Diamond League: Christine Ohuruogu third in 400m in Doha

Christine Ohuruogu opened her 2013 Diamond League campaign with a third-place finish in the 400m.

Last year's Olympic silver medallist ran a season-best time of 50.53 seconds but was beaten by Amantle Montsho of Botswana and American Allyson Felix.

Olympic bronze medallist Robbie Grabarz finished fourth in the high jump with a clearance of 2.24m.

Analysis

"I was disappointed with Christine - she gave herself too much to do. She just gives herself so much to do over that last 100 metres and it's frustrating, in a way, to watch her run that race."

David Rudisha, who broke the 800m world record in London, was the evening's star attraction and won his 800m race.

The Kenyan was made to work for the victory however, with Mohammed Aman pressuring him on the home straight before Rudisha powered over the line in a time of 1:43.87.

Britons Michael Rimmer (1:44.97) and Andrew Osagie (1:45.41) finished sixth and eighth respectively.

Ohuruogu ensured it was not a barren evening for Great Britain on the track, as the 28-year-old produced a typically strong final 100m to take overhaul Francena McCorory of the US for third place.

But she could make no serious impression on either Olympic 200m champion Felix or world 400m champion Montsho, who won in 49.88 seconds.

"A 53.93 last lap by Hagos Gebrhiwet in the Doha 3,000m may cause a bit of concern for Mo Farah because it means that the Ethiopian teenager is approaching the deadly finishing speed shown by the British number one in his big races. Gebrhiwet's world-leading time of seven minutes and 30.36 seconds was four seconds better than Farah's best for the distance, and he also easily opened up a two-second gap over a strong field headed by Thomas Longosiwa, who collected the Olympic 5,000m bronze last year in London. Could he be the next big Ethiopian distance star?"

Grabarz could not get his Diamond League campaign off to a winning start, failing at 2.27m in an event won by Bohdan Bondarenko of Ukraine with 2.33m. Fellow Briton Samson Oni cleared 2.19m.

Other British athletes fell short too, with Shara Proctor sixth in the women's long jump with a leap of 6.82m and Jack Green failing to finish in the 400m hurdles.

Elsewhere, Tiffany Porter produced a season's best of 12.74 seconds in the women's 100m hurdles to finish fourth behind Dawn Harper-Nelson of the United States, who won in a world-leading time of 12.60 seconds.

In the men's 100m, last year's Doha winner Justin Gatlin held off compatriot Michael Rodgers and Jamaica's Nesta Carter, the American crossing in 9.97 seconds, with Rodgers and Carter 0.02 seconds behind him.

Shelly-Ann Fraser-Pryce of Jamaica (22.48) and Kenya's Asbel Kiprop (3:31.13) took the women's 200m and men's 1500m respectively.
