BEJING, March 15 -- China's world champion He Zi stumbled on her third dive and surrendered the women's 3m springboard title to teammate Wang Han while Olympic and world champion He Chong won the men's 3m springboard on the second day of the FINA/NVC Diving World Series 2014 at the National Aquatic Center (Water Cube) here on Saturday.

He Zi, winner at the Barcelona world championships, led the first two rounds but lost her balance on her third dive 305C, which earned only 49.50 points.

Wang Han, bronze medalist in the 1m event at the Barcelona worlds, displayed consistent form throughout to win with a total score of 368.55 points. He Zi finished second in 356.40 and Pamela Ware of Canada came third in 339.75.

"I didn't expect to have such a bad start in my third dive. I tried to adjust my body after I felt my feet slipped out of the springboard, but failed," said He Zi. "It is a lesson for me that I need to keep focused during the competition all along."

It was Wang Han's first victory over He Zi in big events. "I am happy with the gold, but I can not dance or sing for my victory because I had some minor mistakes during the competition. I hope I can do better and go further in the future events," said Wang.

A mistake in the reverse 307C did not spoil He Chong's bid for a gold in the men's 3m springboard. He scored only 73.50 points for his third dive but came back strongly in the last two rounds to amass a winning total of 528.80 points.

China's synchro platform Olympic champion Lin Yue made his springboard debut and placed second with 494.95 while Illya Kvasha of Ukraine had bronze in 484.80, edging Evgeny Kuznetsov of Russia by 0.80.

"I had ups and downs during today's semifinal and final. I felt rusty in the competition and since I am getting elder, it's hard to recover from injury," He Chong said.

Kvasha was happy with his bronze medal after a close battle with Kuznetsov. "It's good that I finally got the medal. It is highest level of competition so far this year. I think I will get better after more events before the most important events in this year -- the World Cup and the European Championships in July and August," Kvasha said.

The 2014 FINA/NVC Diving World Series Beijing stop will come to the end on March 16 after the men's and women's 10m platform finals.
