There is a lot of mystery around Serena Williams's First part of 2018 schedule. The 23-time Grand Slam champion is expected to come back to compete in time for Australian Open according to tournament director Craig Tiley and WTA CEO Steve Simon, but she will probably need to play some matches in a preparation tournament, which is still unknown.
Brisbane International, which takes place in the first week of the new year, is expected to have the best field on the men's side with Andy Murray, Rafael Nadal, Nick Kyrgios and Grigor Dimitrov to play, but also on the women's with Garbine Muguruza, Karolina Pliskova and Sloane Stephens. However it is "highly" unlikely to feature Serena, said tournament director Geoff Quinlan after contacting the former World No. 1's management according to Courier Mail.
'The messaging through her agents was, ‘Thanks for reaching out’. But it is highly unlikely we will see Serena in Brisbane this time', Quinlan said. 'It’s not to say she may not enter. If she is inclined, she could still enter later. The start of her season will probably look different to what it has in the past. She has played here (three times) and has also played Hopman Cup and Auckland (in the first week of a season).'
So there may be two options: play Kooyong exhibition, which is unlikely, or Sydney which takes place the week before Australian Open and will feature Serena's sister Venus. In 1 September 2017 Serena gave birth her baby girl Alexis Olympia Jr., she has not been posted any photo or video featuring herself playing tennis yet.
