Earlier, Russian teenager Mirra Andreeva beats Cristina Bucsa to advance – despite joking she did not like her early morning wake-up call.
The 18-year-old was first on Court Suzanne Lenglen on Tuesday morning, stepping out at 11:00 local time in Paris.
Playing her first Grand Slam as a top-10 seed, Andreeva recovered from a double break deficit in the first set to win 6-4 6-3.
“Honestly, it was very difficult,” Andreeva said.
“I’m not really happy because I don’t like to wake up early.”
Men’s world number 11 Daniil Medvedev has also complained about early starts and joked he may “boycott” morning matches.
However he did not fare as well as Andreeva, losing his morning match to Britain’s Cameron Norrie in a five-set epic.
Andreeva added: “I had to wake up at 6.40 and then I had 35 mins to pack my bags and do everything.
“Then 25 minutes to have breakfast, 30 minutes to come here and then I spent 11 minutes in the locker room and then we did the warm-up and went on court.
“It is very well planned.”
Andreeva, who reached the semi-finals at Roland Garros last year, will face Suzan Lamens of the Netherlands next.
