Thompson-Herah wins women's 100m title and beats Fraser-Pryce
Jamaica's Elaine Thompson-Herah set a new Olympic record in the women's 100m as she finished ahead of compatriot Shelly-Ann Fraser-Pryce.
Elaine Thompson-Herah became the second-fastest woman in history as she retained her Olympic women's 100 metre crown in Tokyo with a Games record of 10.61 seconds.
The Jamaican posted a slightly slower time than reigning world champion Shelly-Ann Fraser-Pryce in the heats but pipped her compatriot in Saturday's incredible final at the Olympic Stadium.
Just short of the all-time women's 100m record
Thompson-Herah's time was just 0.12s short of the all-time women's 100m record set by American Florence Griffith-Joyner.
Fraser-Pryce, who won gold in 2008 and 2012 before claiming bronze in 2016, finished in a time of 10.74 and Shericka Jackson completed a Jamaican one-two-three with a personal best of 10.76.
Six of the eight competitors finished under 11 seconds as one of the most hotly anticipated events of the Tokyo Games lived up to its billing.
Fraser-Pryce made a rapid start to what was the quickest women's final in history and led at around the 60m mark, but she was caught by Thompson-Herah and the 29-year-old crossed the line in record time.
Thompson-Herah was forced to withdraw from a Gateshead Diamond League event in May with an Achilles problem that has affected her for several years, yet she battled back from that injury to make it back-to-back gold medals.
Thompson-Herah using negativity as motivation
"I've been struggling with my injury back and forth," she told BBC Sport. "I see all the bad comments, and for me to stay focused, hold my composure... I take all of my losses, all of my defeats and I use them as my motivation."
Fraser-Pryce, who missed more than a year of action around the birth of her son in 2017, said: "It wasn't the best 30m because I had a stumble at about the third step and I never recovered from it.
"Nevertheless I am grateful to be able to come out here and represent what God has given me.
"I am excited because, as a mother and [at] my fourth Olympics, to be able to stand again on the podium is just a tremendous honour. I am hoping wherever in the world, mothers, athletes, females, we understand that there is so much more we can achieve.
"It is crazy, but you know my emotions are still very raw right now. I am sure I will go home and there will be some tears. I have been through this many, many times, so I am just really excited about what I have been able to do tonight."
No medal for Marie-Josee Ta Lou
Marie-Josee Ta Lou of the Ivory Coast, one of five athletes to clock a time below 10.8s this year heading into the Games, finished just outside the medal positions with 10.91s.
Swiss pair Ajla del Ponte and Mujinga Kambundji finished fifth and sixth, while the United States' Teahna Daniels was seventh and Daryll Neita eighth.
Neita's British team-mate Dina Asher-Smith, who took silver at the 2019 IAAF World Athletics Championships in Doha, did not qualify from her semi-final and then withdrew from the 200m – in which she is world champion – as she recovers from a hamstring tear.
