I think a break can be a very healthy thing if it's approached for the right reason. It's unclear to me what Gavrilova would hope to gain from a break, though.A break wouldn't hurt sometimes, I guess looking at the Barty angle. Just maybe have fresh perspectives.
She's been in quite a rut lately. It's made it hard for me to watch as well and when I still found time to 'enjoy' her craziness in the past despite her up and down game, because when she's playing well it's quite interesting. Now, it's like she doesn't know what to do out there and just has zero confidence and fight. A real shame because she has some good parts and there are some many areas she could improve if she took time to work on them. Her serve in particular has fallen to pieces, the DF yips caught he rend of 2017 and she doesn't seem to have righted the ship.
