The Polish world No. 1, who triumphed in Paris in 2020, extended her winning streak to 32 matches.
Świątek will next face Jessica Pegula of the United States for a place in the last four of the women’s singles competition in the French capital.
The Polish player earlier this month won the Italian Open clay-court tournament in Rome, defending her crown and claiming her eighth career singles title.
The 20-year-old, coached by countryman Tomasz Wiktorowski, in early April took over as the new number one in women's tennis, becoming the first Pole to top the world rankings.
