Sadly this was an expected loss, i didn't see the match, so maybe i am wrong, but i definitely believe that Caro is back to her messy self of last summer-spring when didn't really know what to do on court and when to be aggressive and when not.
Honestly i believe that will just be her standard from now on if piotr won't leave
