Top 12 prospects: Call-ups preview

Note: The top 12 fantasy prospects (players currently in the minor leagues) for the remainder of 2012 are below. These rankings are a bit different from other prospect rankings, as they are strictly for 2012 fantasy purposes. Not only do talent and recent performance play a role, but potential paths to the big leagues are also factors. All young players in the minors are eligible, including those in "prospect purgatory," those who have exceeded rookie status but are still young, unproven commodities.

With the September call-ups beginning Saturday, this will be the final Top 12 for '12 of the season. On the downside, many of the top prospects have already gotten the call to the majors, so the list of who can help fantasy owners has been pared down a bit. On the plus side, we've finally been given some indication of who is and isn't coming to the majors over the next several days. As such, the rankings have changed dramatically.
