LONDON -- Two of three U.S. men who competed in the semifinals of the 110-meter hurdles advanced to the final, which will be contested later Wednesday night.
Jason Richardson, who trains in Los Angeles, won his heat in 13.13 seconds. Aries Merritt, of Marietta, Ga., won his heat in 12.94 seconds, .01 off the world-leading time he has recorded three times this season.
But in the third semifinal, Jeff Porter of Somerset, N.J., finished fifth in 13.41 and didn’t qualify.
World record holder Dayron Robles of Cuba had the second-best semifinal time, a season-best 13.10 seconds. Robles set his record more than four years ago.
Richardson had a strong start and cruised to the finish.
Merritt ran all the way through, another impressive performance and his fourth sub-13-second mark this season.
