The main purpose of the minor leagues is to identify, filter, and develop talent for the big club. The closer you get to the show, though, the less clear that purpose is. At the Triple-A level in particular, it's hardly a prospect paradise.

The various goals of Triple-A result in some weird lineups. On Tuesday, the Nashville Sounds, for instance, had Corey Patterson, Alcides Escobar, and Joe Koshansky batting two-three-four in their lineup. I'm not sure how to characterize Patterson's role at this point in his career, so let's just say that those guys don't exactly serve the same purpose for their parent club.

In fact, we can summarize some of those functions as follows:What interests me is the way different clubs balance these three competing priorities on their Triple-A rosters, and how they fill out the first and third groups. Everybody loves an underdog story, especially when the underdog turns into a quality setup man working for the major-league minimum.

A surfeit of savvy


Some teams seem to like veteran presence in their Triple-A clubhouse. After all, why waste a pick in the minor league portion of the Rule 5 draft when you can sign Abraham Nunez instead?

To get an idea of which teams have which predilections, I ran some numbers. I took the age of all players who had 30 or more at-bats or batters faced for each Triple-A club this year. I've included the average age, the median age, the average age of batters and pitchers, and the number of players who fit into each of three age groups.

Here are the results:

That, my friends, is a lot of data. There probably isn't much meaningful to say about the middle 15-20 teams on the list. The difference between an average age of 26.7 and 27.5 isn't worth much. It is interesting to see where your team fits on the scale, though.

Let's go to the bullet points to highlight some notable findings:Clearly, the age distribution of a Triple-A affiliate isn't some hidden secret of success. In every segment of the table above, you'll find major league clubs having great, middling, and poor seasons.

As long as you have some MLB-ready pitching ready to step in and a few prospects to keep fueling the organization, maybe the "filler" really is just that. If so, consider this an open letter to Dayton Moore. I can fill a roster spot like nobody's business. And I'm still under 30!
