Here's a few options to consider for tomorrow (more stars = more likely to win. In my opinion all of these will win and at least one of the favourites below will lose):
Cetkovska -2.5 *****
Anderson -1.5 ***
Scheepers -2.5 ****
Raonic **
Arn +7.5 *
Sela +6 *
Baghdatis **
Kuznetsova -2.5 **
Muguruza-Blanco *
Favourites that are more likely to lose than the odds would indicate:
Troicki **
Montanes *
Ivanovic ***
Another thing: if your shop offers matches from Tunis (ITF), watch for Ana Savic (just bet her every time, including to win the whole thing at probably 150:1), you'll thank me later. She's a completely unknown player on a 21-0 match bulldozing streak. There's one player I spotted recently that could wreck havoc at the French Open qualies and in the early rounds of the main draw this year. Her name is Maryna Zanevska. She has recently won Tenssenderlo (clay) as a qualifier, and was a finalist in Grenoble (hard), also as a qualifier. Mona Barthel needed three sets to shake her off in the beginning of the year on hard court, and I believe Zanevska is even better on clay.
And on Monday, Savic straight-setted her (while being a 5:1 dog) like it was nothing...
Ana Savic. You heard it here first.
