American Christian Coleman edged world champion and fellow countryman Noah Lyles in the 100 metres at the season-ending Prefontaine Classic.

Coleman won in 9.83 seconds on Saturday, matching Lyles' world best this season, with Lyles finishing in 9.85. Coleman roared after his time became official and slapped the hand of a cheering fan at Eugene's Hayward Field.

The annual Prefontaine Classic, normally run earlier in the year, served as the Diamond League finale this season.

Lyles won gold medals in the 100, 200 and 4x100 relay at the World Championships in Budapest last month. He was treating the Prefontaine as something of a victory lap in his own country.

After Saturday's race, he celebrated with a salted caramel milkshake.

"I gotta come bring it back home," Lyles said about running one final race this year on American soil.

Joining Coleman and Lyles in the star-studded event was sprinter Sha'Carri Richardson, who won gold medals in the 100 metres and the 100 relay, and the bronze in the 200, in Budapest.

Richardson is in the midst of a comeback in the run-up to the Paris Olympics next summer, after she was denied a chance to run in the Tokyo Games because of a positive drug test for marijuana.

She ran a world-best time this season of 10.65 in Budapest but on Saturday she finished fourth in 10.80. Jamaican Shericka Jackson, the second-place finisher at the worlds, won the 100 in 10.70.

"I want people to understand, it is not related to just winning," Richardson said about her resurgence.

"I'm having fun because I'm embedded within my spirit, within my mind, and within my community that I created for myself. So that's the happiness that you guys see."

Jakob Ingebrigtsen of Norway won the Bowerman Mile in an American record 3:43.73. It was also a Diamond League record. American Rai Benjamin won the 400-metre hurdles in a Diamond League and meet record 46.39.
