Serena Williams will face Zarina Diyas in comeback match at Indian wells

She gave birth to her daughter, Alexis Olympia Ohanian Jr., on Sept. 1, and then spent six weeks in bed because of serious complications from childbirth. She did not resume practicing until December.

Williams officially returned to professional tennis on Feb. 11 by playing a Fed Cup doubles match with her sister Venus against the Netherlands. They were beaten, 6-2, 6-3, by Lesley Kerkhove and Demi Schuurs after the United States had clinched the victory in the first-round matchup.

Williams looked rusty at that event, as she did in an exhibition against Jelena Ostapenko in late December. Williams also played in the Tie Break Tens exhibition at Madison Square Garden on Monday night.

After more than a year away from the tour, Williams has no official ranking. If she defeats the 53rd-ranked Diyas, she would face No. 29 seed Kiki Bertens in the second round, with her sister Venus a possible third-round opponent.

In an interview with WTATennis.com, Williams’ coach, Patrick Mouratoglou, said: “The plan is to get back to her best level. She has been practicing hard for that, and competition is part of the process. She needs more than anything to compete and that is why she will plan to play Indian Wells and Miami.

“We do not know how much time she will need to get her best level back, and I think that we should give her the necessary time for that without having too much expectations at the start.”

He added that her target was to win Grand Slam titles and that he expected Williams to be back to her best by the French Open in May.

The Indian Wells tournament also marks the return of Victoria Azarenka. She has not played a tour event since Wimbledon in July. She has decided not to play outside California, where she lives, until a custody dispute over her son, Leo, is resolved. Azarenka, now ranked 204th, will face Heather Watson in the first round, and with a win, would play 13th-seeded Sloane Stephens in the second round.

The men’s single draw at Indian Wells has been decimated by injuries. Second-ranked Rafael Nadal will not play because of a right hip injury he suffered at the Australian Open in January. Stan Wawrinka, still bothered by a knee injury, will also skip Indian Wells, as will seventh-ranked David Goffin (eye). Andy Murray remains sidelined after hip surgery, but Novak Djokovic, who has been bothered by a right elbow injury for months, is on the entry list for Indian Wells. He has been training in nearby Las Vegas with his coach Andre Agassi.

The BNP Paribas Open will be Roger Federer’s first tournament since returning to the No. 1 ranking. He is the defending champion.
