Eilidh Doyle posted a world-leading time as she claimed gold in the 400 metres hurdles at the IAAF Diamond League meeting in Doha.

The 29-year-old Scot triumphed in 54.53 seconds at what is the first Diamond League event of 2016.

Doyle, formerly known as Eilidh Child, is the reigning 400m hurdles European champion and looking to compete at her second Olympics this summer in Rio.

Quoted on doha.diamondleague.com, she said: "I am very happy with my race. My training worked really well, although my reaction was a bit slow in the start.

"Obviously my focus is on Rio -- I will just have to try harder and harder."

Doyle, who failed to make the final at London 2012, finished ahead of second-placed Kemi Adekoya of Bahrain, with Jamaica's Commonwealth champion Kaliese Spencer coming third.

Caster Semenya was among a host of winners setting world-leading times and distances in Doha. The South African claimed gold in the women's 800 metres in one minute 58.26 seconds.

It was a first Diamond League race victory since 2011 for Semenya, who was forced to undergo gender testing after becoming 800m world champion in 2009 then went on to take silver in the event at the London 2012 Olympics.

In the women's 100m, American Tori Bowie ran a world-leading 10.80 seconds, while her two closest rivals also achieved times under the previous fastest of the year, with second-placed Dafne Schippers of Holland clocking 10.83 seconds and Jamaica's Veronica Campbell-Brown 10.91 seconds in third.

The men's 110m hurdles saw Campbell-Brown's compatriot Omar McLeod improve his own world-leading time from 13.08s to 13.05s.

Another track highlight was Ethiopia's Almaz Ayana running the fastest time of 2016 in the women's 3000m [eight minutes 23.11 seconds].

Kenya's men's 1500m world champion Asbel Kiprop won that event in a world-leading three minutes 32.15 seconds, while there were also track victories for Ameer Webb in the men's 200m and fellow American LaShawn Merritt in the 400m race.

Meanwhile, the triple jump events saw world-leading marks set by American world and Olympic champion Christian Taylor in the men's competition -- 17.23m, beating his own previous mark -- and Colombia's Caterine Ibarguen in the women's [15.04m].

Meanwhile, Great Britain's Nekoda Davis and Ashley McKenzie both picked up medals at the Baku Grand Slam.

Davis claimed silver -- the second Grand Slam medal of her career -- after defeat in the women's -57kg final to Japan's Tsukasa Yoshida, with her efforts over the day securing her another 300 qualifying points for the Rio Olympics.

McKenzie added 200 points to his qualifying total as he took bronze with victory over Mongolian Amartuvshin Dashdavaa in the men's -60kg category.
