Gymnastics men’s team final kicks off three events for Team USA
Team USA finished fourth in the all-around qualifying competition on Saturday and will be looking to upset Japan and China in the men's team final Monday, July 26, at 6 a.m. ET.
The team combined to post the highest score on floor exercise in qualification. Sam Mikulak (parallel bars), Brody Malone (high bar), Yul Moldauer (floor exercise) and Alec Yoder (pommel horse) qualified for individual events.
Team USA is seeking its first medal in the event since 2008, while host nation Japan is looking to repeat as gold medal winners.
Team USA remains unbeaten in softball
Arguably America’s strongest team through the first weekend of play, the U.S. softball team remained undefeated, with a walkoff win over the host country.
Team USA had already won against Canada, Mexico, Italy and Australia so far. The win over Japan put the team at a perfect 5-0.
The only time Team USA has gone undefeated through the entire tournament was at the 2004 Athens Olympics. The team went undefeated in the group stage at the 2008 Beijing Olympics before falling to Japan in the gold medal game.
Meet Local Olympic Athletes
Katie Ledecky, men’s 4x100m freestyle relay highlight swimming finals
Four more swimming medals were awarded Sunday night, as finals got underway for the women’s 100m butterfly, men’s 100m breaststroke, women’s 400m freestyle and men’s 4x100m freestyle relay.
Katie Ledecky secured her first medal in Tokyo in the women’s 400m freestyle, though it wasn't the one many expected.
The six-time Olympic medalist set the world record in the event at the 2016 Rio Olympics and had the fastest time in Sunday’s qualifying. But she ended up settling for silver in the race after falling to her Australian rival Ariarne Titmus.
The U.S. men repeated as gold medalists in the 4x100m freestyle relay, posting a time of 3:08.97.
Two-time Olympic medalist Caeleb Dressel, who made his Tokyo debut in the event, was a dominating force in the event.
The win gave Team USA its eighth swimming medal of the Tokyo Olympics across men's and women's events.
Eighteen-year-old Torri Huske barely missed the podium in the women’s 100m butterfly. Huske was setting world-record pace throughout most of the race, but faded during the final meters.
The American finished fourth, just one-hundredth of a second out of bronze medal position -- the smallest possible margin in swimming.
Maggie MacNeil of Canada took the gold, becoming the first Canadian to win an Olympic gold medal in the 100m butterfly.
After posting an impressive third-place time in qualifying, Michael Andrew finished just short of the podium in the men's 100m breaststroke Sunday night. Great Britain’s Adam Peaty won the event for the second straight Games.
Sunday’s swimming slate also included semifinals in the men’s 200m freestyle, women’s 100m breaststroke, men’s 100m backstroke and women’s 100m backstroke.
Women’s skateboarding makes Olympic debut
The women’s street event took place a night after the inaugural Olympic men’s street skateboarding competition was filled with falls.
Three Americans competed but all failed to reach the podium: Mariah Duran, Alexis Sablone and Alana Smith.
The three Americans had to contend with favorites like Japan’s Aori Nishimura, who skated into history Sunday night by winning the first ever women's Olympic street skateboarding event in Tokyo.
Team USA's Sablone, a seven-time X Games medalist (winning in 2015, 2012 and 2010) who grew up in Connecticut, finished fourth after scoring 13.57 points. Duran and Smith both missed the cut for the final.
The men’s individual triathlon took place Sunday, with Americans Morgan Pearson and Kevin McDowell appearing as first-time Olympicans.
McDowell finished sixth in the event, which is the best-ever finish by an American in the individual triathlon since its debut in the 2000 Sydney Olympics.
Vincent Luis, the two-time defending world champion, was favored to win gold in his third Olympics, but Norwegian Kristian Blummenfelt won gold with Alex Yee of Great Britain winning silver.
