RIO DE JANEIRO (AP) -- The Latest on the 2016 Summer Olympics in Rio de Janeiro (all times local):
Brazil has won its second gold of the Rio Games when 22-year-old Thiago Braz da Silva upset Olympic champion Renaud Lavillenie.
Lavillenie, of France, first set the Olympic record at 5.98 meters, and boosted by the boisterous home fans, da Silva cleared 6.03 to improve on that mark.
Sam Kendricks of the United States took bronze with 5.85.
Italy's Paolo Nicolai and Daniele Lupo have beaten one of Russia's two men's beach volleyball quarterfinalists and moved one win away from an Olympic medal.
The Italians won 21-18, 20-22, 15-11 on Monday night, playing an hour or so after a downpour drenched the Copacabana venue. After the winning point hit the wet sand, Nicolai doubled over, his head in his hands, and his partner gave him a hug, trying to lift him.
Russians Dmitri Barsouk and Nikita Liamin were the No. 23 seed in the tournament. Another Russian team, Viacheslav Krasilnikov and Konstantin Semenov, were to play Cuba later Monday night.
Dubbed the "world select" team, Qatar is advancing in men's handball.
The gas-rich Middle Eastern nation of Qatar fields a squad composed almost entirely of foreign-born players from around the globe, provoking controversy among opponents.
Despite second place at last year's world championships, they left it late to qualify for the Olympic quarterfinals, needing a 22-18 win over Argentina on Monday night to make it through.
Qatar's reward for qualifying is a tough game against reigning European champion Germany on Wednesday.
The women's quarterfinals are Tuesday, with hosts Brazil playing 2015 world silver medalist the Netherlands, while reigning Olympic and world champion Norway meets Sweden in an all-Scandinavian clash.
MEDAL ALERT-UPSET ALERT: Brazil's Thiago Braz da Silva broke the 6-meter barrier to upset defending champion Renaud Lavillenie and win pole vault gold with an Olympic record of 6.03. Lavillenie, of France, took silver with 5.98 and American Sam Kendricks had bronze with 5.85.
It took a dramatic dive by Shaunae Miller of Bahamas at the finish line to win the women's 400-meter final, preventing American Allyson Felix from capturing a record fifth Olympic gold medal.
Miller clocked 49.44 seconds, running in lane 7, to narrowly hold off Felix, who finished in 49.51. Shericka Jackson of Jamaica won the bronze in 49.85.
Felix won the 400 at the world championships last year and was planning to run the 200- and 400-meter double in Rio, but was hampered by an ankle injury at the U.S. trials and didn't make the team for the 200. She won the 200 in London four years ago.
Felix now has seven Olympic medals, including three silvers. She could still run both the 4x100 and the 4x400 relays in Rio.
The 30-year-old American entered the games as one of six women with four Olympic gold medals in track and field.
MEDAL ALERT: Shaunae Miller of Bahamas has won the women's 400-meter final with a diving finish, preventing American Allyson Felix from capturing a fifth Olympic gold medal. Miller finished in 49.44 on Monday to narrowly hold off world champion Felix, who finished strongly in 49.51. Shericka Jackson of Jamaica won the bronze in 49.85.
Middle distance runner David Rudisha won gold -- but didn't get a world record this time.
The Kenyan won his second Olympic title in a row on Monday by swerving into the lead just after halfway and using his long strides to kick for home.
The only one to keep close was Taoufik Makhloufi, the 1,500 gold medalist at the London Games four years ago.
Between the two middle distance champions, Rudisha never gave the Algerian a chance and won in 1 minute, 42.15 seconds, over a second of the time he set at the Olympics four years ago.
Makhloufi ran an Algerian record of 1:42.61 and Clayton Murphy of the United States set a personal best of 1:42.93 for bronze.
MEDAL ALERT: David Rudisha of Kenya has won his second 800-meter Olympic title in a row with a devastating last lap, beating Taoufik Makhloufi of Algeria. Clayton Murphy of the United States took bronze. This time, there was no world record, but his time of 1 minute 42.15 was his season's best.
Usain Bolt received his latest gold and Justin Gatlin picked up his latest silver -- this time, without any fuss.
A night after Bolt won his third Olympic title at 100 meters, beating Gatlin, the medalists returned to the Rio Games track for the ceremony.
Gatlin smiled widely as his name was announced Monday, then blew a kiss to polite applause. No sign of the full-throated booing that accompanied his introduction before Sunday's sprint.
Gatlin has become a polarizing figure in the sport after serving two doping bans.
A year ago at the world championships in Beijing, Gatlin also finished second to Bolt in the 100.
When the American stood on the podium there, he pointed a finger and shouted at someone in the stands who was bothering his mother.
Rain that caused a 25-minute disruption to the Olympic track and field program has caused havoc on the 110-meter hurdles and the discus preliminaries.
In the hurdles, the first four in each of the five heats automatically advance to the semifinals, along with the next four fastest times.
Organizers announced that the eight hurdlers who didn't qualify automatically from the two rain-affected heats before the rain delay would get another chance in a special race at the end of Monday night's schedule to push for a qualifying time.
The discus throwers were having difficulty in the slippery conditions, with nine of the 17 competitors fouling on their first attempt, and six on the second.
China leads the standings after men's 3-meter springboard preliminaries.
Cao Yuan totaled 498.70 points on Monday as he seeks to add another medal at the Rio Games. Cao won bronze in synchronized 3-meter.
Rommel Pacheco of Mexico was second at 488.25, followed by Kristian Ipsen of the United States at 461.35.
Others advancing to the semifinals include Patrick Hausding of Germany, Jack Laugher of Britain and American Mike Hixon. Laugher earned gold in synchro 3-meter.
Defending champion Ilia Zakharov of Russia barely scraped into the semis, grabbing the 18th and last spot.
The International Cycling Union says it will check Tuesday to see if a wildfire has impacted the mountain bike course for the Rio Olympics.
Ash from a wildfire roughly 10 miles from the Olympic field hockey venue littered the playing surface before the Monday evening session of the women's quarterfinals in that sport.
The mountain bike center is about 2 miles from the field hockey venue.
The UCI says it is has been told that the fire is under control.
Practice on the mountain bike course begins Wednesday. The women's race will be held Saturday, with the men's race on Sunday.
