Jamaica completed a one-two-three clean sweep in the women's 100m sprint race in Tokyo, with gold medallist Elaine Thompson-Herah setting an Olympic record.
Thompson-Herah defended the title she won in Rio and became the second-fastest woman in history in the process, recording a time of 10.61 seconds.
Reigning world champion and compatriot Shelly-Ann Fraser-Pryce claimed silver, just .02 seconds ahead of Shericka Jackson as Jamaica completed a clean sweep which was celebrated on Twitter by Usain Bolt.
Legendary sprinter Bolt – an eight-time gold medallist – retired in 2017, and the men's preliminary rounds struggled for big names in his absence.
Jamaica will have another chance of a medal in athletics, with 2019 world champion long jumper Tajay Gayle overcoming injury to make Monday's final with a leap of 8.14m.
Sweden sealed a one-two in the men's discus – Daniel Stahl taking gold and Simon Pettersson silver – while Poland won their second Olympic gold medal in a relay event in athletics, their mixed team succeeding in the same city in which their women had tasted victory in 1964.
NO LUCK FOR NOVAK
Djokovic's Golden Slam hopes were ended on Friday, and on Saturday, his medal hopes crumbled.
The world number one lost to Spain's Pablo Carreno Busta, who won 6-4 6-7 (6-8) 6-3 in the bronze medal match in the men's singles.
For Djokovic, it was a defeat which represented the end of his campaign.
He would have had another shot at bronze in the mixed doubles alongside Nina Stojanovic, but withdrew from that match, handing the medal to Ash Barty and John Peers of Australia in the process.
"The exhaustion, both physical and mental, got to me and it's unfortunate that in the most important matches I just didn't deliver, but I gave it all," said Djokovic, whose attention will now turn to winning the US Open to complete a calendar Grand Slam.
BLACK FERNS RIGHT RIO WRONGS
New Zealand's women clinched gold in the rugby sevens on Saturday, overcoming France 26-12.
The Black Ferns cruised to the final in 2016, but slumped to a defeat to rivals Australia. Co-captain Portia Woodman was pictured in tears on the field in Brazil, yet her team made no such mistake this time around.
"Crying underneath the posts was one that I looked back on, but now it's gone," Woodman said. "Not when I look at this," she added, gesturing to the gold medal around her neck.
"Yeah, we've got titles and we've won things, but I want our group to be good people and show the world that you can be a good, genuine person and still have success," Woodman's fellow co-captain Sarah Hirini said.
"Our programme allowed that. Things like this happen because you're able to be who you are."
In the bronze medal match, Fiji defeated Great Britain 21-12.
"We are totally gutted. We really thought we could come here and get a medal, but we just weren't good enough," conceded Team GB's Hannah Smith. "Fiji really brought it to us today, so fair play to them."
DEBUT BRONZE FOR WILSON, CHINA TAKE WINDSURFING GOLD
There was joy for Britain out on the water, however, as Emma Wilson – an Olympic debutant – won bronze in the women's windsurfing.
Wilson was already guaranteed a medal due to winning four races in the lead up to the final. The 22-year-old missed out on silver as Lu Yunxiu of China kept within a boat's length to claim the gold.
Charline Picon took silver to follow up her win in Rio five years ago.
"It's amazing. I tried so hard in that race - I just kept going and going," said Wilson. "I just want to win, but any medal is amazing. I'm super happy and I just gave it everything I had."
CHINESE TAIPEI WIN MAIDEN BADMINTON GOLD
Lee Yang and Wang Chi-Lin took home Chinese Taipei's first badminton gold on Saturday with a victory over Liu Yu Chen and Li Jun Hui of two-time reigning champions China in the men's doubles final.
Their victory brought up the seventh Olympic gold for Chinese Taipei – the previous six having been split across weightlifting (four) and taekwondo (two).
Malaysia claimed their first medal in Tokyo thanks to Wooi Yik Soh and Aaron Chia triumphing in the bronze medal match.
In total, Malaysia have claimed 12 medals in their Olympic history, but are yet to clinch gold in any event.
