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.
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.
Gold: Chase Kalisz (USA)
Silver: Jay Litherland (USA)
Bronze: Brendon Smith (AUS)

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.
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.
Gold: Ahmed Hafnaoui (TUN)
Silver: Jack McLoughlin (AUS)
Bronze: Kieran Smith (USA)

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.
