USA's Jefferson-Wooden golden with 100m title

TOKYO -- 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 blew away the field, finishing in 10.61 seconds to break Sha'Carri Richardson's two-year-old world championship record. Richardson barely squeezed into the final and finished fifth despite running a season-best 10.94.

Seville, who works with Usain Bolt's old coach, Glen Mills, reeled in countryman Kishane Thompson for a win in 9.77. Defending world and Olympic champion Noah Lyles finished third.
