Diamond League 2013: Christine Ohuruogu finishes third in 400m at Doha curtain-raiser Felix, on the other hand, might not run another 400m this year as she focuses on her specialist 100m and 200m events. Yesterday the American clocked 50.19sec but she appeared to be suffering after going out at a suicidal pace. Olympic high-jump bronze medallist Robbie Grabarz, who consulted sports psychiatrist Steve Peters following a below-par indoor season in an attempt to rediscover the "fun" of competing, will have found little joy with his fourth-place finish yesterday. The 25-year-old, who was crowned overall Diamond League champion last season, managed a clearance of only 2.24m as Ukrainian Bogdan Bondarenko pulled off a surprise victory with a lifetime-best leap of 2.33m that equalled the meeting's record. In a remarkable women's long-jump competition, Britain's Shara Proctor produced a season's best of 6.82m for sixth place but was upstaged by Brittney Reese, the American world and Olympic champion, whose giant leap of 7.25m was the longest by a woman for nine years. Tiffany Porter also found herself in world-class company in the 100m hurdles and her quick time of 12.74sec, another season's best, was good enough only for fourth place. American Olympic silver medallist Dawn Harper-Nelson won in a world-leading 12.60sec. Michael Rimmer wasted no time in securing the 'A" qualifying standard for the World Championships with a time of 1min 44.97sec in finishing sixth in the 800m. Olympic finalist Andrew Osagie was two places further back in 1min 45.51sec. Olympic champion and world record-holder David Rudisha triumphed in 1min 43.87sec, while Ethiopia's Mohammed Aman finished second in 1:44.21.
