The Latest: Manuel all business in prelims a day after gold
RIO DE JANEIRO (AP) The Latest on the Olympics being held in Rio de Janeiro (all times local):
On the day after winning an Olympic gold, Simone Manuel of the United States was back in the pool for the 50-meter freestyle.
Manuel was all business as she advanced out of the preliminaries Friday with the 11th-fastest time of 24.71 seconds.
Pernille Blume of Denmark was the top qualifier in 24.23. Also advancing were sisters Cate and Bronte Campbell of Australia, defending Olympic champion Ranomi Kromowidjojo of the Netherlands, American Abbey Weitzeil, and 39-year-old Therese Alshammar of Sweden.
Manuel became the first African-American woman to capture a gold medal with a victory in the 100 freestyle. She shared the title with 16-year-old Canadian Penny Oleksiak, who was not entered in the 50 free.
China's Chen Xinyi withdrew after testing positive for a banned substance.
Andy Murray has rallied from down a break in the final set for the second straight day to keep alive his chances of becoming the first tennis player to win back-to-back Olympic singles gold medals.
The heavy favorite after top-ranked Novak Djokovic lost in the first round, Murray beat 22nd-ranked American Steve Johnson 6-0, 4-6, 7-6 (2) in the quarterfinals Friday. It was eerily similar to his match Thursday against second-seeded Fabio Fognini, who dominated the first set only to drop the second and go down a break in the third.
Johnson was two games from victory, serving at 4-3 in the final set, but Murray broke back then saved a break point in the next game. He jumped out to a 4-1 lead in the third-set tiebreaker on the way to clinching a spot in the medal rounds.
Australian center Andrew Bogut is not playing in a preliminary round game against China.
Bogut, who recently returned to action after injuring his left knee in the NBA Finals, was not on the bench as the Aussies took on a team they were expected to easily handle.
There was no immediate word from the Australian team on Bogut, who sat on the bench and cheered on his teammates. The 31-year-old's presence has been a big reason why the Aussies are in contention to win their first medal in men's Olympic basketball.
Australia gave the U.S. all it could handle in its previous game, losing 98-88 to the Americans.
Bogut signed as a free agent with Dallas this summer after four seasons with Golden State. He was selected by Milwaukee with the No. 1 overall pick in the 2005 draft.
After a delay of nearly two hours due to lack of wind, boats are heading out onto Guanabara Bay for the sailing regatta.
There was wind in the morning when it was raining, but the breeze faded at midday. Races were supposed to start at 1:15 p.m., but most classes stayed ashore due to lack of wind.
Race officials made the decision to launch the men's and women's windsurfers from the Marina da Gloria rather than the Flamengo Beach ramp because pre-games research indicated that when it rains, the runoff can sometimes impact the water quality near the launch area. Also, some coaches had expressed concern about the size of the waves near the Flamengo Beach ramp.
The wild 49er class is scheduled to begin Friday, as well as the new women's 49erFX.
The big showdown in the 49er is going to be between defending gold medalists Nathan Outteridge and Iain Jensen of Australia, and defending silver medalists Peter Burling and Blair Tuke of New Zealand.
Tennis player Monica Puig is one victory away from Puerto Rico's first gold medal in Olympic history.
Puig continued her surprising run at the Rio Games by reaching the women's singles final, eliminating two-time Wimbledon champion Petra Kvitova of the Czech Republic 6-4, 1-6, 6-3 on Friday.
Puig is ranked 34th and unseeded, but her win over No. 11 seed Kvitova follows victories against No. 3 Garbine Mguruza and No. 14 Anastasia Pavlyuchenkova.
Puig is guaranteed to leave Brazil with no worse than a silver. She faces Angelique Kerber of Germany or Madison Keys of the U.S. in Saturday's final.
Puerto Rico has won two silvers and six bronzes at past Olympics.
Kvitova will meet the loser of Kerber vs. Keys to decide the bronze.
This was supposed to be the big heptathlon battle between British defending champion Jessica Ennis-Hill and her closest rival Brianne Theisen-Eaton. After two of seven events they are just battling to get to the top.
