It's gold for Australia's Sally Pearson for the second time in London as she repeats her Olympic victory of 2012 in the 100-meter hurdles. Kendra Harrison, who set a world record here last year, finishes in fourth, while fellow American Dawn Harper Nelson runs a season's best to take silver. "Far out, that was bloody hard," says Pearson after repeating her 2011 World Championships success. "That was just incredible."
