Wang very well could but if it isn't Sabathia it should be Beckett. Even Escobar is a better choice than Wang. Santana would be a great choice but if think (in a figurative sense of course) like the voters do, Santana has too many losses.
I just think there is nothing spectacular about Wang. He doesn't strike batters out, his ERA is really high for a CYA winner (14th in the AL), he doesn't do a great job at keeping runners off base, and he probably won't get 200 innings (IMO something that is almost a requirement to me).
No bias there about Francona, right?
