Serena Williams has praised the introduction of more ranking protection for new mothers on the WTA Tour.
Players coming back from childbirth or injury can use their previous ranking to enter 12 tournaments over a three-year period.
In addition, they will not face a seeded player in an opening round.
"I think it's great," said Williams who gave birth to daughter Alexis Olympia in September 2017 and returned to action in February 2018.
"Women that are younger can go out there and have kids and not have to worry about it, and not have to wait until the twilight of their years to have children, and I think it's a really great rule.
