China's Xie Wenjun corsses the finish line during the men's 110m hurdles race at the IAAF Diamond League Athletics in Shanghai, east China, May 18, 2014. (Xinhua/Li Jundong)

SHANGHAI, May 18 -- China's Xie Wenjun stunned a star-studded field（明星云集的领域）, including the top three finishers in Moscow worlds last year, to win the men's 110m hurdles with a personal best of 13.23 seconds at the 2014 Diamond League Shanghai meet here on Sunday.

The 23-year-old Xie improved his personal best to 13.28 and finished third in the last edition of Shanghai meet. On Sunday he further bettered his PB and claimed his first title at the Diamond League stage by leading from the start in front of a jubilant local crowd(在一片欢腾的人群前面的地方).

"Today's result is the payoff from my hard working in the past months. I did not expect that I can finish first in the race because all my rivals are world-class athletes. So it is a great surprise and great pleasure for me to win at home," said the Shanghai-native.Frenchman Pascal Martinot-Lagarde won the silver in 13.26. American hurdler David Oliver, defending world champion and also the winner in Doha meet, took the bronze in 13.30.
