COCA-Cola Games record holder Batinisavu Uluiyata failed to live up to expectations at the World Junior Athletics Championship in Eugene, Oregon, US.
Competing in the 400 metres event, the Natabua High School athlete failed to qualify for the semi-finals from the heats.
Uluiyata was placed in heat one of the competition on Tuesday and finished fifth in a time of 47.95 seconds.
The time was slower than what he clocked at the Oceania Athletics Championships to qualify for the world meet.
At the Oceania event, Uluiyata clocked 47.67s, which was within the 47.70s qualifying time.
He first represented the nation at the 2013 World Youth Championships in Ukraine and the Pacific Mini Games in Wallis and Futuna.
Uluiyata won gold medals during the Cola-Cola Games intermediate 200m and 400m events.
