Osaka winning without much trouble is expected, She's clearly the best hard court player in the world right now.
Djokovic schooling Medvedev is a bit of a surprise considering their H2H record and forms, I expect it to be closer. I guess it shows that what Nadal is to French Open, Djokovic is to Australian Open.
Funfact:
-Osaka never lose any grand slam match once she got past the 4th round (12-0 , 4 Slams won)
-Djokovic never lost Australian open match once he gets to the semifinal (18-0, 9 AO titles)
