With the 2012 minor league season winding down, it's a good time to re-assess. Every year, multiple media outlets spend time and energy compiling a list of players they deem to be the next impact players in the big leagues. Here at BaseballHQ.com, our 2012 Top 100 Prospects list was published on January 20. And every year, players rise and fall from these rankings as the season goes on.

As we enter the homestretch of the 2012 season, teams will be able to expand their rosters to 40 players beginning next week. Some September call-ups will have little fantasy or real world impact, but there are some top notch prospects that could help clubs as they make a push towards the playoffs or start to rebuild for 2013 and beyond. Savvy fantasy owners will need to keep an eye on these call-ups, many of whom offer both risk and reward. This week we look at possible impact call-ups in the NL.

With just a few weeks to go in the 2012 minor league season, we take another tour around the minors to see who is hot and who is not. Next week we begin to take a look at possible September call-ups. On 8/17 we take a look at possible AL call-ups, followed by the NL on 8/24.

Wrapping up the final 24 hours of the trade deadline, prospect style.
