According to Fangraphs.com, the Chicago Cubs were ranked No. 22 out of 30 minor league baseball systems in 2012. According to those rankings, the organization was deep with regards to right-handed pitchers, yet very thin in the area of catcher and left-handed pitching.
Not much has changed heading into 2013, as the team still lacks a left-handed pitcher or catcher in its top 20 prospects. In fact, there probably isn't even one ranked in the top 40 at this point.
These two areas may be where the Cubs try to focus on building in the 2013 draft, but it is more than likely that the Cubs' minor-league system will be climbing up the ranks in 2013 based on some of the existing prospects.
The Cubs do have some solid players who could be making an impact in the next couple of years. Because of that, the system is probably ranked somewhere in the 10-15 range when compared to the rest of the organizations (depending on who you speak to).
Speaking of the Cubs solid prospects, here are the top-ranked prospects at every position headed into the 2013 season.
