Naomi Osaka’s bid for a third consecutive Grand Slam title finally gets started on Day 3 of the French Open.
The No. 1-seeded Osaka never has been past the third round in three previous appearances at Roland Garros.
She carries a 14-match winning streak at majors into Tuesday.
The Japanese star plays 90th-ranked Anna Karolina Schmiedlova in the second match on the Court Philippe Chatrier.
Osaka won the U.S. Open last September and then the Australian Open in January.
Also in first-round action are 2009 U.S. Open champion Juan Martin Del Potro and No. 5 seed Alexander Zverev.
A quarterfinalist last year in Paris, Zverev plays John Millman in the first match on Chatrier.
Del Potro plays Nicolas Jarry on Court Suzanne Lenglen.
