Katarina Johnson-Thompson has work to do to win her first senior global heptathlon medal after slipping to fifth in the standings with one event to go at the World Championships.
Despite a strong showing in the long jump and javelin on Sunday morning, the Liverpudlian lies fifth ahead of the final event tonight - the 800m.
A jump of 6.56m bumped her up to third in the standings after the first of Sunday’s three events, but not even a season’s best javelin throw of 41.72m was enough to stop her falling down the rankings.
She will start tonight’s final event 240 points off the podium, the equivalent to around 17s on the track.
Elsewhere on Sunday morning in the London Stadium there was progress through to semi-finals for both Jack Green and Andrew Pozzi.
The Olympians made differing routes through their heats, with Green having to rely on a fastest loser spot in the 400m hurdles, while Pozzi won his 110m hurdles heat in style.
Green ran 49.55s and had looked comfortable, until clipping the eighth of ten hurdles, and in the end was just relieved to make it through.
“I was running really well and I just wore a hurdle - welcome to 400m hurdles,” he joked.
“It took absolutely everything just to keep that stride into the last two, which tend to be my best hurdles, so it shows that someone who normally strong finishes like I do, when you mess up number eight, it doesn’t really matter.
“I’ve learned that I’m in really good shape, I’m in maybe a little too good shape, that’s why I hit it, because I was getting too close, which I’ve never had before.
“But that’s a nice positive, I’d rather be too close and know that I can run faster, rather than stretching and messing it up in that way.”
Pozzi clocked 13.28s to win his heat and set the fourth fastest time of the morning, with the 25-year-old returning to the London Stadium for the semi-finals later on Sunday evening.
“That's all it takes in round one, I just knew I didn't have to do anything stupid,” he said. “I knew I had gone out well so I just want to make sure I was clean over the barriers in the second half of the race.”
Pozzi’s compatriots David Omoregie and David King will not be returning for the semi-finals, though, after missing out in the heats.
But there was further British success in the women’s 400m with Scotland’s Zoey Clark qualifying for tomorrow’s semi-finals after finishing third in her heat.
A time of 51.88s was good enough for third in her heat, but Emily Diamond and Anyika Onuora both failed to qualify from their races.
“It’s a bit difficult to prepare for that because it’s so amazing, such a good atmosphere,” said Clark.
“In the warmup I heard all the cheering for everyone else, so I had an indication of what it was going to be like, I just had to enjoy it rather than let it intimidate me.
“I knew it was going to be tough, but I knew I didn’t want to change my game-plan too much.
“I just went out fast over the first bit, stayed nice and steady then and made sure I had enough left in the home straight to give it a kick.”
The first event of the day saw the 3000m steeplechase runners take to the track, but none of the three British representatives had what it took to make the final as Zak Seddon, Ieuan Thomas and Rob Mullet all missed out on qualification.
