Well, China does indeed pick up two gold medals: they only win one of the two they were expected to get, but they pull off a mild upset on the track, winning the women's javelin.
Meanwhile, USA comes up short on the track, yet again, finishing 0-for-3 in events where they were at least expected to have a chance to win gold: the US women's relay team finished in second, to Jamaica, Paul Chelimo settled for bronze in the men's 5000m, and Maggie Malone, who was second in qualifying for the women's javelin, finished in tenth.
There was one feel-good story on the track, though: Allyson Felix, at the age of thirty-five, earned her tenth career Olympic medal, becoming the most decorated women's track runner in Olympic history, and tying fellow American Carl Lewis for most medals won on the track. She has announced that she intends to retire before Paris in 2024, but is expected to be a part of the women's 4x400m relay team, in what would then be her final Olympic race. Also, Gable Steveson took care of business on the mat, as expected. And, as previously mentioned, Ross and Klineman won gold in beach volleyball, allowing USA to keep pace with China.
USA still has some team events that we can (usually) rely on but, barring a few surprises, it looks like this will be the first time the US finishes without the most gold medals at a Summer Games, since Beijing.
