At the 2006 Commonwealth Games in Melbourne, Pearson tripped over a hurdle and fell to the ground during the 100 m hurdles final, costing her the chance of a medal. In 2007, she continued to pursue both the 100 m and the 100 m hurdles, making the semi-final of each event at the World Championships in Osaka, Japan. However, in the lead up to the 2008 Olympic Games, she shifted her focus solely to the 100 m hurdles. This decision paid off, with Pearson claiming the silver medal in a dramatic final, where the favourite Lolo Jones stumbled and a photo finish was required to decide the minor medals. After the announcement of the official results a jubilant Pearson celebrated enthusiastically with bronze medal winner Priscilla Lopes-Schliep, and gave an emotional trackside interview.
