Ivory Williams sprinted to the year's fastest 60m as he clocked 6.49 seconds at the US World Indoor Championships trials Sunday. The victory was the third in a row on the American indoor circuit for the 24-year-old, who had never previously made a US international team at the senior level. “I never would have thought I would have run 6.49, but it happened,” said the 2004 world junior champion who stamped himself as a major contender for the sprint title at the March 12-14 IAAF World Indoor Championships in Doha, Qatar. His time, a personal best, was one hundredth of a second faster than the previous best time for the year set by Briton Dwain Chambers. Former US indoor champion Mike Rodgers was second in 6.52 seconds. The top two finishers in each event make the American world championships team if they have met qualifying standards. Carmelita Jeter dominated the women's 60m, running 7.02 seconds, the second fastest time in the world this season. Two-time world indoor hurdles champion Terrence Trammell, outdoor women's long jump world gold medalist Brittney Reese and the surprising Debbie Dunn also set world seasonal bests at the trials, which doubled as the US championships. Trammell cruised to victory in 7.41 seconds in the 60m hurdles, while Olympic bronze medalist David Oliver was second in 7.54 seconds. Dunn unexpectedly won the women's 400m in a meet record 50.86 seconds, another world best for 2010. Hurdler Bershawn Jackson won the men's 400m title in 45.41 seconds, while Reese leapt 6.89m to win the long jump. Defending world indoor gold medalist Lolo Jones was edged by Ginnie Powell in the women's 60m hurdles, but still made the team. Powell clocked 7.87 seconds with Jones second in 7.89. Christian Cantwell tuned up for a world title defense in the men's shot put with a winning heave of 21.13m.
