EUGENE, Oregon -- American Christian Coleman and Jamaica's Shericka Jackson won the men's and women's 100m at the Diamond League finals on Saturday as Noah Lyles and Sha'Carri Richardson were denied.
Lyles and Richardson weren't the only gold medalists from last month's World Championships in Budapest to be disappointed in Eugene, Oregon, where American Rai Benjamin stunned world and Olympic champion Karsten Warholm in the 400m hurdles.
Coleman, the world champion in 2019 who finished a disappointing fifth in Budapest, matched the season's best time of 9.83sec for the second time in two weeks as he followed up his Xiamen Diamond League win.
He is one of three men to post that time this year, along with Britain's Zharnel Hughes and Lyles -- who was unable to make good on his desire to finish his outstanding season with the outright best time of the year.
Lyles, who won 100m and 200m gold in Budapest, was second in 9.85sec and Ferdinand Omanyala of Kenya was third in the same time.
After a false start saw Ackeem Blake of Jamaica disqualified, Coleman got off to a solid if unspectacular start.
He powered through the middle stages and had enough to hold off the charging Lyles and Omanyala.
"In races like that I usually might get tight or just not execute the back end, but I was able to just find a sense of confidence and believe in myself, like I knew I was supposed to win this race and so I was able to stay composed and put out a win at the end," Coleman said.
Lyles, exhausted after his 200m Diamond League win in Zurich, had considered opting out of the season finale, but said he was happy he raced in front of home fans after his gold treble in Budapest.
"I was able to do a victory lap, even though I didn't win the victory, but they were just as excited," he said.
Jackson grabbed the first leg of what she hopes is a sprint double in Eugene, powering to victory in 10.70sec.
The 29-year-old Jamaican is due back on the Hayward Field track on Sunday when she'll try one more time for the 200m world record set by Florence Griffith-Joyner in 1988.
Marie-Josee Ta Lou of Ivory Coast was second on 10.75 and Jamaica's Elaine Thompson-Herah was third in 10.79.
Richardson, doomed by a poor start, clocked 10.80.
Benjamin, disappointed with bronze in Budapest, pulled off a stunner, clocking a Diamond League record -- and the fourth-fastest 400 hurdles time ever -- of 46.39.
He closed the gap on Warholm over the final two hurdles and surged past in the final strides, the Norwegian finishing second in 46.53sec.
"Went back to my old race model, because my second half is just amazing," Benjamin said of the key to the win. "Just tried to channel that today and I feel like I did a really good job," he said.
Warholm acknowledged that despite his end-of-season fatigue he was "pissed off" at losing.
"Over the last hurdle I was feeling good," he said. "I thought I had it, but when he comes to the side you know that he's gonna pass you because he has higher speed over the last hurdle."
- Kipyegon dominates -
Other world champions fared better.
Kenyan Faith Kipyegon remained unbeaten at 1,500m this year, posting a dominant victory in 3min 50.72sec.
Kipyegon, who won the 2022 world title on the same Hayward Field track and retained her title in Budapest as part of an historic 1,500-5,000 double, was barely challenged, with world silver medalist Diribe Welteji finishing second in 3:53.93 and Olympic silver medalist Laura Muir third in 3:55.16.
Winfred Mutile Yavi of Bahrain won the 3,000m steeplechase in sensational style, clocking the second-fastest time ever of 8:50.66 for a decisive win over world record-holder Beatrice Chepkoech (8:51.67).
World champion Haruka Kitaguchi of Japan won the women's javelin with a throw of 63.78m and Venezuela's four-time women's triple-jump world champion Yulimar Rojas won with a world-leading 15.35m.
The women's pole vault showdown between co-world champions Katie Moon and Nina Kennedy fizzled. America's Moon won with height of 4.86m while Kennedy was fifth at 4.56.
Norway's Jakob Ingebrigtsen threatened the mile world record, winning in 3:43.73, just six-tenths outside the world record set by Hicham el Guerrouj in 1999.
