Hazel Irvine introduces live action from day three of the World Championships. There are six titles up for grabs in Berlin, including the battle to be crowned the world's fastest woman. Jamaican Shelly-Ann Fraser is the Olympic champion, though compatriot Kerron Stewart has started the 2009 season in fine form. Another Jamaican, Veronica Campbell-Brown, has been a major winner in the past including the world crown in Osaka in 2007. Kelly-Ann Baptiste of Trinidad has emerged as a genuine star during this campaign, and could be the athlete to prevent a Jamaican clean sweep.
