MELBOURNE, Australia (AP) — Top-ranked Iga Swiatek will face 2020 champion Sofia Kenin in the first round and potentially 2016 winner Angelique Kerber or Danielle Collins in the second in a tough start to her bid for a first Australian Open title. Defending champion Novak Djokovic’s bid for a record-extending 11th Australian Open title will start against a player who was in the qualifying rounds and could include a third round against Andy Murray and a quarterfinal against last year's runner-up Stefanos Tsitsipas. The draws to determine singles brackets were held Thursday, with the return of former champions Naomi Osaka, Kerber and Caroline Wozniacki to Melbourne Park after maternity breaks resulting in some high-pressure opening rounds.
