BBC Sport - World Relays: Allyson Felix falls as USA women throw away gold

Felix falls as USA have baton disaster

USA's women throw away an almost certain victory in the 4x200m race at the World Relay Championships in Nassau.

The pre-event favourites looked to be on course to successfully defend their title, but disaster struck on the final changeover between Jeneba Tarmoh and Allyson Felix.

Nigeria went on to claim gold ahead of the hosts Bahamas, who were later disqualified for a late baton changeover, promoting Jamaica and Germany to silver and bronze respectively.
