Good start for Johnson-Thompson
Katarina Johnson-Thompson got her World Championships off to a promising start in the heptathlon in Moscow on Monday morning.
Latest news from Monday's action at the World Athletics Championships in Moscow.
The 20-year-old clocked 13.49 seconds in the 100 metres hurdles, just 0.01secs outside her personal best, to lie seventh after the first event with 1052 points.
Johnson-Thompson had said in the build-up she felt under no pressure, despite the withdrawal of Olympic champion Ennis-Hill leaving her in the spotlight.
She claimed experiencing London 2012 as a teenager had prepared her for anything.
This morning, beneath overcast skies at the Luzhniki Stadium, was a little different.
The Liverpool athlete was bowled over by the noise which greeted her introduction to the crowd last summer, mouthing "wow" as she smiled the biggest grin in the stadium.
This morning there were barely 500 spectators in the arena to watch her.
Meanwhile, Dai Greene's lack of fitness was clear as he began the defence of his world 400 metres title by struggling through his heat.
The Welshman admitted ahead of the championships that he had endured a "really depressing last few weeks", with a calf tear forcing him out of his last two races and severely hampering his training.
He accepted he would be stepping into the unknown in the Russian capital, and could only manage fourth as he booked his semi-final place this morning.
He actually came home fifth, which would have left him relying on a fastest loser spot, but moved up a place when Puerto Rico's Eric Alejandro was disqualified.
The 27-year-old, who is far from the form which fired him to World Championship gold in Daegu two years ago, faded down the home straight to come home in 49.79 seconds.
Greene, fourth at London 2012, has endured a torrid season following a double hernia operation in March and a virus which led to him suffering his first defeat by a fellow Briton in five years
He was the 15th-fastest qualifier, American Olympic silver medallist Michael Tinsley heading the pile with 49.07secs.
And the Welsh athlete revealed that, to add to his injury worries, he had been ill over the weekend.
Greene said: "I've had a tough few weeks. I've not been able to do as much hurdling and it showed a bit at the end.
"I was ill on Friday and Saturday, so it's been a nightmare few days to be honest. I came down with some fever on Friday night and I've just been trying to eat and drink as much as I can to get my energy up.
"We were wondering if I'd be good enough to run today. We didn't know what I was capable of.
"We've got the answer and it's not the kind of answer we like. But hopefully I'll be a bit better tomorrow. I've had this situation before where you do one race and then feel a lot better the next day as a result of it. Fingers crossed I can rest up enough and put in a better performance tomorrow.
"The calf's been good. I hurdled on Friday for the first time, only over half a dozen hurdles, but that's all we wanted to do. We don't want to risk it, just to get the confidence it was working again.
"If I feel like this tomorrow then realistically I'll have no chance of getting a medal, but I hope I'll feel better.
All the Britons progressed from their heats, with European champion Rhys Williams also far from impressive in finishing fourth in 49.85s.
Sebastian Rodger, making his senior debut was the quickest of the trio in 49.66, even if his fifth-placed finish meant he went through as a fastest loser.
Perri Shakes-Drayton demonstrated her medal credentials in the women's 400m hurdles with a confident run, pulling comfortably clear of defending champion Lashinda Demus of the United States and Russia's Olympic gold medallist Natalya Antyukh.
The Londoner won her heat in 54.42 to progress as easily the fastest qualifier.
But her rival for the gold, Czech Zuzana Hejnova, also looked impressive, able to slow to a jog metres from the line such was her lead to win in 55.25.
Shakes-Drayton is aiming to make up for the agony on missing out on a place in the Olympic final in her home city by following in the footsteps of Sally Gunnell and taking the world crown.
She said: "It felt good, it was relief - I'm through without anything happening. I knew I was more than capable of making it through, but it's just pure relief.
"I just need to rest and recover properly and tomorrow's another day."
Scotland's Eilidh Child, also enjoying the season of her life, went through to the semi-finals after finishing second in her heat in 55.17, and Meghan Beesley made it a full contingent in the next round by also coming second in 55.45.
