Williams has already benefited from this rule in the past as in 2011 she was ranked 25th before the start of Wimbledon but seeded seventh for the championships.
At 36, the American is looking to regain her top form following the birth of her daughter last September.
Despite her No. 454 world ranking, Serena Williams says she is still drug tested twice weekly.
"Serena will play the French Open to win it". The owner of 23 major singles titles, a record for the 50-year Open era, Williams hasn't played on one of her sport's most prestigious stages since winning the Australian Open in January 2017, while pregnant.
At Miami, Williams ran into Indian Wells champion Naomi Osaka in her opening match and was easily beaten. It's normal to have protected ranking ... Williams was eventually able to make a recovery, but not before spending her fist six weeks of motherhood confined to a bed in her home.
"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", Sharapova said, adding: "There's just another whole dimension to the travel, to the experiences, to the emotions to the physicality of every single day". That leaves the 23-time Grand Slam singles victor, who was ranked No. 1 in the world at the time she went on maternity leave, in danger of having to square off with a top player in the early rounds - and those players are facing the same unpleasant possibility.
At present, the Women's Tennis Association (WTA) treats pregnancy the same way as an injury or illness, though they're considering a rule change that would treat maternity leave differently.
In Wimbledon, like in all the other tournaments on the women's side, the seeding formula is authomatically given by the player's ranking. But she'll try for her 24th Grand Slam as an unseeded competitor.
"But right now, I'm taking a little bit at a time".
"I think it's more of a protection for women to have a life", Williams said.
"It's normal to give birth to a kid. We remain committed to evolving with the needs of our players and are very supportive of those players returning from maternity leave to the tour".
"It's wrong, they should protect players", Evert, who will be working for broadcaster ESPN during the Paris fortnight, told Reuters by telephone. "The rule is now under further review as part of our 2019 rules process".
