TOKYO (Reuters) - American Melissa Jefferson-Wooden became the fourth woman to complete the sprint double at the world championships with victory in the 200 metres in 21.68 seconds on Friday.
The 24-year-old American ran the fastest time of the year to cap a brilliant season with another gold medal to add to the one she won in the 100m on Sunday.
Britain's Amy Hunt was a distant second to take silver in 22.14, while bronze went to double defending champion Shericka Jackson of Jamaica in 22.18.
Jefferson-Wooden matched Jamaica's Shelly-Ann Fraser-Pryce (2015) and Germans Silke Gladisch (1987) and Katrin Krabbe (1991) by winning both sprints at the same world championships.
