The Latest: Uzbek boxer Dusmatov wins light flyweight gold
RIO DE JANEIRO (AP) The Latest on the Olympics in Rio de Janeiro (all times local):
The lone Russian track and field athlete at the Olympics has won her appeal to compete at the Rio de Janeiro Games.
The Court of Arbitration for Sport ruled early Monday morning that long jumper Darya Klishina is eligible to take part in Tuesday's qualifying.
Klishina was the only one of 68 Russians cleared to participate in Rio by the IAAF, largely because she has been based outside Russia for the past three years.
But the sport's governing body banned her from the Olympics last week after receiving what it said was new information.
CAS ruled that Klishina was eligible to compete because she fulfilled the requirements set by the IAAF.
The long jump final is scheduled for Wednesday.
Kerri Walsh Jennings and April Ross are in the Olympic beach volleyball semifinals.
They'll play defending world champions Agatha and Barbara on the Brazilians' home sand to clinch a medal.
The Americans beat Australia 21-14, 21-16 on Sunday night to advance.
Walsh Jennings is going for her fourth straight Olympic gold medal, and Ross won silver in London in 2012.
Walsh turned 38 at midnight, and the U.S. fans serenaded her with ''Happy Birthday'' during the match.
Usain Bolt and Justin Gatlin are not thrilled with the schedulers who put only an hour between the semifinals and the finals of the men's 100-meters.
Gatlin says there wasn't enough turnaround time and he had only 30 minutes to prepare.
Bolt was far more outspoken and blamed the scheduling on a slower pace for the entire field.
He called the short gap ''ridiculous'' and had thought he could run faster than he did because he felt so strong in the semifinals.
Bolt won the Sunday night final - his third consecutive gold medal in the 100 meters. Gatlin took silver.
Usain Bolt expected an easier race to the men's 100-meter title than in years past.
Why? The Jamaican said he's in far better shape than he was a year ago, when his races were ''pretty much a dog fight.''
Bolt won his third consecutive gold medal in the 100 meters on Sunday night and already has his sights set on the 200-meters and possibly a new world record. He said he's far more confident about the 200 than he is the 100, and having a day of rest this week will make him fresh for his next event.
Bolt reiterated that these Olympics are for one purpose: For him to prove he's the greatest sprinter ever.
Brazil now has half of the women's beach volleyball semifinalists.
World champions Agatha and Barbara advanced with a 23-21, 21-16 victory over Russia on Sunday night. That lined them up for a matchup with the winner of the midnight match between Australia and Americans Kerri Walsh Jennings and April Ross.
Brazil's Talita and Larissa, the No. 1 seed, advanced earlier Sunday with a victory over Switzerland.
The hosts also have one men's team still playing. Alison and Bruno will face Americans Phil Dalhausser and Nick Lucena on Monday.
Justin Gatlin is satisfied with second place in the 100-meter finals.
At 34, Gatlin was the oldest sprinter in the field and he took solace in medaling.
Gatlin was booed when he was introduced at the introductions because of his doping suspensions, but Gatlin said he tuned out the reaction on Sunday night and focused on the American flags in the crowd.
Told later that winner Usain Bolt was upset Gatlin was booed, the American said he has tremendous respect for Bolt.
Gatlin said: ''There is no bad blood. I'm a competitor, he's a competitor and he has pushed me to be the athlete that I am today. I hope he can say the say for me.''
It's hard to get a wave started at the Copacabana beach volleyball venue, even when you're an NBA star like DeAndre Jordan.
Jordan and fellow U.S. basketball players Kevin Durant and Jimmy Butler showed up to see the women's beach quarterfinals on Sunday night and immediately caused a stir. Jordan tried to get the crowd going, but the Brazilian fans were too distracted watching world champions Agatha and Barbara against Russia.
Durant put on a USA Volleyball scarf, and they all mugged for pictures as they waited for Americans Kerri Walsh Jennings and April Ross to begin their match.
Durant also saw Walsh Jennings play in London, when she won her third straight Olympic gold medal.
Yohan Blake failed to medal in the men's 100-meters but paid tribute to Jamaican teammate Usain Bolt.
Blake finished fourth and called Bolt ''an icon and true warrior of the sport.''
There was a time when Blake was considered one of the few sprinters who could dethrone Bolt and he took the silver in London four years ago.
He said injures have slowed him, but insisted ''I'm not dead'' and he'll be back.
He praised Bolt for his long reign. When asked if Bolt is bigger in Jamaica than Bob Marley, Blake said ''he's getting there.''
As Wayde van Niekerk sprinted to a world record in winning the men's 400-meters, his competitors could only watch in awe.
Third-place finisher LaShawn Merritt said van Niekerk took off at the start and set a far faster pace than he thought would win the race.
Silver medalist Kirani James of Grenada marveled that van Niekerk never slowed. He was trying to use van Niekerk as a gauge, but the winner ''just kept going.''
Minutes after winning Olympic gold, Usain Bolt unlaced his now-famous gold spikes and took selfies with fans in the near-capacity stadium in Rio de Janeiro.
Then, he turned his yellow hat backward, kneeled down and gave the crowd what it really wanted: The arching ''To the World Pose.''
The Jamaican superstar won the signature event in track and field on Sunday night added this race to his already gleaming resume as the first person to capture three straight 100-meter titles at the Olympics.
