The Latest: Nadal to semis, seeking 2nd Olympic singles gold

RIO DE JANEIRO (AP) The Latest on the Olympics being held in Rio de Janeiro (all times local):

5:10 p.m.

Rafael Nadal made it to the semifinals in his bid for a second Olympic singles gold, overcoming his Brazilian opponent and a raucous, flag-waving home crowd in the Rio Games' main tennis stadium.

Spain's Nadal, the No. 3 seed, came back to beat 54th-ranked Thomaz Bellucci 2-6, 6-4, 6-2 in 2 hours on Friday.

Nadal was the singles champion at the 2008 Beijing Olympics, then missed the London Games four years ago because of a knee injury.

These Olympics represent the left-hander's first competition since sitting out 2+ months with an injured left wrist he says is not fully healed.

Nadal and Marc Lopez are scheduled to play in the men's doubles final later Friday.

5 p.m.

MEDAL ALERT: North Korea has its first gold medal of the Rio Olympics after Rim Jong Sim won the women's 75-kilogram weightlifting class.

Rim was utterly dominant, lifting 117 kilograms in the snatch and 153 in the clean and jerk for a total of 274, way ahead of the 258 managed by Belarusian silver medalist Darya Naumava, or 257 for Spain's Lidia Valentin Perez.

North Korea won four gold medals in London four years ago but has started slowly in Rio, with only two silver and two bronze medals before Rim's win.

Rim was gold medalist in the 69kg class four years ago and had few serious rivals at 75kg partly because the gold, silver and bronze medalists from that event in 2012 are all suspended after failing drug tests.

4:55 p.m.

Brazil has put another team into the quarterfinals of the Olympic beach volleyball tournament.

Defending world champions Larissa and Talita beat Germany in straight sets Friday on the opening day of the knockout round. Earlier, the other Brazilian women's team advanced when Agatha and Barbara beat China.

Brazil was one of four countries to qualify the maximum of four teams – two men's, two women's – for the Olympics. But the host nation was the only one to have all four make it out of pool play.

The two Brazilian men's teams play Saturday in the Round of 16.

4:55 p.m.

A German Olympic canoeing coach is fighting for his life in a Rio de Janeiro hospital after suffering serious head injuries in a car accident early Friday, officials said.

Stefan Henze, a canoe slalom silver medalist at the 2004 Games, underwent emergency surgery in a Rio hospital to treat the craniocerebral injury.

''His head injuries are live threatening,'' the German Olympic Sports Confederation said in a statement.

Sports scientist Christian Kaeding, who was in the taxi with Henze, was slightly injured and has already been released from hospital.

The Germans were heading back to the athletes' village in the taxi, Rio Olympics spokesman Mario Andrada said earlier Friday.

4:40 p.m.

MEDAL ALERT: Rosie MacLennan of Canada defended her Olympic title win women's trampoline, edging Great Britain's Bryony Page for gold on Friday afternoon.

MacLennan posted a score of 56.465 in the finals, just a touch better than Page's 56.040. Li Dan of China earned bronze.

MacLennan was third during qualifying but put together an aggressive series of 10 skills that sends gymnasts two stories repeatedly into the air over the course of their one-minute routine. MacLennan appeared to wander outside of the target box on the tramp midway through her set but recovered and received a massive roar as she settled her feet on the tramp during her dismount.

4:30 p.m.

MEDAL ALERT: Germany won gold in the dressage on Friday, edging out defending champion Britain despite another brilliant performance from Charlotte Dujardin.

The German team of Isabell Werth, Kristina Broring-Sprehe, Dorothee Schneider and Sonke Rothenberger posted a score of 81.936 percent, with the British team of Dujardin, Carl Hester, Spencer Wilton and Fiona Bigwood finishing on 78.602.

The United States was third on 76.667, with former hairdresser Laura Graves recording a personal best of 80.644 in her first Olympic Games.

The results are calculated using the average of the three best riders' scores from each

nation from Friday's Grand Prix Special as well as the previous day's Grand Prix.

Three of the top four finishers were German, with Dujardin posting the second highest score after an uncharacteristic error from her horse Valegro.

The individual Olympic champion still managed a score of 83.025, with Werth achieving 83.711 on Weihegold Old.

4:25 p.m.

Britain has topped the qualifying heats for the men's 4×100-meter medley relay in the Olympic pool.

Chris Walker-Hebborn, Adam Peaty, James Guy and Duncan Scott were clocked in 3 minutes, 30.47 seconds Friday.

The U.S. team of David Plummer, Kevin Cordes, Tom Shields and Caeleb Dressel were second fastest in 3:31.83.

Also moving into the nighttime final was host country Brazil, which grabbed the seventh spot, ensuring fans at the Olympic Aquatics Center will be cheering loudly.

Michael Phelps will join the Americans for the final, giving him a chance to add to his gold-medal haul in Rio.

4:25 p.m.

Cuba continues to be the surprise of men's beach volleyball after a straight-sets victory over Austria sent Nivaldo Diaz and Sergio Gonzalez into the quarterfinals.

The Cuban team had played in only one major international competition before and took an unusual path to the Olympics through a regional qualifier.

The Cubans went unbeaten in pool play by beating Brazil's No. 2 team, the fourth-overall seed, as well as Canada, Latvia and a German team that had a pair of three-time Olympians.

4:25 p.m.

The Argentine women's volleyball team has an Olympic victory at last.

The team made history with its first Olympic volleyball victory during pool play Friday in the Rio Games, and it took a hard-fought five-setter against Cameroon to finally taste success on the sport's biggest stage.

Captain Paula Yamila Nizetich called the win ''very special'' but noted there's ''another very important match coming up in order to keep playing in this tournament.''

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.

4:10 p.m.

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.

4:10 p.m.

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.

4 p.m.

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.

4 p.m.

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.

4 p.m.

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.

The Canadians were timed in 3:56.80, followed by Denmark in 3:56.98.

In the nighttime final, 100 free champion Simone Manuel figures to swim the anchor leg for the U.S.

4 p.m.

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.

3:45 p.m.

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.

3:35 p.m.

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.

3:35 p.m.

American Kim Rhode has captured bronze in women's skeet, becoming the first woman to earn a medal in six straight Olympics.

Rhode and China's Wei Mang both hit 15 of 16 shots in the bronze medal match, forcing a shoot-off.

Rhode hit seven targets to Wei's six, joining Italian luger Armin Zoeggeler as the only athletes to earn a medal in six straight Olympics

Rhode has three gold medals and six overall in a career that started with her winning double trap gold as a 17-year-old at the 1996 Atlanta Games.

Italians Chiara Cainero and Italian Diana Bacosi met in the gold medal match.

3:20 p.m.

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.

3:15 p.m.

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.
