2004. She made her main-draw debut at Roland Garros in 1989 — before more than half of this year’s women’s field was even born.
No. 27 Svetlana Kuznetsova, the 2009 French Open champion, also advanced, along with No. 26 Sorana Cirstea of Romania.
In the men’s tournament, 11th-seeded Grigor Dimitrov lost to Ivo Karlovic of Croatia 6-4, 7-5, 7-6 (4).
Dimitrov reached the quarterfinals at the Australian Open, but his best result at Roland Garros was getting to the third round in 2013.
No. 5 David Ferrer advanced to the second round, as did No. 32 Andreas Seppi of Italy.
Later Tuesday, seventh-seeded Andy Murray, the 2013 Wimbledon champion, was scheduled to play Andrey Golubev of Kazakhstan.
