Team USA closes the World Athletic Championships in Berlin at the top of the medal count and a sweep of the men's and women's 4x400 meter relays. LaShawn Merritt (400m) and Kerron Clement (400m hurdles)—both seen above—Allyson Felix and Sanya Richards each won a second gold medal Sunday. Olympic gold medalist Angelo Taylor also won gold.
The United States has 10 gold medals and 22 overall. Jamaica was second with seven gold and 13 overall. Russia also boasts 13 overall.
Team USA's performance at the 4x400 relays was a marked improvement over the incredible disappointments at the 2008 Olympics in Beijing, when the two sprint relay teams clumsily dropped the baton. Jeremy Wariner, who won silver in the 400m and seen below passing the baton to Clement: "We expect greatness. That's what we did today. We showed greatness."
