In a convincing victory over Kenny Bednarek and Erriyon Knighton, Noah Lyles successfully defended his 200-meter world championship. He also broke Michael Johnson's 26-year-old national record.
Lyles and 18-year-old phenom Knighton were expected to face off in the race, but Lyles was in a league of his own, running a remarkable bend and winning in 19.31 seconds.
His time beats the American icon Johnson's mark from the 1996 Atlanta Olympics by a tenth of a second. It places Lyles behind Usain Bolt, whose world record is 19.19, and fellow Jamaican Yohan Blake as the third fastest man in history.
However, the manner of Lyles' win was just as captivating as the numbers. The 25-year-old fired up the Eugene fans before the race, leaving Bednarek and Knighton in his trail. He then walked around the track with his race suit shredded in excitement and his gold medal raised to accept the accolades.
Olympic silver medalist Bednarek came in second place in 19.77, followed by Knighton in 19.80. After Fred Kerley's victory in the 100 metres earlier in the week, which also provided an American 1-2-3, it completes the US sweep in the men's sprints.
The race served as the seventh day of action's highly anticipated grand finale. Apparently previously close friends, Lyles and Knighton last month came into contact while travelling on the same railway.
When Lyles defeated Knighton in the US Trials in June, he pointed across Knighton at the time. After stating "it ain't finished," Knighton left their joint post-race interview.
While Knighton, who ran 19.49 earlier this year, appeared to fear the big moment, Lyles flourished in it. I put no strain on myself, Lyles told BBC Sport. "I came out here to give it everything I had.
"Once I received the start I sought, that time was certain to arrive. "I recall the Americans sweeping everything when my dad [world 4x400m relay gold medalist Kevin Lyles] was battling against Michael Johnson back then.
"After that, we had to watch the Jamaicans rule. When I got there, I told myself, "I want to make sure the USA is dominating again."
