The Latest on the Olympics being held in Rio de Janeiro (all times local):
4:15 p.m.
The three-time defending champion U.S. women's national team will miss the Olympic final for the first time after the Americans were ousted from after falling to Sweden on penalties following a 1-1 draw in the quarterfinals on Friday.
Even after three rounds, Sweden captain Caroline Seger beat Hope Solo, and Christen Press' attempt against Hedvig Lindhal went over the net. With the next kick, Lisa Dahlkvist beat an outstretched Solo to for the win.
As Sweden celebrated the victory, captain Carli Lloyd crouched in defeat on the field at Mane Garrincha Stadium. It was the first time that an Olympic women's match had gone to penalties.
It also was the earliest the United States had ever been eliminated from the Olympics since women's soccer became a sport in 1996.

A Chinese swimmer, Polish weightlifter and Bulgarian steeplechaser have been sanctioned for doping offenses at the Olympics.
The Court of Arbitration for Sport says weightlifter Tomasz Zielinksi and steeplechaser Silvia Danekova have been kicked out of the games after testing positive for banned substances.
Swimmer Chen Xinyi, meanwhile, accepted a "provisional suspension on a voluntary basis" after testing positive for a diuretic. CAS says the case will continue, with a final decision to be issued before the end of the games.
The 18-year-old Chen's Olympics are now over anyway. She finished fourth in the 100-meter butterfly on Sunday and pulled out before Friday's 50-meter freestyle, her final event.
These were the first decisions issued by CAS, which is handling doping cases at the Olympics for the first time.

Authorities say a German Olympic canoeing coach underwent surgery and remains in a serious condition in a Rio de Janeiro hospital after being injured in a car accident early Friday in Rio de Janeiro.
Rio Olympics spokesman Mario Andrada says the canoe slalom coach, who has not been publicly identified, was one of two members of the German delegation heading back to the athletes' village in a taxi that was involved in the accident.
Paula Fiorito, a press official at Rio's health department, said the coach was in intensive care following unspecified surgery.

MEDAL ALERT: Diana Bacosi has captured gold in women's skeet. American Kim Rhode has made history.
Bacosi hit 15 of 16 targets to defeat fellow Italian and 2008 gold medalist Chiara Cainero in the final match for her first gold medal.
Rhode defeated China's Mei Wang in a shoot-off to claim bronze. She and Italian luger Armin Zoeggeler are now the only athletes to earn a medal in six straight Olympics, with Rhode being the first woman to accomplish the feat.
She has six medals, including three golds, to become the most decorated female shooter in Olympic history.
Rhode also ties the record for most years between medals after winning double trap gold as a 17-year-old at the 1996 Atlanta Games.
American Morgan Craft finished fifth.

MEDAL ALERT: Wang Zhen of China has won the men's 20-kilometer racewalking gold medal at the Rio Games, with Chinese teammate Cai Zelin taking the silver.
Wang's winning time was 1 hour, 19 minutes, 14 seconds. He beat Cai by 12 seconds, and Australia's Dane Bird-Smith was another 11 seconds back to take the bronze medal.
The race came just one day after the Court of Arbitration for Sport dismissed the appeal of Italian racewalker Alex Schwazer — the 2008 Olympic champion in the 50-kilometer racewalk — and imposed an eight-year ban for steroid usage. Schwazer also missed the 2012 London Games following a ban for another doping offense.
Wang was the bronze medalist in the same event at the London Games four years ago. It's the second straight gold for China in the event, after Chen Ding won in London.

The United States blew away the field in the women's swimming 4×100-meter medley relay heats at the Rio Games.
Olivia Smoliga, Katie Meili, Kelci Worrell and Abbey Weitzeil qualified fastest in 3 minutes, 54.67 seconds Friday for the relay featuring all four strokes. They were 2.13 seconds ahead of Canada.

Another day, another Olympic record for Marcus Fraser of Australia.
Of course, with golf back in the Olympics for the first time in more than a century, new marks will be set after each of the four rounds.
Marcus followed his opening-round 63 with a 2-under 69 on Friday for a one-shot lead over Thomas Pieters of Belgium at the halfway point. He was at 10-under 132.
Henrik Stenson was two shots behind, and his second round did not lack of excitement. The British Open champion was caught in the worst of the rain early in his round, but he escaped the bad conditions by making a 108-foot par putt. Stenson calls it the longest putt of his career.
He wound up with 68.
The Americans showed signs of life, except for Rickie Fowler. He shot a 71 and was 14 shots out of the lead. That means Fowler likely will go home with plenty of selfies, just no medal.

UPSET ALERT: The United States women's soccer team has been eliminated by Sweden in the quarterfinal at the Rio Games. The Friday match was a stunning loss for the U.S. team, which has played in the final every year since women's soccer became an Olympic sport 1996, winning gold four times.

The U.S. women's Olympic quarterfinal against Sweden has gone to penalty kicks after a 1-1 draw.
It is the first Olympic women's match to go to penalties.
After a scoreless first half, Stina Blackstenius scored in the 61st minute to give Sweden a 1-0 lead that for a time threatened to send the Americans home early from Brazil. The United States has played in the final every year since women's soccer became an Olympic sport 1996, winning gold four times.
Alex Morgan scored the equalizer in the 78th minute and the match went to overtime. Carli Lloyd was called offside on a header in the 115th minute and a minute later Lotta Schelin was offside on her attempt against Solo — although replay appeared to show otherwise.

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.

2:20 p.m.
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.
Whoa.
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.

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.

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.

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.
