It was a race of the American superstars.
Dalilah Muhammad topped the world record time in the women's 400m hurdles final on Tuesday night, but it wasn't enough for her to repeat as Olympic champion.
Sydney McLaughlin beat her own world record to win the highly anticipated race and secure her first Olympic medal. McLaughlin took nearly half of a second off her previous world record (51.90 seconds) by finishing in 51.46.
Muhammad, who won gold at the 2016 Rio Games, earned silver with a time of 51.58.
US Women's Basketball Team Routs Australia, Advances to Semifinals
For a team that has won six straight gold medals and more than 50 consecutive games, playing from behind is unfamiliar and unexpected territory.
Yet, after the first quarter in all three games during pool play, the mighty U.S. women's basketball team found itself in that very territory: trailing.
That changed on Wednesday as the U.S. jumped out to an early lead en route to a 79-55 rout of Australia in its quarterfinal matchup at the Tokyo Olympics. The fast start helped secure a spot in the Final Four as Team USA extended its winning streak to 53 games and put itself within two victories of a seventh straight gold medal.
The U.S. advances to the semifinals to face Serbia, which defeated China 77-70 in the quarterfinals, on Thursday at 11:40 p.m. CT.
Bartlett's Zach Ziemek competes in men's decathlon heats
Bartlett's Zach Ziemek began his quest for an Olympic medal in Tokyo in the men's decathlon event after falling short of a medal during the 2016 Rio Games.
He started with competition in the heats for the 100m, long jump, shot put, high jump and 400m.
The Illinois native finished in fourth in his heat with a personal best in the 100m. He went on to place ninth in his long jump group, score another personal best with a fifth-place finish in shot put, tie for second in the high jump and second in his heat for the 400m with a season-best finish. He ended the day's competition just out of the top five spots in terms of points, but there are still several events to go.
Ziemek, who has a degree in nautical engineering, is a four-time NCAA All-American and became the NCAA Champion in 2016.
Competing in the decathlon, Ziemek placed seventh in Rio 2016 Olympic Games.
