Serena Williams remained on course for a record-equalling 24th Grand Slam title after outlasting world No 1 Simona Halep in a fabulous contest to reach the Australian Open quarter-finals.
Williams has looked in ominous form so far at Melbourne Park as she seeks one more Grand Slam title to put her alongside Margaret Court’s record 24 titles.
And the 37-year-old extended her winning record over the Romanian to 9-1 with a bruising 6-1 4-6 6-4 victory on Rod Laver Arena on Monday.
