Fifth seed Elina Svitolina defeated Poland's Magda Linette in a rain-delayed match to reach the fourth round at Roland Garros in Paris on Sunday.
Ukrainian Svitolina needed one hour and 29 minutes to defeat Linette 6-4, 7-5 in an error-ridden clash on Court Suzanne Lenglen.
Though the 22-year-old never dropped her serve in the match she was far from her best serving five double faults along with 25 unforced errors but was still able to overpower her opponent.
Svitolina is being touted as one of the favourites to win the clay court slam having come into the Roland Garros event winning the Rome and Istanbul claycourt tournaments.
In the first set, the solitary break of serve happened in the third game for the fifth seed to go on and claim the set 6-4.
The second set was similar to the first with Svitolina playing the big points well despite making errors at times.
The important solitary service break happened in the 11th game and then the fifth seed served out the match winning it 7-5.
Svitolina's next opponent is Croatian qualifier Petra Martic, who beat Latvian 17th seed Anastasija Sevastova 6-1 6-1.
After her victory, Svitolina said she was very happy to have won the match.
"Roland Garros has always been special for me," Svitolina said courtside.
"I'm very happy that I could win three matches here and hopefully I will keep it going. I was trained to stay focused and I'm happy I could finish it early."
