PARIS (AP) Serena Williams' return to Grand Slam tennis from maternity leave just got even tougher.
French Open organizers announced on Monday 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."
