"I competed in the synchro springboard and now synchro platform at the worlds. I need to get used to different events, different partners and different feeling in the air. I made mistakes in the entry tonight and did not come up to my goal -- to dive as perfect as possible," said Cao who will compete 3m springboard on July 17.

"We talked about our target before the final that we hoped to get points over 500+. We were very close to that. So next time we should set our goal higher than that, and therefore we may have better results. It was the best performance I did this year. We were lucky that we made the team through our three-leg national Olympic trials," Chen Aisend said.
