Its an average draw, first two rounds are winnable, and Sharapova is tough, but on clay Mary has a good chance. GOod luck Mary!
Now, if Mary was injured in Berlin, why is she playing doubles again? and when was the last time Mary played a singles and a doubles match in one day, and came back to win her singles match the next day. Only once this year, I think... I love to see Mary in doubles, but please Mary atleast try a week without doubles and see how it goes. Last week is a perfect example, she plays two matches on wednesday... comes out on thursday against an opponent she beat easily in their last 2 encounters, and makes more UE's than her last matches. I mean c'mon, its not just a coincidence!
