Daley's new personal best would have secured him gold in the Beijing final
Olympic diving champion Matthew Mitcham expects British youngster Tom Daley to emerge as a serious rival in the build-up to the 2012 Games.
"Tom's a huge threat. He's a phenomenal diver - not just for his age, but in his own right," Mitcham told BBC Sport.
"He is going to be huge competition in Sheffield, in the Commonwealth Games, through to London and beyond."
The pair, along with Chinese star Luxin Zhou, compete in the third round of the World Series in Sheffield this weekend.
Daley, 14, finished seventh behind Mitcham and Zhou in the Beijing pool last summer, but showed he is still improving on his prodigious talent with a personal best of 540.70 in the World Series in Changzhou last month.
