Serena Williams will lead the charge of American women in the last-eight of the Australian Open and continue her bid for a record-equalling 24th Grand Slam title when she meets a familiar foe in second seed Simona Halep on Tuesday.
Williams, 39, is among three Americans who have made it to the quarter-finals at Melbourne Park this year and Wednesday’s clash between Jennifer Brady and Jessica Pegula has ensured that at least one from the country will be in the last four.
