Usain Bolt practically jogged through the first round of qualifying for the 200 on Tuesday; he'll probably breeze through the semifinals Wednesday. It The women's 200 final should be a showdown between Dafne Schippers of the Netherlands and Tori Bowie of the U.S. The decathlon also kicks off, with Ashton Eaton trying to defend his title.
Soccer
Brazil's men haven't been playing that well, but they face Honduras in one of the semifinals. In the other semifinal, Nigeria plays Germany. So, if Brazil and Germany win, the final will be a rematch of the World Cup semifinal where Germany embarrassed the host nation with a 7-1 win.
Boxing
The best boxer for the U.S. goes Wednesday, and her name is Claressa Shields. She dominated in London and has done well since then, having not lost a match in those four years. She automatically qualified for the quarterfinals, so a win over Yaroslava Yakushina of Russia guarantees a medal.
