Canada’s Leylah Annie Fernandez rallied for a 1-6, 6-2, 6-3 victory over No. 31 seed Magda Linette of Poland in her main-draw debut at the French Open on Monday.
The 18-year-old from Laval, Que., won the girls' tournament at the clay-court Grand Slam last year before rising to the women’s ranks.
It marks the second straight Grand Slam in which Fernandez has won her opening-round match. The world No. 100 lost to top American Sofia Kenin in the second round of the U.S. Open.
Fernandez will face world No. 47 Polona Hercog of Slovenia in the second round of the French Open.
Both of Canada’s entrants in the women’s singles draw have reached the second round.
Eugenie Bouchard of Westmount, Que., who received a wild card into the event, beat Anna Kalinskaya of Russia on Sunday and will face Australia’s Daria Gavrilova in the second round.
Meanwhile, Montreal’s Félix Auger-Aliassime and Toronto’s Steven Diez both are out of the men’s competition after suffering first-round losses on Monday.
Auger-Aliassime, the No. 19 seed, lost 7-5, 6-3, 6-3 to world No. 52 Yoshihito Nishioka of Japan.
Diez, a qualifier, lost 4-6, 6-3, 6-3, 6-4 against American Mackenzie McDonald in his main-draw debut at a Grand Slam.
The loss for Auger-Aliassime continued a disappointing clay-court season for the 20-year-old Canadian. Since transitioning to the clay after a run to the fourth-round at the U.S. Open, Auger-Aliassime has won just one of four matches.
Auger-Aliassime had 58 unforced errors, 24 more than Nishioka.
Nishioka is now 2-0 lifetime against Auger-Aliassime. The Canadian lost a third-set tiebreaker to Nishioka in Indian Wells, Calif., last year.
“Today was tough for me over all, what he was bringing in the match,” Auger-Aliassime said after his French Open debut. "I knew him, knew it was going to be tough to go through him, [he was] going to put a lot of balls back. Obviously the conditions were not the best for me. ... He played good.
“Also, you know, I wasn’t good, and I could have been better on many of those opportunities. So, you know, I give him credit and I take responsibility on that because I just felt like there is too many times where I just didn’t step up and play a decent point.”
Auger-Aliassime added the result was “difficult to accept.”
No. 9 seed Denis Shapovalov of Richmond Hill, Ont., and Vancouver’s Vasek Pospisil are scheduled to play their first-round matches on Tuesday.
