Baseball America came out with its minor league Organizational Standings for 2009.
Predictably, the Astros ranked 30th with a cumulative .420 winning percentage (320-442). But with a disclaimer:
Intuitively, it would seem a more difficult task for an organization to stock seven minor league clubs with talent. And we see that only the Mariners among the lucky seven managed to crack the top half of the standings. Note that the Astros and Rays each added a GCL affiliate for this season.
The newly formed GCL Astros had the 2nd-worst winning percentage in all of minor league baseball at 18-38, and the Tri-City ValleyCats clocked in at 6th-worst with a 27-48 record.
