For most part of the race, Amusan was behind reigning world
champion Williams and America’s Nia Ali but surged ahead in the closing stages,
beating the previous world-leading time of 12.42s set by Tonea Marshall of the
USA on April 20.
Williams finished second in 12.46s seconds, with Christina
Clemens of the USA taking third place in 12.54s.
Another Jamaican athlete, Yanique Thompson, secured fourth
in 12.59s while Ali slipped to fifth with a time of 12.65s.
Amusan and other prominent athletes snubbed the Doha Diamond
League to attend the Jamaica Invitational.
The Nigerian ended last season on a high by winning the
Diamond League in Eugene, Oregon for a third consecutive time, silencing
critics about her disappointing performance at the World Athletics
Championships in Budapest where she placed fifth and lost the title to
Williams.
