How old is your Double-A team? by Jeff Sackmann August 8, 2009 In my article earlier this week, I looked at the age distributions of 2009 Triple-A teams. It was easy enough to generate a similar report for 2009 Double-A teams, so here it is. I’ve included the average age of the organization’s Triple-A affiliate in the rightmost column.

Conventional wisdom, or some variation thereof, probably does a good job of explaining why this is. Triple-A teams are, more than anything else, extended benches. Thus, if a team wants veterans to plug in at a moment's notice, their AAA squad will skew older. That preference will probably not affect the age of the Double-A affiliate very much, if at all. Perhaps such a team would be more likely to stash a veteran catcher (think Max St. Pierre, maybe) at Double-A, or maybe a veteran signed out of the indy leagues would spend time in Double-A because the AAA roster is full. But that's about as far as it goes. But Double-A teams are generally built around prospects, and the makeup of the roster is more dependent on who happens to be in the system. While a lot of free-agent signings go into the formation of a Triple-A roster, most Double-A non-prospects are organizational soldiers (often with their original org) who have survived. If a team has a lot of prospects at a particular level, that affiliate will skew younger. If the club's prospects are mostly younger and/or graduated, Double-A will be unusually full of filler, including some free agents and minor league Rule 5 picks. The Brewers, whose AAA team is young and whose AA team is (relatively) old, are a good example of this.
