MOSCOW — So far, the US-Jamaican sprint rivalry is turning into a rout at the World Championships. Shelly-Ann Fraser-Pryce rubbed it in Monday with a winning margin of Bolt-esque proportions in the women's 100 meters. Her hot-pink colored hair slashing in the air behind her, Fraser-Pryce flashed to an early lead and kept on building it before crossing in a world leading 10.71 seconds. She had time to clench her fist as she crossed the line with silver medalist Murielle Ahoure of the Ivory Coast crossed a massive .22 behind. The first American, defending champion Carmelita Jeter of the United States, took bronze in 10.94. Like Usain Bolt, she now has two Olympic and two world titles in the 100. And in Moscow she gave Jamaica a 2-0 lead over the Americans in the sprint duel, showing the Caribbean island produces the fastest runners on the planet. The United States got its part of the glory, too, when David Oliver led a 1-2 finish in the 110 hurdles. It would have been a clean sweep had defending champion Jason Richardson not stumbled near the end. The 31-year-old 2008 Olympic bronze medalist posted the fastest time of the year, 13.00sec, while compatriot Ryan Wilson took silver with 13.13sec and Russian Sergey Shubenkov won the bronze in 13.24sec. In the women's 400, Christine Ohuruogu set a British record to regain the world title she first won in 2007, dipping at the line to cap a great comeback and beat defending champion Amantle Montsho of Botswana by .004 seconds. New Zealand's Valerie Adams won a record fourth women's shot put world title. The 28-year-old two-time Olympic champion threw a best of 20.88 meters while Germany's Christina Schwanitz took silver with a personal best of 20.41m. China's Olympic bronze medalist Gong Lijiao had to settle for third again at a major championships with 19.95m. Germany's Raphael Holzdeppe was a shock winner of the men's pole vault title as he edged red-hot favourite Frenchman Renaud Lavillenie on countback. Both men failed three times to clear 5.96 metres but the German had been faultless in moving up through the heights to notch 5.89 and add world gold to his Olympic bronze last year. Olympic champion Lavillenie, who had dominated the event all season, was uncharacteristically off form and had several failures along the way before settling for silver, also on 5.89.Bjorn Otto of Germany took bronze on countback ahead of American Brad Walker after both men cleared 5.82. James and Merritt set up 400m showdown Grenada's Olympic and world 400 metres gold medalist Kirani James and his predecessor as world and Olympic champion LaShawn Merritt set up a mouthwatering clash in the 400m final after winning their semifinals. James, 20, and Merritt, though, may have to keep an eye out in Tuesday's final in Moscow on fast-improving Saudi Arabian Yousef Ahmed Masrahi. The 25-year-old, who is bidding to give Saudi Arabia only their second ever world championship medal, won his semifinal with a personal best and new national record of 44.61 seconds — the second fastest time of the semifinals. Merritt had served a 21-month doping ban earlier. — Agencies
