American Sofia Kenin broke a series of losses from four matches on clay and won her opening match at the French Open, defeating the 2017 champion Jelena Ostapenko in three sets.
The game finished 6-4, 4-6, 6-3.
Kenin placed fourth and became Iga Swiatek’s runner-up last year. The victory was Kenin’s first since announcing that he was no longer coaching his father, Alex.
Kenin converted nine of 10 break points against Ostapenko and won, although he lost service seven times.
Earlier, Bianca Andreescu, champion of the US Open in 2019, was outside the French Open in the first round after losing 9-7 third set.
The second participation of the sixth placed Andresque in the main scheme of Roland Garros ended with a 6-7 (1), 7-6 (2), 9-7 defeat against the 85th Tamara Zidanshek from Slovenia.
Andrescu retired before his quarter-final last week in Strasbourg with an abdominal injury.
Zidanese was 0-2 at the French Open.
Defending the French Open champion Iga Suatek continued exactly where he left off last year, winning the title: escaping another opponent in this way and that of the red clay of Roland Garros in a straight victory.
