Jackson edges Fraser-Pryce to win world 200m gold
Newly-crowned 100m gold medallist Fraser-Pryce took silver in 21.81 seconds, with defending champion Dina Asher-Smith of Britain claiming bronze (22.02).
All eyes had been on Fraser-Pryce, sporting a long mane of dyed purple hair, in her bid for a second sprint double after having achieved the feat at the 2013 Moscow Worlds.
Fast out of the blocks in lane six, Fraser-Pryce rocketed past Niger's Aminatou Seyni in no time, running a great bend to hit the back stretch neck-and-neck with Jackson, in four.
As the two Jamaicans went head-to-head, Jackson put on the afterburners and pulled away in impressive style, not giving up until she thundered through the line.
Fraser-Pryce swept through on her coattails, with Asher-Smith holding off Seyni for bronze.
Olympic champion Elaine Thompson-Herah, the third part of Jamaica's clean sweep of the 100m along with Fraser-Pryce and Jackson, eventually came in seventh in 22.39 seconds.
