Jamaica’s Elaine Thompson-Herah is now the fastest woman alive.

Thompson-Herah set a new Olympic record in the 100-meter final Saturday in Tokyo, crossing the finish line in 10.61 seconds to win the gold medal. The previous record had stood since the 1988 Olympics when American sprinter Florence Griffith Joyner won gold in 10.62.

Thompson-Herah successfully defended her Olympic title from Rio five years ago. Her time of 10.61 is also the second-fastest by a woman in history.

In a clean sweep for Jamaica, Shelly-Ann Fraser-Pryce clocked in at 10.74 in second place while Shericka Jackson ran a personal best of 10.76 for the bronze medal.

From gold medal favorites to a devasting disqualification.

Team USA’s 4×400-meter mixed-gender relay team left the track in shock on Friday night after being DQed in the prelims and Olympic debut of the event on Friday.

But early Saturday morning in Tokyo, it was announced that the relay team had been reinstated after successfully appealing a ruling that had knocked them out of the Olympics.

After the Americans finished the race Friday, winning their heat handily, race officials disqualified the U.S. team, saying they had committed a zone violation.

“For all takeovers, athletes are not permitted to begin running outside their takeover zones, and shall start within the zone,” World Athletics Technical Rules 24.19 states. “If an athlete does not follow this Rule, their team shall be disqualified.”

It was the exchange between the first leg Elija Godwin and second leg Lynna Irby that was found to have taken place outside the passing zone.

The U.S appealed its disqualification from the first round and hours later learned that the call was reversed.

In a tweet, U.S. Track and Field said the team had been reinstated and would compete in Saturday’s final. Now, many are saying the race could give Allyson Felix a chance to win a historic gold medal. Felix is currently tied with Merlene Ottey for the most medals in Olympic track and field history with nine.

While the legendary sprinter did not compete in the relay prelims, teams can switch up runners between rounds, allowing for more than four athletes to win medals. Felix may be one of them.

Two days after USA Water Polo’s loss to Hungary — their first loss in 13 years — captain Maggie Steffens stepped up and made her mark on Olympic history.

Steffens, a two-time gold medalist playing in her third Olympics, scored four goals in the Americans’ dominant 18-5 win over the Russian Olympic Committee on Friday.

With her 48th career goal, she became the sport’s all-time leading scorer in the Olympics, surpassing Italy’s Tania Di Mario. Steffens did it all with a broken nose, which she sustained during Wednesday’s loss.

Steffens and Team USA stand atop the women’s tournament Group B after going 3-1 through the preliminary round. They’ll next play in the quarterfinals on Tuesday, with a chance to compete for their third straight Olympic gold medal in Tokyo.

Simone Biles wants the world to know she didn’t quit.

In an Instagram story posted on Friday morning, the gymnast wrote that her “mind and body are simply not in sync” and explained in more depth what has plagued her performances since she arrived in Tokyo for the Olympics.

Earlier this week, Biles withdrew from Tuesday’s team all-around final following a stumble during a vault routine. She later pulled out of Thursday’s individual all-around competition to focus on her mental health.

Biles reiterated in her post that she didn’t quit competing because of a bad performance.

“I’ve had plenty of bad performances throughout my career and finished the competition. I simply got so lost my safety was at risk as well as a team medal,” she wrote.

Biles also posted a video of her practicing on the uneven bars on Friday morning. During the training session, she attempted a 1½ twist and fell on her back.

“I don’t think you realize how dangerous this is on hard/competitive surface,” she commented on the video.

“Physical health is mental health,” she continued.

Biles said the phenomenon in which a gymnast’s body gets lost in the air, which she calls “the twisties,” can be disastrous and cause serious injuries during airborne routines.

During Biles’ vault in the women’s team final Tuesday, “the twisties” caused her to underrotate.

“I also have no idea how I landed on my feet on that vault because if you look at the pictures and my eyes you can see how confused I am as to where I am in the air,” she wrote. “Thankfully I landed safe enough but I also don’t think some of you realize I was supposed to do a 2½ and I only completed 1½ twists before it looks like I got shot out of the air.”

On Thursday, Biles and her USA teammates cheered on Suni Lee, who won gold in the individual all-around event.

Bowerman Track Club teammates Karissa Schweizer and Elise Cranny have qualified for Monday’s 5,000-meter final.

Schweizer, 25, finished in a time of 14:51.34 for seventh place in her preliminary heat Thursday. While the top five finishers of each heat earn automatic qualification, the NCAA legend was able to sweat it out with a time qualifier to clinch a spot in the final round.

Schweizer is coming off of a second-place finish at the U.S. Olympic Trials but has the fastest personal record of the American women, running 14:26.34 in 2020.

Cranny and Rachel Schneider, another American, raced together in the second heat.

Through the first 2,000 meters of the race, Cranny and Schneider’s heat was several seconds slower than Schweizer’s.

But Cranny, 25, was able to snatch a fourth-place finish and automatically qualify for the final. The former Stanford standout is coming off of a dominant victory at the U.S. Olympic Trials and a personal best of 14:48.02 in 2020.

Schneider’s finish, meanwhile, left her without a qualifying spot.

Schweizer and Cranny now head into Monday’s 5,000-meter final, where they will compete against a stacked distance field.

All three American sprinters competing in the opening round of the 800-meter event on Friday earned qualifying spots for the semifinals.

The triple threat consists of 19-year-old Athing Mu, ten-time University of Oregon All-American Raevyn Rogers and 800-meter U.S. record holder Ajeé Wilson.

Mu was barely out of breath as she cruised to a 2:01.10 first-place finish during Heat 3 of the first round.

