Here are some of the highlights from Day 7 in Rio:

Shattering a record: Almaz Ayana of Ethiopia delivered a stunning start to track and field at the Olympics with a world record in the 10,000 meters Friday, wiping away the competition just after the halfway point and striding to victory with effortless grace. After crossing the finish line, she raised her hands in triumph and came to a stop, fully realizing what she had done: Her time of 29 minutes, 17.45, had shaved 14.33 seconds off the 1993 mark of China’s Wang Junxia. At age 24, she beat the best from a previous generation. Kenya’s Vivian Cheruiyot, 32, a four-time long distance world champion came in second, a massive 15.18 seconds behind. Ayana’s 31-year-old teammate Tirunesh Dibaba took bronze.

Too close for comfort: Kyrie Irving scored 15 points and the U.S. men’s basketball team survived its second straight strong challenge in the Rio Games, edging Serbia 94-91. The Americans won their 48th consecutive international tournament game, but it was anything but easy. Serbia’s Bogdan Bogdanovic missed a 3-pointer from the left wing with 2 seconds left that would have tied it, and Kevin Durant grabbed the rebound to keep the Americans unbeaten. They barely escaped against Australia on Wednesday. DeAndre Jordan scored 13 and Carmelo Anthony 12 for the U.S., which will close pool play on Sunday against France.

Make that 45: Maya Moore scored 12 points, and the U.S. routed Canada 81-51 to clinch Group B in women’s basketball. The U.S. won its 45th straight Olympic game after a sloppy start where the Americans (4-0) had their two lowest scoring quarters in Rio. They led only 18-16 after the first quarter and only could match that total in the second. Yet the U.S. led 36-22 at halftime after forcing Canada into 15 turnovers and limiting the Canadians to one made field goal in the second quarter. Diana Taurasi also had 12 points, and Tina Charles added 10.

Doubling down: Rafael Nadal added a second Olympic tennis gold medal to all of those Grand Slam trophies, teaming with Marc Lopez to win the men’s doubles championship for Spain at the Rio de Janeiro Games. Nadal and Lopez came back from a break down in the third set and claimed the last three games to beat Florin Mergea and Horia Tecau of Romania 6-2, 3-6, 6-4 in the final Friday. Nadal, a 14-time champion at major tournaments, also won an Olympic title in singles at the 2008 Beijing Games. This is the first medal for Lopez. The silver for Mergea and Tecau is the first tennis medal for Romania in Olympic history.

Bronze boxer: Nico Hernandez’s chance for a gold medal ended Friday when he lost to Uzbekistan’s Hasanboy Dusmatov. With a gnarly gash over his left eye, Hernandez had blurred vision and needed stitches. His consolation: his bronze medal in the light flyweight division ends a medal drought for the American boxers that stretched to 2008.

Puig’s push: Tennis player Monica Puig is one victory from Puerto Rico’s first gold medal in Olympic history. Puig continued her surprising run by reaching the women’s singles final, eliminating two-time Wimbledon champion Petra Kvitova of the Czech Republic 6-4, 1-6, 6-3. Puig is ranked 34th and unseeded but is assured of no worse than a silver medal.

Adding to the count: Bradley Wiggins and Britain are Olympic champions once again. This time in record-setting fashion. The team pursuit squad of Wiggins, Ed Clancy, Steven Burke and Owain Doull beat Australia in record-setting time at the Rio Games on Friday night, winning the gold medal for the third straight time and making Wiggins the most decorated Olympian in British history. It was the fifth gold for the former Tour de France champion and eighth medal overall, breaking a tie with retired track cyclist Chris Hoy for most by a British athlete. Wiggins has now won medals in every Olympics dating to the 2000 Sydney Games.
