Spain's Garbiñe Muguruza, world No. 3, on Saturday qualified for the French Open round of 16 for the fifth straight year, beating veteran Australian player Samantha Stosur 6-0, 6-2.
The 2016 French open champion needed just 62 minutes to earn her third career win in a row against Stosur out of four matches.
The unseeded Australian, world No. 90, was the French Open finalist in 2010, a three-time semi-finalist and the winner of the US Open in 2011.
Muguruza, who won the French Open in 2016, is set to play the next round against Lesia Tsurenko of Ukraine, who beat Slovakia's Magdalena Rybarikova 6-2, 6-4.
Maria Sharapova easily handled the big serve of No. 6-seeded Karolina Pliskova and overwhelmed her 6-2, 6-1 to move closer to a possible French Open showdown against Serena Williams.
Sharapova has won two of her five Grand Slam titles at Roland Garros and is now into the fourth round for the 12th time in 14 appearances at the clay-court major.
The 31-year-old Russian, who is seeded 28th after missing the French Open the last two years, will next play the winner of the third-rounder between 23-time major champion Williams and 11th-seeded Julia Goerges. Williams has won 19 of 21 head-to-head matchups against Sharapova, including the last 18 in a row.
Against Pliskova, Sharapova held an 18-5 edge in winners and broke the 2016 U.S. Open runner-up in five of her seven service games. Pliskova has led the WTA in aces the past three seasons — and is No. 2 in that category this year — but managed only one Saturday.
The match lasted just 59 minutes.
