It’s interesting, maybe he’s tired? I was watching AO 2019 highlights and about the 2nd set after almost every point he’s like dragging his feet and it’s starting to bother me lol.
He probably does it more, I noticed it at USO 2019, however has he always done this?
Edit: an example is at 2:58, when he walks to get the towel.
