Caroline Wozniacki races into fourth round at French Open

Earlier, Halep refused to blame a rain delay for her sluggish start as she recovered to reach the second round of the French Open.

Elina Svitolina had not considered herself one of the favourites for the French Open title prior to her third-round exit, but Caroline Wozniacki looks like a serious contender. The Williams sisters last won a women's doubles slam in 2016 at Wimbledon.

World number one Halep put her slow start down to nerves.

The 30-year-old hit 20 more winners than Svitolina but is not developing an ego despite a rapid rise from obscurity, interacting with a tweet from a media outlet in which her name was spelled "Buzarnesco" by light-heartedly posting: "They can't spell my name yet, but I'm in the second week of @rolandgarros!" "I didn't feel the pressure, because I know that every match is tough at this tournament, so I don't expect anything".

"But what I expect from myself is to go there and to play as I play in practice".

"The result, it's going to come if I play well. If not, I just have to fight and to try to not give up even one point".

She only has two quarter-final appearances to show for her 10 previous Roland Garros appearances, but three-times victor Wilander sees something different in her this time after she won her maiden grand slam at this year's Australian Open.

The Us Open champion holds a 16-2 record in Grand Slam second-round matches, including a 5-0 record in Paris, and clinched the third-round losing just six games overall.

She dropped serve five times and made 29 unforced errors, bowing out on the first match point when she buried another forehand into the net.

'It was definitely a good match.

"We don't often talk about her at the French Open but Caroline Wozniacki has now won a slam and that tends to help you a lot when you are playing on the surface on which you've had the least success", Wilander, Eurosport's lead tennis expert and presenter of the daily Game, Schett and Mats, told Reuters. "I don't think I have any secret". It's been already from the off-season.

"I think it makes a huge difference".

"I wasn't injured, so I really could go for it".

"Maybe she doesn't have the power to hit through the court if it's damp and heavy but I think being a Grand Slam victor she will be looser on impact, more carefree". "Yeah, so far I'm really glad with that".

Serena Williams continues her bid for a 24th grand slam title against German 11th seed Julia Goerges on Saturday.

The American siblings had to come from behind Japanese duo Shuko Aoyama and Miyu Kato.
