Bay of Plenty sprinter Joseph Millar is out of the World Championships after failing to qualify from his 200 metre heat in London.
The New Zealand sprint champion was drawn in lane two in the sixth of seven heats where the first three and next three fastest advanced to the semi-finals.
Millar started well but could not hold on down the straight finishing sixth in 20.97 in a heat won by Isiah Young of USA in 20.19.
Earlier in the competition, Millar finished fifth in his heat of the 100 metres, also failing to advance through to the semi-finals.
Miller had clocked 20.37 in winning the New Zealand 200 metre title in March and said that he felt very tired.
"I'm not too sure whether it is a result of racing the 100m. The last couple of days I've struggled with a bit of sleep.
"I felt really good today warming up, a little bit tired but put that down as a bit of nerves."
"I'm not quite sure what really happened out there today, just didn't feel like I was myself," said Millar.
Millar said racing in the Northern Hemisphere takes some adjustment.
"It's a dream come true to come and race here, obviously it's a difficult turn around to come from a New Zealand summer."
"I'm still finding my feet and figuring out how to train to come to one of these and perform, I guess I've figured out one way not to, but I'm still learning and the Commonwealth Games they are going to have to come into our turf so we'll see how they handle it."
"I've still got more to come with world uni's in the next couple of weeks. I'm a little bit disappointed in myself but it's just part of the experience," he added.
