She saved five break points in the seventh game of the third set. Pliskova finally broke and then held to love for a 5-3 lead on Court Philippe Chatrier.
Pliskova clinched victory with an ace on her first match point.
The former top-ranked player reached the semifinals at Roland Garros in 2017 and next faces Jelena Ostapenko. The big-hitting Latvian player won the French Open that year.
