Iga Swiatek will replace Ash Barty as the No.1 women’s player in the world after her 6-2, 6-0 thrashing of Viktorija Golubic in the second round of the Miami Open on Friday.

The 20-year-old is the first Polish player to achieve the ranking and the 28th women ever to reach the peak, which will be official when the WTA rankings are updated on April 4. Swiatek, who has already won titles in Doha and Indian Wells this year, takes over after the Australian’s surprising announcement to walk away from the game.

Swiatek said capturing the top ranking was a “surreal” achievement. “It’s a dream come true, for sure,” Swiatek told reporters. “It’s that kind of thing that I wanted to happen someday, but I didn’t really know that it’s going to be possible for me.”

Barty wasted no time in congratulating Swiatek.

“There is no better person,” Barty said in a message after the match.
