PARIS, France - At the start of Roland Garros, four players had a chance to overtake No.1 Naomi Osaka atop the WTA rankings after the French Open: No.2 Karolina Pliskova, No.4 Kiki Bertens, No.5 Angelique Kerber, and No.6 Petra Kvitova. To do so, each will have to do something they have never done: make the French Open final. 

INSIDER DRAW ANALYSIS: Osaka and Serena bid for history, Halep puts on defense

Osaka took over the No.1 ranking after winning her second consecutive major title in January at the Australian Open, ending Simona Halep's 48-week reign at the top of the game. Though ranked No.3, Halep is the defending champion in Paris and therefore cannot add to her point total over the fortnight. 

Here are the No.1 scenarios in Paris:

No.1 Naomi Osaka

Osaka can clinch the No.1 ranking by making the final. Osaka is bidding to become the first woman to win three consecutive majors since Serena Williams in 2015. 

Through the French Open, Osaka will have held the top spot for 19 weeks. The 21-year-old enjoyed a solid clay season so far, making the semifinals in Stuttgart and back-to-back quarterfinals in Madrid and Rome. She has yet to make it past the third round in Paris. 

No.2 Karolina Pliskova

Pliskova needs to reach the final to have a chance at No.1. If Osaka reaches the semifinals, Pliskova would need to win the title. 

Pliskova is a former No.1, having held the top spot for eight weeks in 2017. The Czech comes into Paris having won her biggest title on clay last week in Rome. Her best Roland Garros result came in 2017 when she made the semifinals.  

No.4 Kiki Bertens

Bertens needs to reach the final to have a chance at No.1. If Osaka reaches the Round of 16, then Bertens would need to win the title. 

Sitting at No.2 on the WTA Insider Clay Court Power Rankings behind only Halep, Bertens won the biggest title of her career two weeks ago at the Madrid Open, sandwiching that title run between semifinals in Stuttgart and Rome. Bertens' best result in Paris came in 2016 when she made her first Slam semifinal. 
No.6 Petra Kvitova

Kvitova was forced to withdraw from Roland Garros with a left forearm injury. The Czech announced the news on Day 2 before her opening match.

Kvitova needed to win the title with Osaka not advancing to the semifinals. Kvitova, a champion in Stuttgart, has yet to reach No.1 in her career. Her best result in Paris came in 2012 when she made the semifinals.

No.5 Angelique Kerber

The reigning Wimbledon champion bowed out on Day 1 to 18-year-old Russian Anastasia Potapova. She needed to win the title to have a chance at No.1. 

The German was forced to withdraw from Madrid and Rome due to an ankle injury sustained in practice. Kerber's best result in Paris came with quarterfinals run in 2018 and 2012, and a title run here would complete her Career Grand Slam. The reigning Wimbledon champion, she last held the No.1 ranking in July 2017.
