Melissa Jefferson-Wooden of the U.S. and Oblique Seville of Jamaica won the 100-meter finals at the world championships Sunday in a changing of the guard in track.
Jefferson-Wooden, 24, blew away the field in the women’s final, finishing in 10.61 seconds to break Sha’Carri Richardson’s two-year-old world championship record by .04. Richardson barely squeezed into the final and finished fifth despite running a season-best 10.94.
