Team GB discus finalist Lawrence Okoye missed out on a medal after a throw of 61.03m to end the competition in 12th place.
The 20-year-old had produced a throw of 65.28 metres in qualifying.
The former rugby player, who has deferred a place at Oxford to study law to concentrate on athletics, was appearing in his first major championship in his home town.
And despite huge support from the crowd, he could not not build on his opening effort, following with a foul and then 60.11m to miss the top-eight cut.
He said: "I think I was trying a bit too hard today but it's come and gone now and I have to move on. I didn't anticipate coming last in the final.
"It's been a good couple of years. Obviously it's ended in failure, but I gave it my all, maybe a bit too much.
"I felt more relaxed than yesterday and ready to throw far. I was trying too hard, it's something I've got to learn."
Asked about his future, he said: "I don't know, I'm going to have to wait and see. I've got some decisions to make. Obviously this is very disappointing, now I've got to think about my future."
