Olympic 110m hurdles champion Aries Merritt’s last race before Moscow did not go to plan either, with the world record holder coming to a premature halt after clipping the fifth hurdle.
“I’m thankful I’m not injured,” he said as he sheepishly waved to the crowd.
Olympic 400m hurdles champion Felix Sanchez, who 12 months ago shed tears on the podium after regaining his title at the age of 34, also cut a frustrated figure as the Dominican trailed home last in a race won by the US’ Michael Tinsley, who Sanchez beat into silver in London.
“I’ve been playing around with different strategies this year, but that one was an absolute disaster,” Sanchez said.
Olympic heptathlon champion Ennis-Hill offered few clues as to whether she will be fit to compete in Moscow after putting her injured Achilles tendon to the test.
Ennis-Hill, with the lower half of her left leg heavily taped, appeared to run well within herself in the hurdles, showing no outwards signs of discomfort as she took fourth in 13.08.
She then competed in the long jump before telling reporters: “I’m frustrated, I need to speak to my coach and have a think. I’m running out of time a bit.”
