Ive noted some big movers over night in terms of odds
Lopez was the 8/11 jolly last night, at this momment melzer is the 8/11 fave..
S.Bohli vs Vanek were both $1.83 yesterday morning now bohli stands at $1.40 (big move that one, i want to know more about this bohli, is any good?)
Nishkori has come in slightly from 7/4 to 11/8
Berrer is drifting for some reason
De Heart is getting some attention- anyone know anything about this guy?
Lopez has done jack for most of the year, while Melzer has been picking himself up for the last month or so...so certainly form, and confidence, is with Melzer at the moment.
Off the top of my head, Bohli was putting together some good performances in the challengers and has made good progress this year? Vanek is never one for the faint-hearted, and that is not just considering his tennis, if you know what I mean.
Probably more about fading Monaco on grounds of lack of preparation/surface etc, although it isn't like Nishikori has done anything of note recently, either.
For some reason there is a lot of love for Acasuso (even if he will eventually win)...don't think it is anything more than that tbh.
Player forums might give you some answer to that (not checked, myself), but otherwise I wonder if it is more about fading Rochus on grounds of form/fitness than anything else?
My 2 cents, anyway.
