EUGENE, Oregon: Olympic double bronze medallist Walter Dix will have a chance to race Usain Bolt twice in August's World Championships after winning the 200 meters at the American trials Sunday. The victory, in a wind-assisted 19.95 seconds, completed a sprint double for Dix, who won bronze medals in the 100 and 200 metres at the 2008 Olympics where Jamaican Bolt swept to world records in both. “I can't really see myself losing,” Dix said of the upcoming world championships in Daegu, South Korea. “Usain Bolt, Asafa Powell, whoever is there I am going to give them a good shot,” Dix said. “I am confident I can win the gold after what I did today.” Dix, who won the US 100m title Friday, became the first to claim both national championships since Tyson Gay in 2007. The wins came with little speed training, Dix said, and he promised to run faster as the season progresses. “To come out here and run under 10 seconds (in the 100) and under 20 in the 200 is truly a blessing,” he added. Doc Patton was a close second in 19.98 with Jeremy Dodson claiming the third spot on the US team for the world meet. Shalonda Solomon ran down favorite Carmelita Jeter for a shock victory in the women's 200m. Solomon finished in 22.15 seconds, the year's fastest time, to defeat US 100 meters champion Jeter by eight hundredths of a second. Jeneba Tarmoh took third in 22.28. “I know if I can run with Carmelita, I can run with anybody,” said Solomon. World 400 meters champion Sanya Richards-Ross finished seventh, ending her chances of running a 200-400 double at the world championships. Three other 2011 world-leading performances came on the sun-splashed concluding day of the trials. Kellie Wells topped a world-class 100 meters hurdles field in 12.50 seconds, outrunning Danielle Carruthers and Olympic champion Dawn Harper. Carruthers finished in 12.59 with Harper clocking 12.65. Lolo Jones's run of bad luck continued when she failed to advance past the semifinals after a poor start and then hitting arms with competitors. The US demonstrated its jump power with both world long jump champion Brittney Reese and high jumper Jesse Williams delivering 2011 bests. Reese became the year's first women's longer jumper to exceed seven meters as she leaped 7.19. Williams soared to a lifetime best on his final try at 2.37 meters. Only two Americans have ever jumped higher outdoors. Adam Nelson, the 2005 world shot put champion, came close to another season leader with a heave of 22.09 meters to pace a powerhouse US team for the event. Olympic silver medallist and reigning world champion Christian Cantwell took second at 21.87 meters while 2007 world champion Reese Hoffa threw 21.86m to complete the team. Olympic silver medallist Jenn Suhr had a streak of five US championships snapped when she finished second to Kylie Hutson in the women's pole vault. Another 2008 silver medallist, Hyleas Fountain, finished sixth in the heptathlon after suffering from food poisoning. Her world championship status remained up in the air. In the men's 400 hurdles, a leaning, stumbling Jeshua Anderson won a blanket finish. The extra effort gave the US collegiate champion the victory over Olympic bronze medallist Bershawn Jackson. Both were timed in 47.93 seconds. Twice Olympic champion Angelo Taylor claimed the third US team spot in 47.94.
