World Athletics Championships 2013: Britain's Katarina Johnson-Thompson just misses out on heptathlon bronze Victory went to Ukraine's Ganna Melnichenko with 6,586pts, which will only have added to the frustration of Ennis-Hill, who was forced to pull out of the championships with an Achilles injury. It was the lowest winning score in World Championship history and has been bettered by Ennis-Hill in her last eight heptathlons, stretching back to 2009. Andrew Osagie improved on his eighth-place finish at last summer's Olympics when he finished fifth in the 800m final in a season's best 1 min 44.36 sec. In the absence of the injured David Rudisha, Ethiopian Mohammed Aman took gold in 1-43.31. Mo Farah showed no ill effects from his 10,000m triumph on Saturday when he qualified comfortably from his 5,000m heat to keep alive his hopes of a golden double. "I just wanted to do as little work as possible, freshen my legs up and get ready for the final," said Farah, who coasted home in fifth place in 13min 23.93sec. I did that, so I've just got to recover now and get ready for Friday. He even had time to chat to his American training partner, Galen Rupp, in the final straight as the pair slowed to a gentle jog, with Rupp crossing the line in fourth place and Farah finishing one spot behind him in 13-23.93. "We looked across and with the top five qualifying, we knew were going to do that, so it was about saving as much energy as we could," said Farah. Dai Greene's reign as the world 400m hurdles champion is over after he failed to make it into tomorrow's final, finishing fifth in his semi-final in 49.25sec after an injury-hit build-up. Fellow Britons Rhys Williams and Seb Rodger also failed to progress. But there was better news in the women's 400m hurdles as Perri Shakes-Drayton won her semi-final with ease in 53.92sec, confirming her medal credentials for tomorrow's final, where she will be joined by Scotswoman Eilidh Child. Hannah England, the 2011 world silver medallist, also made it through to the 1500m final by finishing fifth in her semi-final in 4min 6.80sec, though the most eye-catching performance came from American Mary Cain, a training partner of Farah. She qualified for the final at the age of 17. Olympic high jump bronze medallist Robbie Grabarz hinted at a return to form as he made light work of qualifying for tomorrow's final with a leap of 2.29m.
