Serena's not happy with Sharapova's book

Serena's not happy with Sharapova's book

Maria Sharapova set up a mouth-watering French Open fourth-round encounter with Serena Williams after the pair eased through their third-round matches on Saturday.

Williams and Sharapova meet in the fourth round Monday at Roland Garros.

Next up for Williams as she competes in a major tournament for the first time in 16 months - and since giving birth in September - will be a familiar foe: Maria Sharapova.

Third-seeded Garbine Muguruza of Spain has crushed Samantha Stosur 6-0, 6-2 to advance to the fourth round of the French Open.

"I think what happens there should definitely stay there and not necessarily (be) talked about in a not-so-positive way in a book".

However, Williams found the breakthrough once more and soon set up a tie with Sharapova.

Heading into Wimbledon in 2013, they took swipes at each other's personal lives.

Nadal, who lost only two points in the first five games, will next play Germany's world number 70 Maximilian Marterer, who beat Estonian lucky loser Jurgen Zopp.

Two-time Grand Slam champion Petra Kvitova saw her dreams of victory in Paris ended by a fantastic display by Anett Kontaveit.

Williams played her finest set of her comeback in the opener, hitting 10 winners and just three unforced errors as she moved into a 6-3 lead after just 31 minutes. Banishment followed. For a year since she has been rebuilding her career, now ranked 30 in the world. "I just started. So I'm just really trying to get my bearings and trying to feel out where I am and see where I can go", said the 36-year-old Williams.

"It was Serena whom I beat in the Wimbledon final to emerge on the worldwide stage at seventeen, and it's Serena who's given me the hardest time since", Sharapova wrote.

"If I didn't play my best tennis, I realised that it would be very hard", she said.

Williams was asked about Sharapovas book, which was published past year.

Czech Pliskova made the semi-finals here a year ago, and may fancy her chances against Sharapova, who had to fight hard to get past Richel Hogenkamp and Vekic in her first two matches. Before her incident of drugs or not, she was doing good, she's doing well again.

"I think the name Williams carries a lot of weight at Grand Slams", Goerges told SID, an AFP subsidiary.

"It's not a surprise to me, actually". No sooner had Sharapova packed her bags than she failed a test for the banned substance meldonium - which she announced at a stage-managed press conference in a dowdy Los Angeles hotel in March, pre-empting the official statement by the International Tennis Federation.

There were plenty of other results involving top names at the French Open on Saturday.

Other women moving into the fourth round included 2016 champion Garbine Muguruza, two-time French Open finalist Simona Halep, two-time major-title victor Angelique Kerber and reigning US Open champion Sloane Stephens.

In the men's event, Rafael Nadal swept into the round of 16 with a 6-3, 6-2, 6-2 victory over France's Richard Gasquet.

Even if Williams vs. Sharapova has not been competitive, it's still compelling.

This is Williams' first Grand Slam tournament since January 2017, when she won the Australian Open while pregnant.
