Elina Svitolina and Maria Sakkari both survived mini-scares to reach the second round at Roland Garros.
Elina Svitolina managed to defeat world number 1111 Oceane Babel 6-2 7-5 while Maria Sakkari beat world number 129 Katarina Zavatska 6-4 6-1.
Starting with Svitolina, who enters Roland Garros with inconsistent clay court from having lost in the opening round in Madrid but reached the last eight in Rome losing to Iga Swiatek.
The Ukrainian had a nice opening round to settle into her Roland Garros campaign as she began her campaign against French wildcard Oceane Babel.
Svitolina showed her class in the opening set as she broke twice in the first and fifth games to seal the opening set in 30 minutes.
However the second set was much more complicated as some unnecessary unforced errors and passive play saw Babel get the early break in the second set.
Then Svitolina failed to take any of her 10 break points as she fell to a 5-2 deficit.
But the world number six bounced back reeling off five games in a row to take the match and advance into the second round.
Next for Svitolina will be Ann Li, who thrashed Margarita Gasparyan 6-0 6-1.
As for Maria Sakkari she entered the second grand slam having suffered a disappointing defeat in Rome to Coco Gauff.
Once again today, Sakkari showed similar signs of that form as she lost her opening two service games but also managed to break twice of her own.
Her opponent Katarina Zavatska caused the Greek player some problems as she took the match to Sakkari, playing aggressive tennis and playing well on the big points.
It was a case of Sakkari grinding out games when not playing at her best and that is exactly what she did as a break in the 10th game edged out the first set which consequently lead to a massive roar from the 17th seed.
The second set was much more dominating as she broke twice in a 6-1 set to advance to the second round.
Next for Sakkari will be Italian Jasmine Paolini who defeated Stefanie Voegele 7-5 6-1.
In other key results Jennifer Brady, who is under new coach Brad Stine, defeated Anastasija Sevastova 6-3 6-3.
She will face Fiona Ferro next who beat En Shuo Liang 6-1 1-6 6-4 in 1 hour and 42 minutes.
