It's the same old Azarenka: sooner or later she'll lose her temper, push over an orphan and brutally murder a seagull.
Her behaviour on-court has been like this all year actually. She's not cursing, imploding and etc as fast as last year. Last year, she would definitely not be smiling when she missed a shot or when a linesman made a bad call. I think Sumyk really helped her a lot with it during the off-season, but it's not perfect yet.
