Aryna Sabalenka reached the fourth round of Wimbledon for the first time after a comfortable 6-0 6-3 win over Colombian Maria Camila Osorio Serrano.
She will face Elena Rybakina next after the Kazakh's 6-1 6-4 win over American Shelby Rogers.
Seventh seed Iga Swiatek dropped just one game as she raced through with a swift victory over Irina-Camelia Begu.
The Pole, who won the French Open in 2020, beat the Romanian 6-1 6-0.
The 55-minute match could have been even quicker, had it not been for a 10-minute fifth game in the second set.
Swiatek will face Tunisia's Ons Jabeur or 2017 Wimbledon champion Garbine Muguruza for a place in the quarter-finals.
