Keys is the first semifinalist in Melbourne
American Madison Keys is the first semifinalist at the Australian Open.
The 51st American in the world rankings definitely defeated the world number 4 Barbora Kreychikova in the quarterfinals and repeated her achievement from 2015.
In the next phase, she will face the winner of the match between Ashley Barty and Jessica Pegula.
"I want to cry. This moment means a lot to me. Last year was very difficult for me. We started literally from scratch with my team and fortunately everything works out. I am proud of myself and the people around me who helped me overcome this difficult period, "Keys said.
Her success over Krejcikova means that Barty will keep her first place in the world rankings, as theoretically the Czech could have replaced her.
