Which shatters the idiotic "fixing" consipracy theory vomited by ScentOfDefeat and others of his ilk on this board.
I've said this time and again" when Sharapova walks out on a court with Serena, she genuinely believes she can win. Her game, behavior and posturing all scream that to anyone who has watched this player over the years. Believing alone may not be enough, but for anyone with any measurable skill to g along with it, it could be enough to lead to victory.
So, I will go ahead and say Sharapova in three, but she will not make it to week two.
As for Serena, if she loses, I predict she will radically alter her training and possibly skip AO 2020, in order to be fit/focused enough to have great chances at the other three 2020 majors.
