Each day of the Tokyo Games, NBC Olympics will provide a roundup of news from a variety of sports. Catch up here on all the storylines and must-see highlights you may have missed while you were sleeping.

The United States’ medal drought lasted only one day, as former Georgia teammates and longtime training partners Chase Kalisz and Jay Litherland finished 1-2 in the 400-meter individual medley.

Elsewhere, as expected, a young American won gold in another sport beginning with “s.” But it was in shooting, not skateboarding. 

And fencing. And taekwondo.

Like skateboarding, surfing made its Olympic debut Sunday in Tokyo, and the U.S. athletes impressed.

Men’s 400-meter individual medley: Kalisz led through much of the race and won by a comfortable margin of 0.86 seconds. Litherland spent most of the race in fourth place but flew down the last 50 meters in 27.96 seconds to edge out Australian Brendon Smith.

Medal results: 

Gold: Chase Kalisz (USA)

Silver: Jay Litherland (USA)

Bronze: Brendon Smith (AUS)

Women’s 400 individual medley: Japan’s Ohashi Yui and American Emma Weyant spent the last half of the race in first and second with few challengers. Behind them, Hali Flickinger chased down Hungarian legend Katinka Hosszu, who wound up fading to fifth.

Medal results:

Gold: Ohashi Yui (JPN)

Silver: Emma Weyant (USA)

Bronze: Hali Flickinger (USA)

Women’s 4x100 freestyle relay: Australia took down the world record with a time of 3:29.69, more than three seconds ahead of the rest, but the more surprising finish in the overall pecking order of international swimming may be Canada taking silver by 0.03 seconds ahead of the U.S. team. Still, the United States kept alive its streak of winning a medal in every Olympics it has contested since 1912. Simone Manuel took the anchor leg after Erika Brown, Abbie Weitzeil and Natalie Hinds. It’s also a 10th career medal for Allison Schmitt, who was in the prelims with Catie DeLoof and Olivia Smoliga.

Medal results:

Gold: Australia

Silver: Canada

Bronze: USA

Men’s 400 freestyle: A stunner! Tunisian teenager Ahmed Hafnaoui won his country’s first Olympic medal in the event, surprising an accomplished group of swimmers from Lane Eight and leaping into an exultant celebration. U.S. swimmer Kieran Smith barely untouched a gaggle of swimmers for bronze. 

Medal results

Gold: Ahmed Hafnaoui (TUN)

Silver: Jack McLoughlin (AUS)

Bronze: Kieran Smith (USA)

It was an off night for the U.S. women. The ROC outscored them 171.629 to 170.562.

It might not matter.

Simone Biles posted the top all-around score, as usual, and she qualified for every event final. Sunisa Lee, as expected, took the second all-around spot.

Less expected was that Jade Carey, who qualified for the Olympics on her own as an event specialist and did not count her scores toward the team tally, would post the third-best U.S. all-around score. Mykayla Skinner, also competing as an event specialist, also finished ahead of the other two gymnasts whose scores counted for the U.S., Jordan Chiles and Grace McCallum.

Still, the team wound up hitting its maximum of two entries in each eight-gymnast final, with Biles going to all four, Lee going on uneven bars and balance beam, and Carey going on vault and floor exercise. The limit of two per country helped the U.S. in the uneven bars, where Biles finished 10th but will go ahead of the third and fourth ROC gymnasts, and hurt in vault, where Skinner placed fourth.

The women's team final is set for Tuesday evening Japan time.

The U.S. men's epic win streak at the Olympics crashed to a halt as the team went ice-cold down the stretch and lost to France. The team will have plenty of time to regroup in the rest of the group stage against the Czech Republic and Iran.

Final scores

Czech Republic 84, Iran 78

Italy 92, Germany 82

Australia 84, Nigeria 67

France 83, United States 76

Horigome Yuto saved his best tricks for last in the first-ever skateboarding competition, winning the men’s street competition in the city in which he grew up. Jagger Eaton took bronze for the U.S., while favorite Nyjah Huston slipped a couple of times after going big with his second run.

Medal results

Gold: Horigome Yuto (JPN)

Silver: Kelvin Hoefler (BRA)

Bronze: Jagger Eaton (USA)  

 

Like Ginny Thrasher in Rio, 20-year-old collegian Will Shaner surprised everyone with an air rifle gold medal. Shaner took a comfortable lead after 10 shots and never came close to relinquishing it. 

Medal results

Gold: Will Shaner (USA)

Silver: Sheng Lihao (CHN)

Bronze: Yang Haoran (CHN)

Teenager Caroline Marks and highly regarded veteran Carissa Moore earned free passes to the third round as surfing made its Olympic debut. 

Kolohe Andino also went straight to Round 3, while John John Florence made it to Round 2.

The U.S. team escaped against traditional rival Australia, which took the game to an extra inning and grabbed a 1-0 lead on some uncharacteristic wildness from Monica Abbott. But Amanda Chidester kept the Americans unbeaten with a two-run walk-off single.

Japan also remained unbeaten with an extra-inning win in a strange game that saw Canada briefly walk off the field to protest an umpire's decision.

Final scores

United States 2, Australia 1 (8 innings)

Japan 1, Canada 0 (8 innings)

Mexico 5, Italy 0

 

TAEKWONDO 

American 18-year-old Anastasija Zolotic became the first U.S. woman to win gold in a taekwondo event and did so with a series of dominating scores:11-4, 17-9, 28-5 and 25-17. Upsets abounded, with Iranian-born refugee competitor Kimia Alizadeh defeating two-time gold medalist Jade Jones of Great Britain and top men's seed Lee Dae-Hoon of South Korea giving up a big lead and losing in the Round of 16 to eventual champion Ulegbek Rashitov.

Medal results, women’s 57kg

Foil fencer Lee Kiefer has been knocking on the door of Olympic success for a while, taking fifth in London and 10th in Rio. On Sunday, she nearly bowed out in the Round of 16 against Canadian Eleanor Harvey, falling behind 8-4 in a fight to 15 points. Even after struggling back to 10-10, she gave up the next two hits. A deadlock at 12-12 seemed to last an eternity, and Harvey scored once again to move two hits from victory. Kiefer responded with three straight to advance.

Her next two bouts were, strangely for an elimination tournament, progressively easier. She beat Japan's Ueno Yuka 15-11 despite giving up three straight hits at 14-8. She virtually ran the ROC's Larisa Korobeynikova off the piste, scoring seven straight points to go up 8-1 and cruising to a 15-6 win to seal at least a silver medal.

The gold medal bout against another Russian, Inna Deriglazova, was almost as difficult as the bout against Harvey, but Kiefer never trailed en route to a 15-13 win and the first gold for the U.S. fencers in Tokyo.

Medal results, women's foil

Gold: Lee Kiefer (USA) 

Silver: Inna Deriglazova (ROC)
