Rio Olympics: Stars to watch

Track and field, men's 200-meter final
When:
9:30 p.m.
After being the first person to win the 100 meters three times, Usain Bolt will try to accomplish the same feat in the 200. Unlike in the 100, American Justin Gatlin won't give Bolt a run for his money. Gatlin, who won silver behind Bolt at last year's world championships, failed to make the final after leading during most of his semifinal. Watch out for Bolt's pal, Canadian Andre De Grasse.
