Top shots from the Rio Olympics
Renaud Lavillenie went jump-for-jump with Thiago Braz da Silva.
But it was the Brazilian who won the day, wresting the gold medal from the former Olympic champion after a thrilling jump-for-jump final on Monday night. Da Silva set an Olympic record when he cleared the bar at 6.03 metres. Lavillenie and American Sam Kendricks won the silver and bronze medals with heights of 5.98 and 5.85, respectively.
For Lavillenie, this…
Turned to this.
Canadian Shawn Barber bowed out after missing three times at 5.65 metres.
Rain delayed the pole vault, but not this hurdles race.
The 110-metre men's hurdles qualifier went ahead despite a downpour. Canadian Johnathan Cabral qualified for the semifinals. This is German Matthias Buhler and Milan Trajkovic of Cyprus racing in the rain.
Shaunae Miller dove across the line in the 400-m hurdles.
The Bahamian sprinter dipped, then dove on a wet track to break the timing plane at the finish of the women's 400-metre hurdles, upsetting American Allyson Felix to win the race and a gold medal.
Earlier on the track, Nercely Soto of Venezuela (pictured) qualified for the 200-metre semifinal, as did Crystal Emmanuel of Canada.
Simone Biles bobbled on the beam.
The teenager came to Rio with five gold medals in her sights but a slight stumble on the balance beam was enough to bump her into the bronze medal position on Monday. Biles already has two golds in her Olympic debut and has a shot at another in the floor routine Tuesday.
Canadian Isabel Onyshko had a fall on the beam and landed in eighth place.
North Korea's Ri Se-Gwang won the gold in men's vault.
That blur in the middle is cyclist Allison Beveridge.
The Calgarian had a rough opening day in the track cycling women's omnium after crashing with German rider Anna Knauer. Both were OK and the Canadian went on to finish the day in 13th place after three events.
Here's another from the track, because speed blur looks amazing.
Australia played Hungary in a water polo quarter-final match.
The Australians lost 11-13. Hungary will play water polo powerhouse Montenegro on Tuesday with the Aussies facing Brazil a day later.
It got too windy for sailing on Monday.
This is Yannick Brauchli and Romuald Hausser of Switzerland in action before their 470 class race was postponed on account of too-strong winds at Marina da Gloria.
The women's 10-km marathon swim got dicey at the end.
Dutch swimmer Sharon van Rouwendaal won in convincing fashion but it was the disqualification of 2015 world champion Aurelie Muller of France that made headlines.
The 26-year-old, who would have won the silver medal, was ejected from the race because officials say she impeded third-place finisher Rachele Bruni of Italy near the finish. Here's Muller earlier in the distance race.
It was a disappointing Monday for Canadian paddlers.
All four Canadian canoe and kayak teams competing Monday moved on to the semifinals in their respective events, but all four failed to qualify for the medal round in those races. Olympic veteran Adam van Koeverden missed a stroke in the K-1 1,000-metre kayak race and never recovered. He'll race Tuesday in the B final, out of the medals.
This is Jess Walker of Great Britain sprinting to the finish in the women's 200-metre kayak singles semifinal on Monday.
