Prospect stock is a funny thing that can vary wildly.
Although it is wrong to react too much to one bad start or one hot streak at the plate, a good or bad couple of months -- with corresponding scouting reports -- can affect how the industry sees a player's future.
Every year, hundreds of players fail to live up to expectations.
Here's an All-Star team of players who hurt themselves early but have regained their prospect status.
Catcher: Jesus Montero, New York Yankees
Montero slugged .517 in Triple-A as a 20-year-old in 2010, but he failed to repeat those numbers this year, with scouts noticing some effort issues at the plate and behind it.
His frustration is somewhat understandable, considering that there is no obvious opening for him in the Bronx, but he has bounced back since the All-Star break, slugging .515 in the second half with eight home runs in 130 at-bats now that he has stopped tinkering with his swing.
The bad news is that he's still not seen as a catcher in the big leagues, so an offseason trade might be his best bet for a big league shot.
