Tyson Gay recorded the worst result since the end of his doping ban, finishing last in a 100m race in Zurich on Thursday.
Gay, who owns the American record of 9.69 seconds, clocked 10.35 at the Swiss Diamond League meet. Gay started out slow, swayed in his lane and eventually decelerated once it was clear he wouldn’t finish among the leaders. He had run 9.93 and 10.04 in his first two races since his ban was lifted in July.
Jamaican Kemar Bailey-Cole won in 9.96 in Zurich. Former world record holder Asafa Powell was fourth in 10.07. Powell ran 9.87 on Saturday, making him the fastest Jamaican this year.
Usain Bolt ran two 100m races this year, the fastest being 9.98, and shut down his abbreviated season delayed by a foot injury that required surgery and crutches.
The fastest man in the world this year is Justin Gatlin, who has clocked 9.80 seconds but wasn’t invited to the Zurich meet.
Zurich marked the first of two Diamond League finals meets, though the men’s 100m final is in the latter meet in Brussels on Sept. 5.
In Zurich finals events, Jenny Simpson recorded one of the closest wins, by .01 over countrywoman Shannon Rowbury in the 1500m. Simpson, the 2011 World champion, captured the season-long Diamond League title in the event.
Beijing Olympic champion Dawn Harper-Nelson also prevailed in Zurich, in 12.58, to claim the season title in the 100m hurdles. Her top competition, Queen Harrison, fell to the track.
Jamaican Veronica Campbell-Brown won the women’s 100m in a photo finish over Ivorian Murielle Ahoure. They both finished in 11.04. Allyson Felix was seventh in 11.27. Campbell-Brown earned the season title with world leader Tori Bowie sitting out due to injury.
David Rudisha could not summon enough of a late surge in the 800m, settling for third place behind Nijel Amos. Amos clocked 1:43.77, with Rudisha crossing in 1:43.96.
Amos won the 800m season title over Rudisha, who had won 26 straight races from 2009 to 2011 and the Olympics in a world record in 2012 before suffering a knee injury in 2013 that kept him out for over one year.
London Olympic champion Christian Taylor stole the triple jump season title from Olympic silver medalist Will Claye on his final jump. Taylor leaped 17.51m, his farthest this year.
Kenyan Caleb Ndiku won the 5000m and the season title, clocking 13:07.01. American Galen Rupp was third in 13:07.82.
Fabiana Murer cemented herself as Brazil’s top track and field athlete going into 2015, winning the pole vault and the season title with a 4.72m clearance. She defeated a field that included Olympic champion Jenn Suhr.
Olympic bronze medalist Reese Hoffa won the shot put with a 21.88m throw, wrapping up the Diamond League season title.
Michael Tinsley, the Olympic and World silver medalist, finished second in the 400m hurdles, .06 behind South African Cornel Fredericks. It was good enough to earn Tinsley the season title over Puerto Rican Javier Culson.
LaShawn Merritt, who had already clinched the season title in the 400m, won his race anyway in 44.36 without rival Kirani James in the field.
