Usain Bolt wins 200m season finale

Usain Bolt once again blew away the field to win the men’s 200-metre race at Thursday’s Diamond League meet in Switzerland.

The triple gold medallist from the London Olympics ran a meet-record 19.66 seconds on a wet track in chilly Zurich to lead a Jamaican sweep of the top four spots in the final Diamond League 200m event of the season.

Bolt finished second in the standings due to his light schedule, which saw him enter only two Diamond League 200m events this season. He also won last week’s race in Lausanne.

Jamaica’s Nickel Ashmeade captured the Diamond League title after his second-place finish on Thursday.

Bolt will end his season with next week's 100m race in Brussels.

In other notable events Thursday:

Men’s 100m

Olympic silver medallist Yohan Blake won the men’s 100m in a meet-record 9.79 seconds.

The Jamaican, who last week became the third man in history to run a 9.69, defeated countryman Nesta Carter and American Ryan Bailey. Tyson Gay of the U.S. was disqualified for a false start.

Men’s 800m

Mohammed Aman upset Olympic champion and world record holder David Rudisha to win the men’s 800 metres in 1:42.53. Rudisha, who ran a world record 1:40.91 in his gold-medal victory in London, clocked 1:42.81 to finish second.

Aman’s victory clinched the Diamond League season title for the Ethiopian.

Women’s 100m

Olympic champion Shelly-Ann Fraser-Price of Jamaica wrapped up a title of her own by winning the final women’s 100m race of the year, easily defeating Olympic silver medallist Carmelina Jeter and Allyson Felix of the U.S.

Women’s 100m hurdles

Dawn Harper won the Diamond race in the women’s 100m hurdles by leading a U.S. sweep of the top four spots in Thursday’s finale.

Former Diamond League champ Priscilla Lopes-Schliep was fifth, followed by fellow Canadians Jessica Zelinka in sixth and Phylicia George in eighth.

Women’s 1,500m

Ethiopia’s Abeba Aregawi capped her diamond-winning season with a victory in the women’s 1,500. Canada’s Hilary Stellingwerff finished ninth in the race, and pace-setter Diane Cummins did not finish.

Men’s shot put

The men's shot put season finale was held on Wednesday, and defending Diamond League champion Dylan Armstrong of Kamloops, B.C., finished fourth, behind Americans Reese Hoffa and Ryan Whitting and Polish Olympic gold medallist Tomasz Majewski.

Hoffa captured the season title by a wide margin, while Majewski finished second and Armstrong third.