Mu survived some early bumping, looking comfortable as she zoomed to the front of the pack to remain in control of the race. The young favorite went on to beat veteran Canadian middle-distance runner Melissa Bishop-Nriagu, who placed fourth in the same event at the Rio Olympics.

Rogers, also making her Olympic debut, won her heat in 2:01:42 and earned the top qualifying mark out of Heat 4. The 800m silver medalist from the world championships looked poised as she breezed down the final stretch.

Wilson was the fastest American on Thursday, clocking in at 2:00.02 to finish second in Heat 6 and secure her spot in the next round.

Wilson’s qualifying time was the third-fastest posted in the opening round, just behind Jamaica’s Natoya Goule and Great Britain’s Jemma Reekie.

The semifinals, featuring 24 women, are scheduled for Saturday. The final of the 800 meters will be on Tuesday.

Team USA’s women’s basketball team has done it again in Tokyo.

The Americans defeated Japan 86-69 in group play on Friday for their 51st straight win at the Olympics.

“Japan is a tough team to play against,” U.S. coach Dawn Staley said after the game. “After the first quarter, I thought we did a great job disrupting them and not allowing them to take and make as many 3-point shots uncontested. We just forced them to put the ball on the floor and then our bigs got involved.”

Staley continued: “I was happy that we locked down and got that done. I’m happy for our team because we are slowly coming together and playing the style of play we need to play to not only get better, but just compete and to get out of pool play because we’ve got a tough pool.”

Japan, in its fifth Olympic appearance, came on strong in the first quarter. They went 6-for-10 on 3-point attempts and had the U.S. on their heels defensively.

But the Americans hit their stride heading into halftime and pulled away in the second half.

A’ja Wilson led the way for the U.S. with 20 points and 10 rebounds, following up on her dominant performance in their Olympic opening win over Nigeria.

Breanna Stewart had 15 points, 13 rebounds and six assists. Brittney Griner also stepped up with 15 points, while Jewell Loyd had 12 and Diana Taurasi finished with 11.

At the break, the Americans led 49-40.

Japan quickly made up the deficit in the third quarter, but they weren’t able to get any closer as Wilson, Stewart and Griner helped Team USA break away. The American trio combined for 50 points and 28 rebounds.

Although it took until the second half to build a comfortable lead, the U.S. players were confident in their progress.

“Just communication,” Loyd said of the team’s biggest improvement. “One, we’re getting used to the ball — which is different from the WNBA — and then two, just working on making sure we’re just calling for each other [on defense] and understanding personnel a little bit better and kind of taking a breath. I think we played a little fast in other games, so just trying to get a rhythm for us and take it slow and play our speed.”

Team USA next faces France on Monday.

Canadian goalkeeper Steph Labbè made it happen for Team Canada on Friday.

The 2016 bronze medalist saved two do-or-die penalty kicks to help her team beat Brazil and power through to the Olympic semifinal round in Tokyo.

In the first game of the tournament’s knockout stage, the teams were scoreless during regulation, but Brazil challenged Canada during overtime and eventually into penalty kicks.

Marta, Debinha, and Erika converted their PKs to give Brazil the lead before Labbè, 34, made a clutch save on Andressa’s PK.

Jessie Fleming, Ashley Lawrence, Adriana Leon, and Vanessa Gilles scored for Canada, setting up Labbè’s stunning save against Brazilian defender Rafaelle to seal the win.

It’s the second time in three games that the Canadian netminder has made a critical PK save to help Canada secure a win.

The Canadians will face the United States in the semifinals on Monday at 4 a.m. ET.

After the USWNT qualified for the knockout stage with a 0-0 draw with Australia on Tuesday, forward Alex Morgan talked about the team’s tactical strategy in the final group stage game.

While Australia out-possessed and outshot the USWNT in the game, Morgan said goal prevention was part of their plan as they looked ahead to the quarterfinals.

“This (knockout stage) is when the tournament starts,” Morgan said at a news conference after the game. “It was a tactical decision by (coach Vlatko Andonovski) to shift defensively, a little more conservatively, and really allow them to get impatient, play along and give it back to us.

“Eventually, I feel like both teams kind of sat in, and it became a matter of playing a professional game and moving on. It’s seeing how Vlatko wants us to set up against that (next) team. Tactically we had a little shift this game, we’re experienced enough and professional enough to be able to do so and face a team in a way that puts us on top and really plays to our strengths.”

The U.S. will face Vivianne Miedema and the Netherlands on Friday. The two teams previously met in the 2019 World Cup final, which the USWNT won 2-0.

Following Team USA’s 81-72 preliminary-round win over Nigeria, their 50th straight victory at the Olympics, Sue Bird confirmed that the Tokyo Olympics would be her last.

Selected as one of two flag bearers for the U.S. at the opening ceremony, Bird, 40, is playing in her fifth Olympics and has already brought home four Olympic gold medals.

“After the last couple years, after Rio, at that point, I was, whatever, I was, 36 or so, people started asking questions about how much longer you’re going to play,” Bird told reporters after the game. “I always said I was going to take it year by year.

“As long as I was healthy and still playing at a high enough level, an elite level to be selected by the team, of course, I was going to accept that.”

When asked again if the Tokyo Olympics would be her last, she answered: “Yeah.”

Team USA coach Dawn Staley, who played with Bird at the 2004 Olympics, said to “never count Sue out.”

“I know she said that, but she continues to play and she continues to play well, and if it indeed is her last Olympics, I surely would like to send her off into the sunset, winning another gold medal for her,” Staley said.
