Perri Shakes-Drayton and Eilidh Child both eased through to the final of the women’s 400m hurdles at the World Championships in Moscow.
British champion Shakes-Drayton clocked 53.92 seconds, the second quickest qualifying time of the semi-finals.
But Dai Greene’s defence of his 400m hurdles world title ended with a fifth-place finish in his semi-final.
The Briton, who has suffered injury and illness in recent months, struggled home in 49.25 seconds.
“I just didn’t have it in the tank,” admitted the 27-year-old Welshman.
Greene’s failure to make an impact in the Russian capital is of little surprise because he was blighted by an Achilles tendon problem in the run-up to the championships and had to overcome illness prior to his heats.
“Things were going well up until the last few weeks. This championship came a week too early – maybe another week and I would have been able to get up there,” added the Swansea Harrier.
His compatriot Rhys Williams also failed to progress, a fourth place in 49.29 was the best he could manage, while fellow Briton Sebastian Rodger was sixth (49.32) in the first semi-final.
At the other end of the spectrum, Shakes-Drayton has performed like a potential medallist throughout the season and looked strong as she overtook defending champion Lashinda Demus on the home straight.
“I feel good,” she said. “I would love to come home with some kind of bling but we won’t say too much, we will just wait and see.”—BBC
