Prior to the competition, Australian Sally Pearson led the season's rankings with a time of 12.48 seconds and was undefeated on the Diamond League circuit. The United States team provided the next fastest athletes that year in the form of Kellie Wells, Danielle Carruthers and the 2008 Olympic champion Dawn Harper. The defending champion Brigitte Foster-Hylton of Jamaica was in poor form, while the other 2009 medalists (Priscilla Lopes-Schliep and Delloreen Ennis-London) were absent. Tiffany Porter, Lisa Urech and Perdita Felicien were the only other top-ten-ranked athletes to compete.

Sally Pearson was the story here, winning her semi final in 12.36, equal to the number 5 performer in history. The time improved on her own Oceanian area record and Australian national record. Kellie Wells looked strong by opening up a large lead in her semi final, but clipped the ninth hurdle and struggled to maintain her balance as she finished in second.

In the final, it was Pearson in the lead from the gun. Running smoothly, she was not challenged, running 12.28, to make her the number 4 performer in history. Nobody had run as fast in nearly two decades. The time is a new Championship record and again improved her Oceanian area record and Australian national record. Behind her, Danielle Carruthers outleaned Dawn Harper for the silver medal, both athletes finishing in the same time. Wells hit the seventh hurdle and crashed to the ground, not finishing, joining the tradition (Gail Devers, Lolo Jones) of American favorites crashing on hurdles in major championships.
