Melbourne: Top seed Simona Halep saved three match points as she won a marathon third round encounter 4-6, 6-4, 15-13 against Lauren Davis on Saturday.
American Davis lost a toenail in a third set lasting more than two hours and Halep served for the match four times before finally getting across the line on her very first match point.
"I never played a third set so long. I'm almost dead," said the Romanian.
Halep nows plays either 18th seed Ashleigh Barty of Australia or Japan's Naomi Osaka in the last 16 after almost four hours of incredible action -- the longest match of the women's tournament so far.
