The Polish world No. 1, who triumphed in Paris in 2020, notched up her 29th straight match victory.
Świątek will next face the winner of a match pitting American Alison Riske against Ukrainian Dayana Yastremska in 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 world number one in women's tennis, becoming the first Pole to top the WTA rankings.
