Coco Gauff made a statement of intent as she steamrollered grand slam debutant Julia Avdeeva in the French Open first round.

The world number three needed just 52 minutes to complete a comprehensive 6-1 6-1 rout on Court Suzanne-Lenglen.

Runner-up to Iga Swiatek two years ago, Gauff has also reached a further two quarter-finals in her four previous appearances at Roland Garros

The reigning US Open champion, who reached the Italian Open semi-finals last time out on clay, wasted little time in launching her quest for another deep run in the French capital.

Avdeeva had come through three qualifying matches to secure her maiden appearance in the main draw of a major.

However, the world number 208 simply had no answer for a relentless Gauff, who did not face a single break point and lost just eight points in her seven service games.

Sealing her biggest victory in a completed match at Roland Garros, the 20-year-old set up a second-round clash with 2021 semi-finalist Tamara Zidansek.

Data Debrief: 50 up for Gauff

An Australian Open semi-finalist in January, Gauff's quickfire victory was also her 50th match win in the main draw of a grand slam, becoming the ninth American woman to reach that milestone before turning 21.

The 20-year-old lost just one point off her own serve, and is now 16-3 in first-round major matches (5-0 at Roland Garros).
