with all due respect ...
Caroline Wozniacki is -500 versus Sorana Cirstea is a bad play in my opinion, for these reasons:
1. Wozniacki lost first set to Dushevina, a so-so Russian player in the first round and barely recovers with a 7-5 second set before winning;
2. Cirstea is in good form, beating Cornet easily in the second round and was good before Roland Garros,
3. This is Roland Garros where the likelihood of non clay-court top players (for whom Wozniacki is) losing in upsets is the highest among the 4 Slams;
-500 might win but i think it is not value above -300 here, instead i will play Cirstea for a juicy +425
