Swiatek, 20, has a considerable disadvantage with the Australian of 2,204 points.
The Pole was ranked 4th in the world before conquering the WTA 1000 in Indian Wells last week and rising to second place on March 21.
In this way it should be N.1 in the world in the new classification that will be published on Monday.
Swiatek, who has shown great consistency since his win at Roland Garros in 2020, said at the Miami tournament that he tries not to think too much about it all.
“They say that it is possible that I become No. 1 in the world,” he declared.
“When we read all the information, all the rules that can apply, we realized that it doesn’t make any sense to really think about all that at the moment because we have so little time to prepare for another tournament,” added the semi-finalist of the last Open of Australia.
Swiatek currently has 691 points ahead of Greece’s Maria Sakkari in third.
Barty, with three Grand Slam titles to his name (Roland Garros 2019, Wimbledon 2021, Australian Open 2022), had been in first place in the WTA rankings since September 2019.
On Wednesday, he surprised everyone by announcing his retirement at just 25 years old, explaining that he had fulfilled his dreams and lacked “the physical motivation, the emotional desire” to continue.
“In the next classification my name will be removed from the list,” said the Australian at a press conference in Brisbane on Thursday.
As for her future, Barty was evasive when asked by reporters.
“They will have to wait, I am not going to reveal everything here,” he said.
Barty, who is of Aboriginal origin, confirmed that she wants to work more with local Australian people, and spend time with her parents, claiming to be a “homebody”.
The entrance Barty withdraws from the WTA rankings and opens the way to number 1 for Swiatek was first published in diary TODAY.
