Serena Williams will make her return to the Australian Open for the first time since winning in 2017 when eight-weeks pregnant, it was confirmed on Wednesday, with virtually all the world's top 100 players due at Melbourne Park.
That includes injury-prone Rafael Nadal and Andy Murray.
Serena returned from giving birth to her first child to reach the 2018 Wimbledon and US Open finals, but suffered upset losses in both to leave her stuck on 23 major wins.
Australian Open organisers said she was among the entries for the opening Grand Slam of the year as she attempts to equal Margaret Court's record of 24.
Her appearance will mark her first major since her controversial rant at an umpire during the US Open final loss to Naomi Osaka, which overshadowed the Japanese star's biggest ever win.
