Serena play bad on this tournament, but I will play this more on feeling. I hope the scenario as in Madrid, Serena slipped against Azarenka then demolished the defensive Navarro, this torture against Stephens and against Azarenka was against hitter against Friedsam bad day, and it's enough. I expect finaly one good match from Serena and easy win.
Errani against Goerges 5 winners and 3 neforsirane. Only with 8 points after 1 hour .Serena will have many chance on Errani first serve, not to talk about the second, the average speed of service against Goerges 118KM / H, the fastest 139, Serena average 155, the fastest 196 against Stephens.
h2h is 8:0 for Serena,last 4 matches 15, 20, 13 and 15 games in the match. If Serena finaly play like she know I dont see how sara can take more than 6,7 games in this match.
