Team(s)/Athlete(s) of Interest: Veronica Campbell-Brown

Time: 4:00 p.m.

Why You Should Watch: It's starting not to look like a sure win for defending gold medalist Veronica Campbell-Brown in the 200m. VCB, who finished just third in her semifinal heat, is looking up at the competition instead of down, going into the finals. Usual suspects like Allyson Felix, Shelly Ann Fraser-Pryce, and Sanya Richard-Ross are still in the field, but now VCB has to worry about Murielle Ahoure, and Mariya Ryemyen, which might be too much to overcome for Campbell-Brown to retain her gold.
