In Doha, Fraser-Pryce cruised to 10.80 s in the 100 m heats, the fastest first-round time in World Championships history. She followed with 10.81 s in the semifinal, the fastest qualifying time ahead of the final. In the 100 m final, she outpaced the field from the start, powering away to her fourth title in a world-leading 10.71 s—her fastest time since 2013. Her teammate and rival Thompson finished fourth in 10.93 s. It was the first time Fraser-Pryce had defeated Thompson in their six career matchups. With this achievement, Fraser-Pryce became the oldest woman ever and first mother since Gwen Torrence at the 1995 World Championships to claim a 100 m global title. She took particular satisfaction in her win, calling it "a victory for motherhood," and brought her two-year-old son on her victory lap around the stadium. Days later, she added another gold medal to her collection by running the second leg of the Jamaican 4 × 100 m relay team, her ninth world title overall. She had also planned to contest the 200 m, but later withdrew.
