Matteo Berrettini

"I think at his age I didn't even have an ATP point."

After four hours and ten minutes, the Italian edged the 18-year-old, 6-2, 7-6 (3), 4-6, 2-6, 7-6 (10-5), to enter the last 16.

Gael Monfils

The Frenchman took a nasty fall in the opening set against No. 16 seed Cristian Garín, but recovered quickly. He captured a 7-6 (4), 6-1, 6-3 win and is through to the last 16.

Madison Keys

She's back! For the first time since 2019, the American is back into AO's round of 16. She took out Wang Qiang 4-6, 6-3, 7-6 (10-2).

Denis Shapovalov

"I've gotten very familiar with the ice bath the last week. We've become very good friends."

The Canadian found himself in another over three-hour tussle, but he took his chances against the always tough Reilly Opelka to advance into his first round of 16 at the major. Cheers to climbing into the ice bath yet again!

Badosa and Kostyuk

The Spaniard and Ukrainian's friendship had everyone in their feels on Day 5. The No. 8 seed held off Kostyuk, 6-2, 5-7, 6-4, to advance into her first Australian Open Round of 16.