Bolt beat American Justin Gatlin, who was greeted by the fans with raucous boos, by .08 seconds. Andre de Grasse of Canada won the bronze.
Usain Bolt became the first person to win three straight Olympic 100-meter titles, blowing down the straightaway in 9.81 seconds for his seventh overall Olympic gold.
American Justin Gatlin, Bolt's closest pursuer over the past four years, finished second, .08 seconds behind. Andre de Grasse of Canada won the bronze.
Bolt came into the Olympics not having run a 100 since June 30, when he pulled out of Jamaican national championships with a bad left hamstring.
The rehab began immediately, and on a muggy Sunday night in Rio, the shining star of track and field showed no signs of distress.
After a typically clunky burst out of the starting block, he started pulling away from Gatlin with about 30 meters left.
He's not done. Qualifying for the men's 200, his favorite race, starts Tuesday, with the relay on Friday.
MEDAL ALERT: Usain Bolt wins unprecedented third Olympic gold in 100 meters, defeating Justin Gatlin of the US by .08 seconds.
Florian Fuchs scored with no time remaining on the clock, and two-time defending Olympic champion Germany scored twice in the final minute to beat New Zealand 3-2 Sunday in the men's field hockey quarterfinals.
Germany trailed 2-0 before scoring all three of its goals in the final five minutes. Moritz Furste scored on a penalty corner at 55:29, then scored on another penalty corner with 41 seconds remaining.
New Zealand went ahead 1-0 on a goal by Hugo Inglis early in the second period, and increased its lead to 2-0 on a goal by Shea McAleese early in the fourth.
Germany advanced to play Argentina, which defeated Spain 2-1 earlier in the day.
MEDAL ALERT: Caterine Ibarguen of Colombia has won the triple jump at the Rio Games, with a jump of 15.17 meters on her fourth attempt to win the gold. Yulimar Rochas of Venezuela took silver with 14.98 and defending champion Olga Rypakova of Kazakhstan settled for bronze with 14.74.
Wayde van Niekerk has won the Olympic 400-meter title in a world-record 43.03 seconds, lowering the mark set by Michael Johnson in 1999.
And the South African did it from the outside lane. Van Niekerk stormed out of the blocks and kept going, holding off 2012 Olympic champion Kirani James and 2008 winner LaShawn Merritt, who both ran season-best times to finish with silver and bronze.
Johnson set the previous world record of 43.18 at Seville, Spain, in 1999.
Van Niekerk's previous personal record was 43.48.
MEDAL ALERT-WORLD RECORD: Wayde van Niekerk of South Africa has won the Olympic 400-meter title in a world record 43.03 seconds. Van Niekerk, running in the outside lane, stormed out of the blocks and held off of 2012 champion Kirani James and LaShawn Merritt. He lowered the mark of 43.18 that Michael Johnson set in Seville, Spain, in 1999.
Andrew Fisher saw his chances at making the men's 100-meter final dashed when he false started in the semifinals.
The sprinter representing Bahrain blamed a hovering helicopter.
Fisher said the helicopter approached Olympic Stadium as he was in the starting block and it distracted him. He knew instantly he was disqualified.
He said it's the first false start of his international career.
Fisher said ''it was the chopper,'' and ''that should never happen at a meet this big.''
The coach of long jumper Darya Klishina, the only Russian entered in Olympic track and field, tells the Associated Press she is trying to block out the uncertainty over whether she can compete.
Klishina was at a Court of Arbitration for Sport hearing earlier Sunday as she fights to stay in the Olympics.
When the Russian team barred due to doping scandals, the IAAF gave Klishina an exemption it then withdrew citing ''new information''. Klishina's lawyer says that concerns possible tampering with doping samples by Russian authorities.
Coach Loren Seagrave says their plan is to ''act as if'' Klishina can compete and ''we don't yet know the outcome so we must look at the situation in the positive.''
Klishina trained at a warmup track near the Olympic Stadium on Sunday.
Usain Bolt and Justin Gatlin set up the biggest clash on the Olympic track by both winning their 100 meters semifinals.
Bolt was slow out of the blocks again but powered through the midsection before easing across the line in a season's best of 9.86. He had time to look left and right before turning the power off, showing off the smile the world has come to love. Andre de Grasse of Canada finished in 9.92 to go through.
Gatlin was all business, fast from the start and barely letting up at the finish for a time of 9.94. After being roundly booed by the crowd before the start, he immediately disappeared into the stadium tunnel after his win.
Jimmy Vicaut of France won the first heat in 9.95, turning around a disappointing season with a place in the final.
Jamaican Nickel Ashmeade was out, finishing fifth in the first heat with a time of 10.05.
World champion Allyson Felix ran a season-best 49.67 to lead the qualifiers into the women's 400-meter final.
Felix is running only in the 400 after missing a chance to defend her Olympic 200-meter title by failing to make the U.S. team. She went out hard and coasted to the finish ahead of Shaunae Miller, the world championship silver medalist of Bahamas.
There'll be three Americans and two Jamaicans in Monday's final.
Phyllis Francis of the United States won the first of the three semifinal heats in 50.31, holding off Stephenie Ann McPherson of Jamaica.
World championships bronze medalist Shericka Jackson set a personal best 49.83 to win the second heat, overhauling American Natasha Hastings on the line.
Christine Ohuruogu, the 2008 Olympic champion and silver medalist in London in 2012, was knocked out after finishing fifth in the first heat.
