Alize Cornet survived stifling heat to outlast former world number one Simona Halep 6-4 3-6 6-4 in a battle of attrition at the Australian Open on Monday, advancing to her first Grand Slam quarter-final where she will meet Danielle Collins.
Collins earlier became the third American woman after Madison Keys and Jessica Pegula to reach the quarters of this year's event after she overhauled Elise Mertens 4-6 6-4 6-4.
