Apart from the the mental bloke, I think Sharapova loses to Serena easily could also be because of her style of play. Maybe Sharapova's style of play doesn't work against Serena. Could be a reason.

I would say it is a mix of both honestly. It is really weird though, Maria can destroy anyone but when she faces Serena she gets destroyed. You would expect Sharapova to give her a little bit more of a challenge but she just gets destroyed. Other players actually give Serena more of a challenge than her.
I guess when Sharapova goes up against Serena, she comes into the match honestly believing that she doesn't have a chance at all to win.
