Osaka needs to get back to playing tennis. Due to her "mental health" stunt she's lost all match practice and seems to be more focused on the off-court marketing stuff. The hard courts' best WTA player of the last couple of years is now losing to opponents she'd blow away in 55 minutes in peak form. If this loss doesn't wake her up I don't know what else will. This season is basically a wash for her anyway.
As for Alcaraz, well, that is a huge result for ATP. They have more or less found the next Nadal who now gets that big elite scalp and will milk him together with Sinner like crazy going forward.
