SHANGHAI — Jamaica dominated the sprint races at the Diamond League meet in Shanghai Saturday, with Shelly-Ann Fraser-Pryce winning the women's 100 meters and Warren Weir capturing gold in the men's 200. Fraser-Pryce, a two-time Olympic champ, ran 10.93 seconds to beat Blessing Okagbare and defending world champion Carmelita Jeter, who pulled up at the finish with an apparent leg injury. Jeter fell to the track after the race and lay on her back for several seconds before being carried off on a stretcher. Meet organizers said the American would undergo tests to determine the nature of the injury. Fraser-Pryce is off to a strong start this year. She also won the 200 in the season-opening Diamond League meet last week in Doha. Weir, the bronze medalist at the London Olympics, finished in 20.18 seconds to hold off Justin Gatlin and Jason Young in the final few strides. The field was weakened by the withdrawal of Olympic silver medalist Yohan Blake because of injury. Usain Bolt is also taking a break from the 200 to focus on the 100. Chinese sprint hope Zhang Peimeng broke the national 200 meters record just weeks after he ran China's fastest 100, but failed to trouble the leaders as Olympic bronze medalist Weir pipped Gatlin. “It's not a surprise for me to break the national record since I have already proved myself in the 100. I feel I still have room to improve and I can do better next time,” Zhang said. American Jason Richardson took gold in the 110 hurdles, crossing in 13.23 to edge Ryan Wilson and Xie Wenjun at the line. Olympic champion Aries Merritt pulled up before the first hurdle with what he later said was a leg cramp. Olympic champion Kirani James of Grenada extended his dominance in the 400, comfortably beating American Leshawn Merritt in a time of 44.02. Asbel Kiprop of Kenya outsprinted Mekonnen Gebremedhin down the final stretch to win the men's 1,500, lunging across the finish line in 3:32.39, just .4 seconds ahead of the Ethiopian. Ethiopian Genzebe Dibaba outpaced Olympic champion and compatriot Meseret Defar in the women's 5,000 meters. Defar snatched Olympic gold in London from Genzebe's sister Tirunesh. Russian world record holder Yelena Isinbayeva won the women's pole vault with a mark of 4.70, before falling short on two attempts to reach 4.85. Meanwhile, British golden boy Greg Rutherford, who took gold in the long jump at the London Olympics had to settle for third behind China's Li Jinzhe's world leading distance of 8.34 meters. — Agencies
