Jamaican Shericka Jackson became world champion in the 200m by setting the second best time of all time (21 sec 45, 0.6 m/s wind) Thursday in Eugene (Oregon).
Just 11 hundredths from the old world record of American Florence Griffith-Joyner (21.34 in 1988), Jackson (28) beat her compatriot Shelly-Ann Fraser-Pryce (21.81), winner of the 100m on Sunday, and the British defending champion Dina Asher-Smith (22.02).