Instead of the two athletes who dominated last year's world championships, it is Ennis-Hill's compatriot Katarina Johnson-Thompson leading, just ahead of Belgian Nafissatou Thiam. Both scaled 1.98 meters in the high jump, bettering by 1 centimeter the best-ever mark in a heptathlon competition.
First-event leader Ennis-Hill got stuck at 1.89, again off her top mark of 1.95. Theisen-Eaton had 1.86.
Johnson-Thompson leads with 2,264 points, edging Thiam by 12points. Ennis-Hill has 2242 for third place and Theisen-Eaton is currently fifth with 2151.
The shot put and 200 are set for later Friday.
Step one is done for Brazil in women's handball.
With standout player Ana Paula Rodrigues top-scoring for the third time in four games, Brazil secured a place in the playoffs with one game of the group stage remaining Friday.
Rodrigues scored seven goals in Friday's 28-24 win over Angola, while eight other Brazilians contributed goals in a strong team performance.
That leaves Brazil, which has benefited from passionate home support, with six points in Group A and assured of a place in Tuesday's quarterfinals.
Brazil has also beaten reigning Olympic champion Norway and Romania, but lost a chance for a perfect record with Wednesday's 29-24 loss to Spain.
Four-time Olympian Ana Paula thinks she understands why the crowds have been so supportive at the Copacabana volleyball venue during the Olympics: It's because Brazilians care more about volleyball now than even soccer.
That's like an American saying he prefers field hockey to football.
Ana Paula, who is working the Rio Games as part of the venue entertainment crew, played volleyball at four Olympics, two indoor and two beach. She won a bronze medal with the Brazilian indoor team in Atlanta.
She says: ''Some people hammer me for this statement, but I don't think Brazil is a soccer country anymore.''
Brazil has turned out for beach volleyball in Rio, and the teams have responded. All four Brazilian teams made it into the knockout stage, and top women's team Agatha and Barbara beat China on Friday to reach the quarterfinals.
In the other morning match, the Russian men beat Qatar.
The United States and Sweden were scoreless at the half in an Olympic women's soccer quarterfinal match on Friday in Brasilia. The Americans had several chances but couldn't get past goalkeeper Hedvig Lindahl.
U.S. goalkeeper Hope Solo punched a corner kick away in the 43rd minute.
The crowd at Mane Garrincha Stadium in was sparse at the start of the match and never extended much past the lower bowl of the massive 72,000-seat stadium that was expanded for the men's 2014 World Cup.
The fans that were there continued to jeer Solo with shouts of ''Zika!'' every time she touched the ball. She's been taunted since the opening match in Brazil because of her posts on social media about the virus.
Olympic organizers say a taxi carrying two members of the German delegation was involved in a serious accident in Rio de Janeiro and one of them was hospitalized.
Rio games spokesman Mario Andrada says the two people, including a canoe slalom coach, were coming back to the athletes' village when the taxi was involved in an accident.
Andrada added that ''preliminary reports say there was a serious accident'' with one of the passengers taken to hospital.
British gold medalists Helen Glover and Heather Stanning praised their rowing coach Robin Williams for his commitment to their quest for an Olympic double in the women's pair despite his battle with cancer.
Glover says Williams ''had a really bad illness in this Olympiad and you wouldn't know it.'' She says he was up cycling and coaching when he should have been in bed.
Williams, a former competitive rower, started coaching Glover and Stanning in 2010. Besides gold in London and Rio, the pair won world championship titles in 2014 and 2015.
Stanning says the team wouldn't be who they are without Williams.
Glover dubs him the ''third member of the pair.''
An official says practice at the Olympic diving pool was canceled in order to keep the water still so the now-green pool would return to its blue color.
But Simon Langford, media venue manager at Maria Lenk Aquatics Centre, says training has resumed and preliminaries of women's 3-meter springboard will go on as scheduled later Friday.
The pool remained green early Friday afternoon.
Langford says the decision to cancel practice was supported by FINA, the sport's world governing body.
Some divers have complained they were not given advance notice of the pool's closure.
