Brett Pill and Brandon Belt, to be specific. Although players like those two, and others including Buster Posey, have panned out well for the Giants, not every prospect will have the same effect.
Here are some highly touted prospects who may not make as big of an impact as most people expect.
The Giants have been struggling behind the dish since Posey was injured earlier in the year.
Brian Sabean wasted no time in calling up Hector Sanchez from Triple-A , who is young and was pretty effective in his short minor league career.
Although Sanchez is well-rounded, he hasn't shown signs of being anything special. He most likely has the talent of a major league backup catcher, and won't see much time on offense with the Giants.
Now, I'm a fan of Brandon Crawford.
He has excellent defense and a really likeable personality. The problem is that he isn't talented offensively.
Crawford will show occasional signs of major league talent with his bat, but it's seldom. I think he's good enough to stay around a while, but he'll never be that primary shortstop that the Giants are hoping for.
Granted, Conor Gillaspie is still a young guy, but he's been given opportunities at the major league level and hasn't done anything with them.
There isn't really room for him at third base anyway, when Pablo Sandoval and Brett Pill are playing so well. Whenever I think about a situation where Gillaspie could become a productive major league player, it doesn't end well.
Regardless of how highly touted Gillaspie is, he'll need a lot of good luck if he wants to be successful in MLB.
