The 25-year-old set a meet record of 12.29secs to win the women’s 100m hurdles in Zurich and won $30,000 on Thursday.
Newsonline report that Amusan finished ahead of Tia Jones (12.40secs) who placed second and Brittany Anderson in third with a time of 12.42secs.
Her victory shattered Gail Devers’ 22-year-old 12.33secs meet record set in 2000.
Her time was the second fastest legal time ever over the hurdles after the 12.12secs world record she posted in July at the World Championships in Oregon, USA.
In a video posted on Twitter by the World Athletics, Amusan said, “Everyone has doubted me. I just had to prove myself, that I have got it. I am just so thankful for all of this season. I am full of emotions. Now, vacation, rest, and then back to practice.
“I was scared to the teeth getting on that line, but you know, I just had to keep my calm… then yes, its show time! I’m just thankful to have come out here and get the win.”

Amusan said that there was no pressure, that she just felt the need to prove to herself that breaking the World record in Oregon wasn’t a fluke.
“There is no pressure; it was more of proving to myself that I broke the World record and I can do it over and over, it’s not just a one-time thing.
“Even though after the World Championships, it took a toll on me to get back into my rhythm, but with enough rest, I was able to bounce back, and I’m thankful.”
Amusan’s feat in Lusanne has seen her successfully defended four titles this year.
She started the year by retaining her African Championships title in Mauritius back in June, before traveling to Paris to smash her 12.42secs African record with a time of 12.41secs at the Diamond League meeting in Paris.
Then she ran 12.41secs at the Diamond League meeting in Paris, before storming Benin City, Edo State to erase the 12.63secs Nigerian Championships record set in 1997 by Angela Atede in Lagos.
The reigning African champion ran 12.58secs to add the championships record to her collections, before going to the biggest stage in world athletics to achieve legendary status.
The Utep graduate also produced one of the biggest surprises of the World Championships when she sped to a world record of 12.12secs in the semi-finals of the 100m hurdles, following it with a wind-assisted 12.06secs in the final to win gold.
The Nigerian went on to win the Commonwealth Games title with a Games record 12.30secs and in the process became the first Nigerian track and field athlete to successfully defend an individual title at the Games.
