The 23-time Grand Slam victor also said on Friday she's not sure if she will participate in the remaining Grand Slam events this year, as part of her goal of catching up to 24-time victor Margaret Court.
Williams had initially targeted last month's Australian Open for a comeback, but abandoned that ambitious goal after declaring she was not 'where I personally want to be. US captain Kathy Rinaldi has the right to change her Sunday lineup after Saturday's play. When I'm too anxious, I lose matches, and I feel like a lot of that anxiety disappeared when Olympia was born, Williams said.
Venus Williams swept aside Arantxa Rus in straight sets to take the defending champion United States 1-0 up in their Fed Cup first-round tie against the Netherlands on Saturday (Feb 10).
But this weekend's headline is the return of Serena Serena, who participated in a Dec.30 exhibition match but otherwise hasn't played since that 2017 Australian Open.
Although Serena isn't scheduled to play any singles matches this weekend, that could change.
Seven-time Grand Slam victor Venus Williams needed an hour and 19 minutes to brush aside her 124th-ranked Dutch opponent Arantxa Rus 6-1, 6-4.
"It's definitely the start of a long process", Serena said.
A video posted to Serena's Instagram story shows the new mom clad in Team USA's uniform, smiling and pointing the camera at her family behind her at the Fed Cup in Asheville, North Carolina. Sunday's scheduled singles matches have Venus Williams facing Hogerkamp and Vandeweghe taking on Rus. 'It goes unsaid (that) 25 is obviously something that I would love, but I'd hate to limit myself'.
Williams' daughter, Alexis Olympia Ohanian Jr., was born September 1.
"I'm ready and really excited that I was chosen to be on the team".
A more laboured win followed for the mercurial CoCo Vandeweghe, who lost her first set to Richel Hogenkamp and broke a racket in frustration during the second before fighting back to a 4-6, 7-6 (8/6), 6-3 victory. I would never write her off.
Williams will be bidding to emulate Margaret Court, Evonne Goolagong and Kim Clijsters, who all won Grand Slam titles after having children, when she returns to the circuit.
"It actually is a really flawless opportunity to try to come back", Williams said.
