Day 12 of the Rio Games features medal action in track and field, beach volleyball, wrestling and more. Here are some things to watch (all times local):
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 10:30 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 10:55 p.m. This despite world record holder Keni Harrison not even making the team at trials. It's that deep.

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 10 p.m.

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 7:30 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.

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 7:30 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.
