Sally Pearson equalled her own world leading time of 12.49 seconds in a dominant display over the 100m hurdles at the Diamond League meet in Olso on Thursday.

The world champion overcame a false start by British heptathlete Jessica Ennis to power home 0.07sec ahead of American Kristi Castlin, with US-born Briton Tiffany Porter taking third (12.70).
