With the victory, the Japanese tennis star also extended her winning streak at the Grand Slams to 15 matches in a row. Osaka booked her spot in the second round by overcoming Tig in a tight second set ending the game which lasted for one hour 47 minutes.

The 23-year-old, who has won her last two consecutive majors but did not feature in French Open last year, is seeking a fifth Grand Slam title, and first on a surface other than hard court.

Osaka will now lock horns with another Romanian, Ana Bogdan, who knocked out Italian tennis player Elisabetta Cocciaretto 6-1, 6-3.

Earlier this week, Osaka said she would not be taking part in press conferences during the French Open in order to ensure better mental health.
