Shericka Jackson of Jamaica let out a joyous scream as she crossed the finish line of the 200-meter final to claim gold Thursday at the World Athletics Championships.

Clocking a time of 21.45 seconds, Jackson finished in front of teammate Shelly-Ann Fraser-Pryce, who won silver, and Great Britain’s Dina Asher-Smith, who captured bronze.

Jackson’s time stands as the second-fastest ever. She becomes only the second woman, joining Florence Griffith-Joyner, to break 21.50 seconds in the event.

Kentucky star Abby Steiner finished fifth, while fellow American Tamara Clark came in sixth.

“First gold medal, national record, personal best and a championship,” Jackson said after the race. “I’m so grateful.”

Jackson’s inaugural gold medal at worlds comes after the 28-year-old clinched first place in June’s Jamaican national championships.
