AO Top 5 Photos, 1/23: Madison Keys is on a mission in Melbourne

The American is back into the Aussie Open's quarterfinal for the first time since 2018. She was virtually unstoppable against Paula Badosa, posting a quick 6-3, 6-1 scoreline to up her winning streak to nine consecutive matches.

Sublime tennis from the 20-time major champ was on display. It took seven set points before the Spaniard captured the opening set against Adrian Mannarino, but from there it was smooth sailing as he grabbed a 7-6 (14), 6-2, 6-2 win.

The world No. 21 is through to the quarterfinals for the second consecutive year in Melbourne. She defeated No. 5 seed Maria Sakkari 7-6 (0), 6-3.

Nick Kyrgios and Thanasi Kokkinakis slipped past No. 15 seeds Gonzalo Escobar and Ariel Behar 6-4, 4-6, 6-4. Next up for the crowd favorites are No. 6 seeds Tim Pütz and Michael Venus.

You have to be able to change things up when facing a two-time Australian champ and the No. 1 Czech did just that. She posted a 6-2, 6-2 score over Victoria Azarenka to reach the last eight.
