Ian Thorpe has once again missed out on the final of a 100m freestyle event after finishing 12th fastest in the heats of the World Cup meet in Tokyo.
The five-time Olympic champion missed the final of the 100m freestyle in Beijing five days ago and, despite improving by 0.76 of a second, was unable to force his way into the top eight times.
Australian head coach Leigh Nugent said the 49.45s time could still be seen as positive in Thorpe's comeback, highlighting his ability to improve quickly.
"He dropped nearly a second in his final 50m from Beijing," Nugent said.
"The time drop was a significant leap for Ian and that swim shows the sort of improvements that he can make."