The diving pool's water turned a murky green earlier in the week midway through the synchronized events. The unusual color later spread to the water polo pool next to the diving pool, although it wasn't as pronounced.
The Olympic diving pool has reopened for practice after it was closed for cleaning.
Some divers say they arrived Friday morning only to find out the pool with murky green water was closed.
Now divers are plunging off the boards ahead of the women's 3-meter springboard, which begins later in the day.
Russia will face France in Friday night's men's team foil finals after rallying to beat the U.S. 45-41.
The Americans went into the final match of the nine-bout semifinals ahead 40-39 and with top-ranked Alexander Massialas set up as the closer.
But Massialas was routed by Alexey Cheremisinov, who scored six quick touches to send the Russians through.
The U.S. will face Italy in the bronze medal match in search of its fourth Olympic medal in men's team foil.
This is the end of wild, shirt-ripping celebrations in the men's discus?
Defending Olympic and triple world champion Robert Harting missed out on Saturday's final when he finished only 15th in qualifying with a throw of 62.21 meters, 47 centimeters shy of a place in the final.
The outspoken German known for his anti-doping views is best remembered across the world for his antics when he wins. If he doesn't roar and rip his shirt off, he might be celebrating by jumping the hurdles with a national flag aloft.
He missed last year through injury and has found it tough to come back this season.
Piotr Malachowski of Poland was the top qualifier with 65.89.
Harting's younger brother Christoph went through as third.
In a bittersweet victory that came down to a measurement in the final round, American Brady Ellison knocked off fellow countryman Zach Garrett 6-4 to advance to the quarterfinals in the men's individual archery at the Rio Games on Friday.
Ellison went into the final round with a narrow 5-3 lead and the pair tied 29-29 to give the No. 2 seed the victory. The two were forced to wait anxiously as judges measured how close to center they were.
Ellison will face Japan's Takaharu Furukawa in the quarterfinal round. The No. 7 seed defeated Spain's Liebana Rodriguez 7-3 to advance.
Australia's Taylor Worth will face Korean Ku Bonchan in the quarterfinal round. Worth advanced with a 7-3 win over Spaniard Antonio Fernandez and Ku defeated Germany's Florian Floto 6-4.
Italian Mauro Nespoli cruised past Indonesia's Riau Ega Agatha 6-0 to face Frenchman JC Valladont, who swept Thailand's Witthaya Thamwong 6-0.
Korea's Lee Seungyun will take on the Netherland's Sjef van den Berg after defeating India's Atanu Das 6-4. Van den Berg squeaked Chile's Ricardo Soto 6-5.
The Polish Weightlifting Federation says that it has received information from the Commission Against Doping in Sport that Adrian Zielinski, who won a gold medal at the London Olympics in 2012, has tested positive for a performance-enhancement substance, nandrolone.
The federation said on its website on Friday that the sample was taken from Zielinski on July 1 during a competition in Poland.
Polish media are reporting that Zielinski will not be allowed to compete at Rio and that he is preparing to return to Poland.
He is quoted as denying having taken banned substances and said he has no idea how the substance could have been found in his body.
The Polish Weightlifting Federation says he has a legal right to a B sample.
Earlier in the week Zielinski's brother Tomasz, also a weightlifter, was also sent home from Rio after testing positive for nandrolone, a steroid.
The IAAF has suspended the Kenyan Olympic track team's manager over allegations that he sought bribes from undercover reporters to protect athletes from doping tests.
The IAAF says Friday that Michael Rotich, who was sent home from the Olympics in Rio de Janeiro last weekend, is suspended for 180 days while the track governing body investigates.
He is the fourth athletics federation official in Kenya to be put under investigation for attempting to cover up doping.
Also Friday, the athlete caught up in a second Kenyan doping scandal at the Olympics says he has ''explained everything.''
Ferguson Rotich, who ran on the opening day of track and field in Rio, is being investigated after a coach was found with his accreditation and pretended to be the runner at a doping test.
France's Teddy Riner – the most successful judoka of all time – is through to the semifinals of the Rio de Janeiro Olympics.
