PARIS — Simone Biles and the rest of the U.S. women’s gymnastics team walked onto the floor at Bercy Arena on Sunday in leotards adorned with thousands of crystals, the kind designed to attract as much attention as possible.

Don’t mistake all that glamour — both on the floor and in the stands, where Tom Cruise and Ariana Grande were among those who took in the spectacle — for a lack of grit.

The oldest team the Americans have ever brought to the Games has endured plenty through the years, from health scares to losses in their personal life. Those experiences have prepared them for whatever may come, perhaps Biles most of all.

So when the most decorated gymnast of all time felt a tweak during her floor exercise warm-up on Sunday, she didn’t panic. Neither did her teammates.

Biles briefly retreated to the back so coach Laurent Landi could essentially mummify the bottom of her left leg, then came back out and helped fuel a team that looks every bit as good as advertised.

With Biles — achy calf and all — putting up the highest score on both the vault and floor exercise, and reigning Olympic champion Sunisa Lee looking perhaps as good as ever on uneven bars, the United States posted a total of 172.296, doing little to dampen the expectation that Tuesday night’s team final will be more of a coronation for a team that has called this trip to the Games part of their “Redemption Era.”

“They’re happy and relieved,” U.S. coach Cecile Landi said. “Day one, now moving on to team finals, all-around finals, a couple event finals hopefully.”

Men’s basketball

The U.S. men’s basketball team improved to 56-0 when scoring more than 100 points.

LeBron James and Kevin Durant were a combined 18 for 22 from the field in the 110-84 win over Serbia in the Olympic opener for both teams.

“That’s the best game we’ve played so far,” James said after the Americans improved to 6-0 this summer, 1-0 in the tournament that matters. “Whatever it takes. It’s going to be somebody different every day. And we have that type of firepower.”

The U.S. improved to 144-6 overall in Olympic play.

Durant made his first eight shots on the way to 23 points in less than 17 minutes, James added 21 points, nine assists and seven rebounds and the U.S. rolled to a 110-84 win over Serbia in the Olympic opener for both teams.

Men’s tennis

Rafael Nadal is off to a winning start in singles play at the Olympics, beating Marton Fucscovics in three sets.

Nadal, who broke Fucscovics to go up 3-2 in the third set before having part of his right ring finger taped up, finished off his opponent to win 6-1, 4-6, 6-4.

The victory sets up a blockbuster showdown against rival Novak Djokovic in the second round at Roland Garros, where Nadal has won the French Open a record 14 times.

Women’s rugby

Defending champion New Zealand and 2016 gold medalist Australia dominated their groups on the opening day of the Olympic women’s rugby sevens competition at Stade de France. The top four ranked teams all finished Sunday on two wins apiece, with the United States and France also unbeaten ahead of their Pool C showdown on Day 2. Ilona Maher has already produced a moment for the U.S. team that personified the posts she sends on social media about strong, athletic women.

And Raquel Kochhann got to play at her third Olympics for Brazil just six months after returning from a lengthy break from competitive rugby while she recovered from breast cancer and treatment.

Women’s soccer

Sophia Smith scored a pair of goals to help the United States beat Germany 4-1 and advance to the quarterfinals at the Paris Olympics. Mallory Swanson and Lynn Williams also scored for the Americans who defeated Zambia 3-0 in the opener.

Australia produced a stunning comeback to beat Zambia 6-5 in Nice and boost its chances of advancing to the quarterfinals the tournament. Momoko Tanikawa scored deep in stoppage time to clinch Japan’s 2-1 comeback win over Brazil. World champion Spain beat Nigeria 1-0 to make it two wins from two in Group C. Colombia beat New Zealand 2-0 in Lyon.

Women’s swimming

Torri Huske thought she might have finally won her first Olympic gold but couldn’t yet be sure. Her American teammate and reigning world-record holder Gretchen Walsh swam to her right and they were millimeters apart over the fantastic finish in the 100-meter butterfly. Huske caught Walsh this time, something she couldn’t do at the Olympic trials last month. Husked finished just .04 seconds ahead of Walsh in a captivating 1-2 U.S. finish ahead of Chinese bronze medalist Zhang Yufei.
