Well Monica is 9-4 this year and Sammy is 1-5. I'm sure that hasn't gone unnoticed by the punters and bookmakers. Not saying Monica will win, but given the form of the two players it is certainly understandable that people think she has a decent shot. Personally, I'm trying hard not to let myself get overoptimistic because I know how unpredictable tennis can be and I don't want to let myself be too disappointed in the event Monica loses.
Reallistically it's probably a 50/50 match meaning the value for Monica is okayish but nothing that screams amazing value.
