadium.The United States was stunned by Sweden in the first match, losing 3-0. It was the team's first loss since January 2019 and snapped a 44-game unbeaten streak. The Americans had not been held scoreless since 2017. Rose Lavelle scored off a well-placed pass from Tobin Heath in the ninth minute to give the United States an early lead — and the team's first goal of the Olympics. Despite the lack of goals, the Americans dominated the half, unlike their out-of-sorts start against the Swedes.Lindsey Horan scored with a header in the final moments of the half to put the United States up 2-0 at the break. It was Horan's 23rd international goal and it came on her milestone 100th appearance for the national team.It could have been worse for New Zealand but the United States had four disallowed goals, all for offside, in the first half.An own-goal by Abby Erceg extended the U.S. lead to 3-0 in the 64th. New Zealand avoided the shutout with Betsy Hassett's goal in the 72nd. Softball Cat Osterman pitched six innings of one-hit ball and Monica Abbott struck out the side in the seventh, helping the top-ranked U.S. shut out No. 5 Mexico 2-0 on Saturday.Ali Aguilar provided a two-run single in the third that was just enough for the Americans to improve to 3-0 as the country tries to regain the Olympic gold medal.“I’m here so they can win a gold medal because I already have one,” said Osterman, the last player remaining from the 2004 champions. “I want to see how they feel and how they react after we are able to possibly do that.” Osterman struck out four, walked one and hit a batter. Pitching without a cap and with a white towel dangling from her back pocket on a 90-degree, humid afternoon, she retired her final 15 batters.She escaped her only trouble in the second, when Suzannah Brookshire worked out an eight-pitch walk leading off and Victoria Vidales reached on an infield single that went off the glove of Kelsey Stewart at third. Chelsea Gonzales fouled out, Sashel Palacios took a called third strike and Stefania Aradillas struck out. Mexico, a team with many U.S. college players and veterans of the American player development program, dropped to 0-3 in its first Olympic tournament. Haylie McCleney had two more hits and is 6 for 9. Mexico shortstop Anissa Urtez, who is engaged to U.S. right fielder Amanda Chidester, made a diving backhand stop to rob McCleney of a hit leading off the fifth.Dejah Mulipola, getting her first start, walked leading off the third and McCleney singled before O’Toole replaced Dallas Escobedo (0-2).O’Toole struck out Janie Reed and got Chidester to ground out, then intentionally walked Valerie Arioto. Aguilar followed with a single to center.After pushing across just five runs in three games, the U.S. plays Australia on Sunday and host Japan on Monday to complete the group stage. The top two nations advance to Tuesday’s gold medal game.
