If this year's edition of the World Athletics Championships has proven anything, it's that there's a new star on the American track and field stage.
Melissa Jefferson-Wooden of Georgetown, S.C., won the 200-meter world championship Friday in Tokyo with a time of 21.68—the best in the world this year. In doing so, she became the first female sprinter since Jamaica's Shelly-Ann Fraser-Pryce in Moscow in 2013 to sweep both the 100- and 200-meter events.
