What to Watch at the Olympics This Weekend

You love the Olympics, but you’re no expert , not even an aficionado. What to watch? Below, some highlights. Below that , what happened in the events we flagged for you earlier . Events can be live-streamed on NBC’s website. Check back here daily for more previews of the drama in Rio .

Friday, Aug. 12

9 p. m. ET A packed night swimming session is a highlight of Day 7.

Today might be a little slacken for American fans, but tonight’s swim session should be one of the most entertaining of the entire Olympics. Twenty-six-time medalist Michael Phelps’s last individual event will be the 100 -meter butterfly, an event in which he has claimed three straight gold medals, and 19 -year-old star Katie Ledecky could tie the American record with her fourth gold medal if the world record-holder wins the 800 -meter freestyle as expected.

Those who like pure speed should also tune in Friday, as America’s Nathan Adrian and Australias Cameron McEvoy go head to head in the 50 -meter freestyle final.

Saturday, Aug. 13

8: 30 a.m. ET Usain Bolt flashes by .

Speed is a theme again as the fastest humen in the world compete in the preliminary heats of the 100 -meters. Jamaicas Usain Bolt, who holds the world record in the 100 meters and 200 meters and won gold in both events in 2008 and 2012, is the favorite in the event. But American Justin Gatlin could end Bolts dominance in the Olympics. The 2012 bronzes medalist finished 0.01 seconds behind Bolt in the event at the 2015 IAAF World Championships.

9 p. m. ET Phelps concludes his fifth Olympics with the 4-x-100 meter medley relay .

After the womens 100 -meter final at 7 p. m ., Phelpss fifth Olympics will come to an end in what should be an exciting final swimming event in Rio. The U.S. and Australia will likely do battle for gold in the event, which will feature specialists in the butterfly, backstroke, breaststroke, and freestyle.

Sunday, Aug. 14

11 a.m. ET The humen tennis final could offer a battle between Rafael Nadal and Andy Murray .

Unlike men’s golf, which has taken a back seat in Rio after the top four players in the world pulled out of the field, the top men’s tennis players traveled to Brazil to compete ahead of the year’s final major. Although Serena Williams and Novak Djokovic, the top women’s and men’s players, both lost in the early rounds, the quality tennis isn’t over. Two members of the Big Four are still alive in the event: Rafael Nadal, who has considered the past few seasons derailed by traumata, and Andy Murray, fresh off his second career Wimbledon win.

Juan Martin del Potro knocked out Djokovic and could spoil the Nadal-Murray showdown if he advances to the final, but a matchup between the 6-foot-6 Argentinian grand slam champion and Murray would also be scintillating.

Those who still want to see how men’s golf fares in the Olympics, in its return for the first time since 1904, can enjoy the final round at the same time as the men’s tennis final.

1 p.m. ET The gymnastics individual event finals begin .

Individual all-around champion Simone Biles will aim for her third gold medal of these Games in the womens vault final. The afternoon will also feature event specialist Madison Kocian in the womens uneven bars final and mens individual events in the floor exercise and pommel horse, which can be streamed live but is likely to be tape-delayed for 7 p. m. on NBC.

7:20 p.m. ET Bolt and Gatlin do battle in the 100 -meter final .

Sunday will mark approximately the halfway point of the Olympics and will culminate in one of the Games most exciting events, the 100 -meter humen final, which could end up as another showdown between Bolt and Gatlin. Can the world’s fastest human captivate the world again?

And here’s what happened in those events we flagged earlier :

Thursday, Aug. 11

Biles was trailing after two of four events in the women’s gymnastics all-around final. Regrettably for the rest of the field, the latter are two of the 4-foot-8 star’s best. Already considered the best female gymnast ever, Biles captured her first individual Olympic gold medal with a 2.1 -point margin of victory ahead of American teammate Aly Raisman, who won silver. Biles’s margin of victory was wider than the margins from 1980 to 2012 combined. Raisman redeemed herself after scarcely missing out on an all-around medal four years ago. Biles, Raisman, and the rest of Team USA will compete in individual event finals starting Sunday and continuing into next week.

Not to be outdone by Biles’s dazzling performance, Phelps reminded the world how much he still has left in the tank in his fifth Olympics. The greatest Olympian of all time left the rest of the fieldwhich featured rival Ryan Lochte and Japanese superstar Kosuke Haginobehind in the final 100 meters of the 200 -meter individual medley, winning easily, by two seconds. Only 30 minutes after capturing his fourth gold of these Games, Phelps qualified for the final in the 100 -meter butterfly.

Wednesday, Aug. 10

After dominating overmatched opponents China and Venezuela in its first two Olympic games, the U.S. men’s basketball team passed its first real exam by beating Australia 98 -8 8 Wednesday night. Led by NBA players Matthew Dellavedova( 11 phases and 11 assists ), Patty Mills( 30 points and six 3-pointers ), and Andrew Bogut, the Australians put a scare into the Americans early in video games, taking a halftime leading and maintaining it close until the final minutes.

But Carmelo Anthony and Kyrie Irving made sure the U.S. would bide unbeaten in Rio. Anthony scored 31 points and Irving added 19 phases and five assistances, with the duo hitting several 3-pointers in the game’s final minutes to permit Mike Krzyzewski’s team to pull away.
