Pretty impressive for K Tuck and Yordan seeing as most of those guys at the top of the list played at the one remaining hitter friendly affiliate in the system. Its nice not seeing a bunch of non-prospects at the top of the list like during the Lancaster era.
Astros have a lot of good players blocked by even better players in the show. That causes something of a logjam at the higher levels, especially triple A.
Pitching does get better which will affect walks and strikeouts. However, power numbers tend to go up more based on a highly unscientific look at the minor league stats of guys on the Astros. In addition, there is some selection bias as guys that hit well get moved up. If Astros AAA team played at a neutral environment, I'd expect that list to be mostly AA and AAA players.
Actually not bad. That list features a hall of famer (Altuve), one of the best hitters in the league (Martinez), a guy who was a decent everyday 3B for a few years (Johnson), and a AAAA OF (Goebbert). The real ugly would be a 2007 list.
2007 wasn't that bad. Had the same future HoFer as 2010, Pence barely made my arbitrary 100 PA cut off, a 1.9 career WAR Jason Lane & a non-HoF Tim Raines
The big change in the 2007/2011 lists is to compare the ages of the players to the current one. Makes a big difference.
