Elina Svitolina will face Elena Rybakina in a marquee fourth-round tie at the French Open after successfully moving into the second week.

The Ukrainian defeated Ana Bogdan 7-5 6-2 on Saturday to reach the last 16 for the sixth time in her career.

Both players struggled on serve, with 11 breaks in total during the match, but it was Svitolina who ultimately emerged triumphant after a back-and-forth contest and a rain delay, firing 28 winners.

Fifteenth seed Svitolina will now hope to halt the Paris charge of fourth seed Rybakina, who is yet to drop a set at the tournament so far. It will be a tough ask, but Svitolina does lead the head-to-head 2-1.

An all-American clash between Madison Keys and Emma Navarro on Court Suzanne-Lenglen was one of the other standout matches.

Navarro had never before reached the fourth round at a major, while Keys was a former semi-finalist at Roland-Garros.

But it was Navarro who claimed a hard-fought victory, getting the better of two tie-breaks to win 7-6 (7-5) 7-6 (7-3) to book a huge clash against second seed Aryna Sabalenka.

Jasmine Paolini is also through to round four after seeing off former US Open champion Bianca Andreescu 6-1 3-6 6-0.

Mirra Andreeva, meanwhile, is the youngest player to reach the French Open last 16 since Nicole Vaidisova in 2006 after beating Peyton Stearns in straight sets.

The 17-year-old raced to a 6-2 6-1 win in only 67 minutes.

Sabalenka and Rybakina had earlier completed routine victories over Paula Badosa and Elise Mertens respectively.

Aryna Sabalenka recovered from a slow start to eventually advance to the French Open last 16 a commanding 7-5 6-1 victory over best friend Paula Badosa.

The second seed trailed 4-2 and was a break down in the opening set, but went on to win 11 of the next 13 games to seal a fourth-round clash with either Madison Keys or Emma Navarro. 

Sabalenka has dropped just seven games in her opening two matches at Roland-Garros.

Although, it looked like she may lose the opening set when a fortuitous net shot gave Badosa a second break and a 4-2 lead on Court Philippe-Chatrier.

However, she dug deep from 5-3 adrift, winning the last four games to draw first blood.

The reigning Australian Open champion broke her opponent a further two times on the way to a commanding 4-0 advantage in the second.

Badosa did well to save three match points from 0-40 in game six, but the Spaniard could not rescue a fourth as her opponent continued her surge into the second week.

Data Debrief: Sabalenka completes top four in last 16

Following on from her victories when they met in Miami and Stuttgart earlier this season, Sabalenka became the first player to beat Badosa three times at WTA events in a calendar year.

Joining Iga Swiatek, Coco Gauff and Elena Rybakina, this marks the first time since 2013 that the top four seeds are through to the last 16 in the women's singles at Roland-Garros.

Katie Boulter will play in her first WTA-500 final after she beat American Emma Navarro in straight sets at the San Diego Open.

It took just over an hour for Boulter who won the first set 6-3 and dominated the second 6-1 against the third seed.

The 27-year-old from Leicester dominated on her serve, winning more than 87 per cent of first serve points and allowed just two break points opportunities against her serve, saving both.

Rain stopped play early in the second set, but the delay did nothing to stop Boulter’s momentum as she produced an almost perfect set to secure victory.

Boulter will climb to her career-high WTA ranking after the win as she looks to win her first WTA-500 title in what will be the biggest game of her career so far.