The heavyweight Riner, who has not lost a match since 2010, defeated Brazilian hopeful Rafael Silva in the quarterfinals on Friday, with a single throw that was ultimately enough to win; Silva did not score.
Top-ranked Riner holds a record-holding eight world championships and also took the Olympic title at the London Olympics. He will face Israel's fifth-ranked Or Sasson in the semifinal on Friday afternoon.
Sasson defeated Egyptian fighter Isalm El Shehaby in the first round; El Shehaby refused to shake Sasson's hand in a breach of judo etiquette and was called back to the mat by the referee, where he gave a perfunctory bow of his head. El Shehaby was loudly booed on exiting the arena.
MEDAL ALERT : Almaz Ayana of Ethiopia set a world record in the 10,000 meters with a stunning solo run to win the first gold medal of the athletics program. Vivian Cheruiyot of Kenya took silver.
Ayana finished in 29 minutes, 17.45 seconds. The old record of 29: 31.78 of China's Wang Junxia stood since 1993.
At 24, Ayana is now poised to become the next dominating long-distance runner and is also going for gold in the 5,000 meters next Friday. She is unbeaten this season.
Tirunesh Dibaba took bronze, missing out on the chance to become the first woman to win three individual gold medals in a row.
Britain's rowing team has clinched a second consecutive gold in Rio by winning the men's four ahead of Australia.
It was the country's fifth consecutive Olympic title in an event that's become as British as afternoon tea.
Alex Gregory, Mohamed Sbihi, George Nash and Constantine Louloudis were in a tight race with Australia's four with only two-tenths of a second separating the crews at the half-way mark.
But the Australians fell back in the latter half of the race as the Brits won by nearly two seconds. Italy got the bronze.
Britain has won a total of nine gold medals in the men's four. The only country that has more Olympic titles in a rowing event is the United States, which has 12 in the men's eight.
Germany's Henri Junghaenel has captured gold in men's 50-meter prone rifle after an impressive shooting display.
Junghaenel, a four-time All-American at the University of Kentucky, hit a near-perfect 10.8 four times in his first Olympics to outlast South Korea's Jonghyun Kim. Junghaenel briefly lost the lead to Kim late in the finals, but closed out gold with a 10.7 and 10.4 on his final two shots to finish 1.3 points ahead of Kim.
Kim tied Russian's Kirill Grigoryan in the bronze medal round and hit a perfect 10.9 to win a win shoot-off to take silver.
The 24-year-old Grigoryan hit 9.7 on his final shot to earn bronze.
Usain Bolt's parents are confident he will defend his titles in both the 100 meters and 200 meters at the Rio Olympics.
Wellesley and Jennifer Bolt visited their son Thursday night in the Athletes Village and asked him if he was healthy and prepared for his final Olympics. Bolt pulled out of his national championships last month with a sore hamstring, but has insisted he's fine to compete in Brazil.
Jennifer Bolt said when she asked her son if he was ready to go Sunday, he said: ''Mom, if I wasn't ready, I wouldn't be here because I'm not into the losing thing. I'm ready.''
Bolt is trying to win the 100, 200 and 4×100 relay – which he has in the last two Olympics – to close his career with nine gold medals.
British rowers Helen Glover and Heather Stanning have successfully defended their Olympic gold in the women's pair.
The Brits, world champions in the event, came out of the blocks the quickest and never lost their lead on the 2-kilometer course.
New Zealand's Genevieve Behrent and Rebecca Scown were in last place after 500 meters but fought back to grab the silver ahead of Denmark's Hedvig Rasmussen and Anne Andersen.
The United States remains without rowing medals in Rio after Felice Mueller and Grace Luczak dropped to fourth place after a strong start.
Pierre Houin and Jeremie Azou won France's first rowing gold medal at the Rio Olympics, beating Ireland and Norway to the finish line in the lightweight men's double sculls.
The French world champions led the race from start to finish but the Irish and Norwegian crews came dangerously close in the final 50 meters.
Just 69 hundreds of a second separated the winners from bronze medalists Kristoffer Brun and Are Strandli of Norway.
