Ireland's Derval O'Rourke lowered her national record to 12.67 seconds as she finished a magnificent fourth in tonight's 100 metres hurdles final at the World Championships in Berlin.

JUSTIN GATLIN became only the second man in World Championship history to complete the 100m/200m sprint double in Helsinki last night when he outgunned the young pretenders to add the 200m title to the 100m crown he won on Sunday.
