Defending champion Elaine Thompson-Herah has secured a gold medal at the Olympic 100 metres women's race to become the second-fastest woman in history.
She led her fellow Jamaican compatriots to secure the first, second and third positions; making the race a solid Jamaican victory.
The 29-year-old posted a record of 10.61 seconds while Shelly-Ann Fraser-Pryce; who had been seeking a third gold in the event, took silver at 10.74s. Shericka Jackson came third at 10.76s and will take home a Bronze medal.
"I am really excited to come back and retain my title. My chest hurts, I am so happy," said Elaine, whose time has only been bettered by world record holder Florence Griffith-Joyner at 10.49 in the 1988 Olympics.
Fraser-Pryce took time away from the sport to have a baby but arrived in Tokyo on the back of a sizzling 10.63 run; her fastest time this year.
She started the race strongly, nosing ahead of the field. However Thompson-Herah eventually caught up with her and after the pair raced neck and neck, Thompson-Herah emerged as the winner beating her by some valuable seconds.
This particular race will also be the fastest women's race in history as six of the athletes finished in less than 11 seconds.
