Top seed Iga Swiatek says it was "disappointing and surprising" to hear French Open tournament director Amelie Mauresmo say women's games were not as appealing as men's matches.
Mauresmo, a former world number one, has faced criticism after only one of the 10 night sessions at this year's event was a women's match.
Poland's Swiatek, 21, has played all of her five matches in the day time.
"I think women's tennis has a lot of advantages," said the world number one.
The only night session to feature a women's match was last Thursday, when France's Alize Cornet beat Latvian 13th seed Jelena Ostapenko in three sets.
