EUGENE - 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 medallists from last month's World Championships in Budapest to be disappointed in Eugene, Oregon, on Saturday, as 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 after winning in the same time at the Xiamen Diamond League on September 2.
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 break out of that group and 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.
Disappointed not to win, he was nevertheless satisfied with his second-fastest time of the year and a chance to race one more time in front of home fans after his gold treble in Budapest.
"After a World Championship win, I know that's what they really wanted to see," he said. "I was able to do a victory lap, even though I didn't win the victory, but they were just as excited."
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.
