Didn't Nadal have a nasty blister at the 2017 or 18 (I forget which) AO final against Federer? Once that opened up it was all over. Though Nadal will fought as much as he could.
Raducanu looks like she's given up.
Medvedev showing his quality over on Rod Laver. Kyrgios put up a decent fight, but he just can't stay with him. The Russian is a machine. Just gets on with business. No reaction to winning or losing points, nothing phases him. Love it. His serve is just a rocket.
EDIT: She fought back. Good on her. She does seem to let her head drop at times though.
