RIO DE JANEIRO — Day 12 of the Rio Games features medal action in track and field, beach volleyball, wrestling and more. Here are some things to watch:
TRACK AND FIELD
Expect a good showdown between Dafne Schippers of the Netherlands and Tori Bowie of the U.S. in the 200 meters at 8:30 p.m. following semifinals Tuesday night. Bowie is coming off a silver in the 100. There's no worry about Allyson Felix, the reigning Olympic champ, because she didn't qualify at Olympic trials.

The American women are thinking sweep in the 100 hurdles at 8:55 p.m. This despite world record holder Keni Harrison not even making the team at trials. It's that deep.
American Brittney Reese gets started in trying to defend her long jump title at 7:15 p.m.
Ashton Eaton of the U.S. kicks off the defense of his decathlon title. He's trying to become the first to win back to back decathlon titles since Daley Thompson of Britain in 1980 and 1984.
And then, of course, there's Usain Bolt as he takes another step toward another sweep in the sprints. The Jamaican was 3 for 3 in Beijing and again in London. And so far he's 1 for 1 in Rio. Semifinals start at 8 p.m.
After meeting in the semifinals of the last three Olympics, the U.S. men's basketball team and Argentina square off in the quarterfinals at 4:45 p.m. The Americans, challenged in their last three games, would fail to medal in the Olympics for the first time with a loss.
Other games will see Australia vs. Lithuania at 9 a.m., Spain vs. France at 12:30 p.m. and Serbia vs. Croatia at 8:15 p.m.
Brazilian world champions Agatha and Barbara knocked off Americans Kerri Walsh Jennings and April Ross to reach the gold-medal game against Germany's Laura Ludwig and Kira Walkenhorst at 9:59 p.m.
Walsh Jennings was going for her fourth gold, and Ross was looking to improve on the silver she earned when she lost to her fellow Americans in the London final.
The U.S. will face top-seeded Brazilian women Talita and Larissa at 8 p.m. in the bronze medal match.
Host nation Brazil will have its eyes on Neymar and company as they take on Honduras at 11 a.m. in the semifinals. It's been a rocky road for the team — starting with two draws (South Africa, Iraq) but following with shutout wins over Denmark and Colombia. Honduras had two wins, a loss and a draw.
At 2 p.m., Nigeria and Germany play in the other semifinal. The gold medal match is Saturday.
China is looking to cement its domination of table tennis by repeating in Rio what it did in London: sweeping gold in the singles and team competitions. The gold medal team competition against Japan starts at 5:30 p.m.
China's Ma Long has already taken gold over fellow countryman Zhang Jike, and Ding Ning beat fellow Chinese player Li Xiaoxia. The women's team won Tuesday and if the men win, as widely expected, China will have taken all the golds in play in Rio.
Germany and South Korea play for the bronze.
The women have all the best players. Now they try to live up to men's sensational performance in Olympic golf.
Lydia Ko of New Zealand, Brooke Henderson of Canada and the top nine women in the world tee it up starting at 5:30 a.m. at Olympic Golf Course, the first time for women playing golf in the Olympics since 1900.
Inbee Park is among four South Koreans in the 60-player field. The seven-time major champion has not played on the LPGA Tour in two months because of a thumb injury. The Americans have three players, including newlywed Stacy Lewis.
Even though six of the top 10 men did not come to Rio, it ended with high drama when Justin Rose made birdie on the last hole to beat Henrik Stenson, with Matt Kuchar closing with 63 to take the bronze.
The U.S. will face Poland in the quarterfinals at 12 p.m. after the Americans won their final three pool-play matches following an 0-2 start. Canada, back in the Olympics for the first time since 1992, plays defending Olympic champion Russia in the opening quarterfinal at 10 a.m.
Italy takes on Olympic first-timer Iran at 4 p.m., while host Brazil advanced on the final day of preliminary play Monday and draws Argentina at 8:15 p.m.
Japanese wrestler Kaori Icho will attempt to become the first woman to win an individual gold at four consecutive Olympics. Five men have done it, including Carl Lewis and Michael Phelps (2016)
Top American boxer Claressa Shields fights for the first time in the tournament. Shields unexpectedly dominated the first Olympic women's boxing tournament in London and won the gold medal. She's a favorite to win another. Shields hasn't lost a fight since London, winning two world championships and a Pan-American Games title. The fight is scheduled for 12:30 p.m.
Uzbekistan fighter Shakhram Giyasov faces Daniyar Yeleussinov of Kazakhstan at 2:30 p.m. for the men's welterweight gold.
It's time for BMX racers to hit the green track at the Summer Olympics, with seeding runs starting at 11:30 a.m. to set up the men's quarterfinals that begin Thursday. Maris Strombergs of Latvia, the only man to win the event since BMX was added to the Olympics in 2008, is going for a third straight gold. On the women's side, Mariana Pajon of Colombia is the defending champ.
