I must take this before bookies droped odd. Sloane in the first round against Scheepers had a lot of luck, passed in two sets while being shown I can say very bad tennis, losing quite a kickoff times, overall crawled through two extended sets, and very easily could lose both.She , generally. in 2015. shows very poor parties – few victories that she made it against weaker players ranking of the form (Niculescu, Espinosa, Scheepers). She also have 4 loses (Davis, Azarenka, Watson, Larsson).
On the other side , Kerber not brilliant, but she has a positive balance. Win against Kuznetsova, Stosur, Muguruza..surely good tennis players.Kerbercan play a very aggressive, attack, and simply in any scenario I do not see may surprise, this would Kerber should have solved smoothly, probably in two sets. But, i go surely here and will take regular win.
Good Luck!
