It was an emotional 21-year-old who took home the victory at the American competitions, as well as the national championships, in Oregon and secured an Olympic ticket.
She ran straight up to the stands where she was hugged by several family members.
At the press conference afterwards, Richardson said that her biological mother, who abandoned her when she was little, passed away last week.
- This year has been crazy for me.
In fact, no one knows what I've been through.
Everyone has problems and I understand that, but you see me on the court with this "poker facet" I put on.
No one but my family and my coach know what I am going through on a daily basis, she says.
Tried to take his life in high school
Richardson, who previously told about her tough upbringing in Dallas and that she tried to take her life when she went to high school, thanks her family for allowing her to compete in her first Olympics.
- My family is everything to me.
Hugging my grandmother was more important than winning the race.
Without my grandmother, there would be no Sha'Carri Richardson, she says.
Richardson is the second fastest woman in the world this year in the 100 meters after running in April at 10.72. Only the two-time Olympic gold medalist Shelly-Ann Fraser-Pryce ran faster with 10.63.
On Saturday, the 21-year-old showed that she will give the Jamaican a real match in Tokyo next month.
