DY has a 50% chance of beating Berrer. If he does beat Berrer, he has a 25% chance of beating Dmitrov.
I like his chances against Dimitrov if he does beat Berrer because Dimitrov has never beaten Young before so there is a mental block.
As far as I know, they've only played once so I wouldnt read too much into their H2H. But, Dimitrov has a one hander, and if Baghdatis had trouble with DYs forehand to his backhand, Id expect the same problems with Dimitrov.
