East St. Louis High School graduate Dawn Harper won her preliminary heat to advance into the semifinals of the women's 100-meter hurdles on Friday at the U.S. Track and Field Championships in Des Moines, Iowa.
Harper finished in 12.60 seconds to win her heat. That time ranked fourth-best out of the 16 runners who will advance to Saturday's semifinals.
NCAA champion Brianna Robbins ran the top time with a 12.33. Queen Harrison ranked second with a 12.44 and Lolo Jones was next at 12.50.
All but Jones' time were run in a wind stronger than 2 miles per hour, making them considered wind-aided.
Robbins owns the top time in the world for 2013 with a 12.39. A 12.60 run by Harper earlier this year in Doha, Qatar, ranked second before being bested by Jones on Friday.
Semifinals in the 100 hurdles are scheduled for 2:25 p.m. Saturday. The top four finishers in each of the two races advance to the final, scheduled for 5:52 p.m. Saturday.
Harper was the gold medalist in the 100 hurdles at the 2008 Beijing Olympics and took silver four years later at the London Games.
