Swedish Olympic athlete Armand Duplantis broke his own pole vault world record as the curtain on the 10-day World Championships track and field meet closed in Eugene Sunday.
After the United States claimed emphatic victories in both the men's and women's 4x400 meter relays, Duplantis took center stage and duly delivered a perfect finale for the first championships on American soil.
The Swede sailed over 6.21 meters to surpass his previous mark by 1 centimeter – set in March en route to winning gold at the World Indoor Championships – and complete his collection of medals by claiming a first world title.
"It's great; I cannot complain," Duplantis said. "Actually, I did not think about the record that much today ... I really wanted to win the gold so badly. It was the medal I was missing.
"So when I was on this height, it was like everything came together and it happened from there."
American Chris Nilsen took silver with 5.94 meters on countback from Ernest John Obiena, whose bronze was the first-ever world medal for the Philippines.
Unheralded Nigerian Tobi Amusan had earlier stolen the show in the women's 100-meter hurdles, rocketing to a new world record of 12.12 seconds in the semifinals.
She then won the gold in what was initially announced as a world record 12.06, although excessive wind speeds meant her time was ruled out.
"The goal was to come out and to win this gold ... The world record is a bonus," said Amusan, who finished 0.17 seconds ahead of Jamaican Britany Anderson while Puerto Rico's Olympic champion Jasmine Camacho-Quinn went home with bronze.
American Athing Mu held off British rival Keeley Hodgkinson to add the world 800-meter title to her Olympic crown while Germany's Malaika Mihambo, also a gold medallist in Tokyo, retained her long jump title.
Jakob Ingebrigtsen of Norway made up for this runner-up finish in the 1,500-meter with a convincing victory in the 5,000-meter, where reigning Olympic champion and world record holder Joshua Cheptegei faltered and finished in ninth place.
"I needed it," Ingebrigtsen said. "I felt really good today ... but 5 kilometers is a tough race."
French world record holder Kevin Mayer regained the decathlon title after impressive performances in the pole vault and javelin, seizing opportunity after a competition-ending injury to Olympic champion Damian Warner.
In the morning session, Italy's Massimo Stano claimed a one-second victory over Masatora Kawano of Japan in the men's 35-kilometer race walk, adding a world gold to his Olympic crown.
The United States wrapped up the championships by consolidating its place at the top of the medals table with a championship record of 33 medals.
The men's quartet came home in 2 minutes and 56.17 seconds and strengthened the Americans' stranglehold on the event.
The United States has now won eight of the past nine world titles and eight of the past 10 Olympic golds.
Sydney McLaughlin, the newly crowned 400 meters hurdles gold medallist, anchored the women's team and ran a remarkable 47.91 final leg to give the hosts their 13th gold medal of the event.
