One of the big questions every year is what prospects are going to get called up to the major leagues and make a difference for the team. Last year, the Astros saw a number of prospects come up and make a difference on this team.
Bud Norris was a key starter in the rotation for the Astros the whole season and he was joined later in the year by players like Chris Johnson, Jason Castro and Brett Wallace. Generally, teams don't see this many prospects come up and play key roles on their club, but by midseason the Astros were in full-blown rebuilding mode.
The other problem with bringing up that many young players is that it depletes your farm system. After adding in poor drafting from the Astros organization for a few years, there aren't many prospects who are ready for the majors within the farm system. Here are five players currently in the Astros organization who could play a role in the major league club sometime in 2011.
