i hope you guys are talking about a different montero, not jesus montero
. there is zero chance that he gets called up anytime soon. cervelli is serviceable right now and a solid defensive catcher and posada is going to be cleared to return to C soon. also, montero has yet to find his bat in AAA, sure he's been solid the past 5 games finally, hitting over .300 and 5 doubles, but thats only 5 games. It will take a lot for montero to be called up this year.
same with dom brown. the phillies have werth, ibanez, victorino, and francisco at the big league level, and if any of those went down with an injury, john mayberry would get the callup, not brown. now, if the phils continue to struggle and they decide to deal werth at the deadline, then i could see brown get the callup to kind of jumpstart the offense and bring some hype back but i dont see that scenario playing out. The phils are still the best team in that division and will figure out their slumping offense.
if i had to guess, maybe chris carter of the A's, not sure what other top prospects are really close to a promotion. desmond jennings is probably the most mlb-ready top prospect at the moment but with s-rod and brignac hitting very well, and bartlett returning from the DL wed. it is looking like either 2 injuries or a trade are going to have to happen for jennings to get a callup.
