The Polish top seed dispatched the 303rd-ranked British player 7-6, 6-3 in the quarterfinals of the women's singles on Friday after a grueling two hours and four minutes on court, news outlets reported.
Świątek, who is defending her title at the clay-court tournament in Stuttgart, had a bye in the first round and eliminated Elise Mertens of Belgium in the second round. She will now face Kazakhstan's Elena Rybakina for a place in the championship match.
The Polish player, coached by countryman Tomasz Wiktorowski, last month won the BNP Paribas Open tournament at Indian Wells, California, claiming her 19th career singles title.
In February, Świątek won the Qatar Open in Doha for the third consecutive time.
The 22-year-old Pole in November regained her spot at the top of the world rankings in women's tennis after winning the season-ending WTA Finals tournament in Mexico.
She now leads the WTA rankings with 10,835 points, ahead of Belarusian Aryna Sabalenka, with 8,045 points, and American Coco Gauff, with 7,205.
The 2024 Stuttgart Open runs until Sunday.
