PARIS — Former champion Maria Sharapova reached the fourth round of the French Open with a dominant 6-2, 6-1 win against Karolina Pliskova on Saturday.
The 31-year-old Russian, seeded 28th after missing this tournament the last two years, needed 59 minutes to win on Court Philippe Chatrier. She broke serve five times against the sixth-seeded Czech.
Sharapova, who has won two of her five majors at Roland Garros, will next face Serena Williams in what will be their 22nd career meeting.
Third-seeded Garbine Muguruza, the 2016 French Open champion, also impressed on the main court. She needed just over one hour to beat Samantha Stosur of Australia 6-0, 6-2.
Sloane Stephens also advanced to the fourth round, but the 10th-seeded American had a much more difficult time beating Italy’s Camila Giorgi 4-6, 6-1, 8-6. Stephens next faces Anett Kontaveit of Estonia, who won 7-6 (8), 7-6 (4) against No. 8-seeded Petra Kvitova.
There was another upset as unseeded Ukrainian Lesia Tsurenko defeated 19th-seeded Slovak Magdalena Rybarikova 6-2, 6-4.
Top-seeded Simona Halep later faced Andrea Petkovic of Germany on the new Court 18.
In men’s third-round action, unseeded Russian Karen Khachanov completed a 6-3, 5-7, 6-3 win against 15th-seeded Lucas Pouille of France. Their match was suspended for rain late Friday.
Fabio Fognini beat Kyle Edmund 6-3, 4-6, 3-6, 6-4, 6-4, while Maximilian Marterer won 6-2, 6-1, 6-4 against Jurgen Zopp.
Rafael Nadal was up later on Chatrier, targeting a 16th consecutive win against Richard Gasquet. The top-ranked Spaniard is trying to win a record-extending 11th title at Roland Garros.
