JAKARTA, Aug 30 — China’s powerhouse divers secured a one-two in the women’s 10 metre platform today, with Si Yajie taking gold to successfully defend her Asian Games title.

Nineteen-year-old Si, an Olympic silver medallist, never looked seriously threatened by Zhang Jiaqi, 14 — but later claimed she had not anticipated the win over her younger rival.

"I’m feeling quite emotional, I did not expect this,” Si said after securing the top spot with 405.45.

Zhang — nicknamed "Little Fu Mingzia” after the Chinese diving great — opened with an outstanding forward three-and-a-half somersaults in front of a sea of boisterous, red-shirted China fans.

But in the end Si’s experience saw her through and she won with a remarkably consistent 8.5 average on all five rounds.

"I felt the pressure a little bit,” said the tiny Zhang, looking overwhelmed among a scrum of reporters.

"But she (Si) is a bit older and has taught me how to cope,” added Zhang, who won the synchronised 10 metre platform on Tuesday with Zhang Minjie, who was celebrating her 14th birthday.
