Kiki Bertens booked her first win on Monday since the interruption due to the corona crisis.
In the first round of Roland Garros, she battled herself after a difficult start 2-6, 6-2 and 6-0 against Ukrainian debutante Katarina Zavatska.
Bertens had a bad dress last week.
At the WTA tournament in Strasbourg, she had to give up in her first match against Jelena Ostapenko with an Achilles tendon injury.
Partly because of this, she started somewhat insecure against Zavatska, who is only 112th in the world ranking.
"It was very difficult to move", responded Bertens, the global number eight, after she had decided the match in her favor in rainy Paris after more than two hours of play.
"In the first set I barely got my legs working."
"She also started very well and I played too fast", she complimented her opponent.
"It was very difficult to play aggressively and to hit winners. In the second and third set I was more patient and my legs felt much better."
The 28-year-old Bertens will take on Sara Errani in the next round.
The five years older Italian was in the final of Roland Garros in 2012 and won the five previous meetings with the Dutch.
