French Open organizers won’t give Serena Williams a seeding.

PARIS — Serena Williams’ return to Grand Slam tennis from maternity leave just got even tougher.

French Open organizers announced Monday that they will not give Williams a seeding.

“This year again, tournament officials will establish the list and ranking of the women’s seeds based on the WTA ranking,” the French Tennis Federation said in a statement to The Associated Press. “Consequently, [the seeds] will reflect this week’s world ranking.”

Williams, a three-time French Open champion, is expected to play in her first major since giving birth to her daughter in September.

While Williams can enter Roland Garros under the WTA’s protected or “special” ranking rule, it’s up to Grand Slam organizers to give her a seed.

While she was No. 1 when she left the tour to give birth, Williams is currently ranked No. 453.

Without a seeding, the 23-time Grand Slam champion risks facing highly ranked players in the early rounds.

The WTA is considering a rule change to add protected seeding for highly ranked players returning from maternity leave but the earliest that could take effect is next year.

“I would like to see that [rule] change,” Maria Sharapova said at the Italian Open last week.

“It’s such an incredible effort for a woman to come back from physically, emotionally. … There’s just another whole dimension to the travel, to the experiences, to the emotions to the physicality of every single day.

“Tennis is such a selfish sport but I think when there’s a child in your life you lose a little bit of that, because there’s something that’s so much more important,” added Sharapova, who has lost three Grand Slam finals to Williams. “So, yeah, I definitely think that would be a nice change.”

The French Open draw will be made Thursday, with the tournament starting Sunday.
