SO/BB Ratio for Position Players

I don't think anyone will be surprised to see in black and white that Humberto Quintero strikes out a lot more than he walks or that J.B. Shuck walks a lot more than he strikes out.  But how is the rest of the group doing?  I included the national league average so you can see who falls above and below that line.

Here's a look at the 2011 SO/BB Ratio for all position players in the Astros system.  If the player played for both the major league club and a minor league club, both sets of stats are included.  For those players traded to the Astros during the season, only stats while with the Astros organization are included.  The lower the number, the better.
