Olympic champion Elaine Thompson-Herah scored an emphatic 100m victory over the returning Sha’Carri Richardson at the Prefontaine Classic in Oregon on Saturday.  Jamaican star Thompson-Herah powered over the line at Hayward Field in 10.54sec—the second fastest time in history—as Richardson finished a distant last in 11.14sec.

Thompson-Herah’s winning time saw her slice 0.07sec off her Olympic record of 10.61sec set on July 31. Only the late Florence Griffith Joyner has ever run faster, with Thompson-Herah now tantalisingly close to the American’s 33-year-old world record of 10.49sec.
