The Houston Base Ball Club's fleet of bus riders collectively came in at an underwhelming #25 on John Sickels/Minor League Ball's new
farm rankings, although he does say "Gradually improving, and there are several players at the lower levels with a chance to develop. Could rank much higher a year from now."
By the way, maybe someone else posted this earlier- but
here is a "revised 1/18" breakdown of the Astros' top prospects by Sickels. Lots of interesting stuff here: he ranks Weiland- who came over with Lowrie in the Melancon deal- 9th, ahead of guys like DeShields, Houser, and Nash; he also feels like the Astros have
rushed guys like Villar and Seaton, which is quite a change. He names Buchanan as a "sleeper guy to watch for 2012" despite his #20 ranking.
