Or: How I spent my Saturday morning.

Last week I tweeted about the success of the Rockies’ farm system in developing actual Rockies. Anyway, I wanted to see if any other team had drafted and developed players as well as Colorado, so, using the 25-man Division Series rosters from MLB.com, I compiled the lists of players who have spent their entire professional careers with their postseason teams.

This includes international free agents, which I realize in the case of guys like Hideki Matsui and Daisuke Matsuzaka is not really about development. Plus, guys like Derek Jeter and Jorge Posada likely only stayed with the Yanks because of the Yanks’ unique ability to pay them. But whatever, it’s just an exercise.

Obviously it’s not a perfect way to assess a team’s farm system, as in many cases, prospects are dealt for players who will help immediately. These are just lists. Don’t read too much into them.

Please excuse the terrible formatting, I’m not great with spreadsheets or WordPress and I have someplace to be in an hour. Anyway, here we go:

That’s not at all fair to the Mets, of course, because Jon Niese, Jose Reyes and Fernando Martinez were on the disabled list at the end of the year. But life isn’t fair to the Mets.

I, for one, would like to see a team filled up with homegrown players, if only because that’s the most inexpensive way to fill out a roster. The Angels, for example, save money to spend on top-flight free agents — often foolishly — by filling in the spaces around the big-ticket items with players they developed themselves.

Now, it’s off to brunch with some Australians. Here’s hoping they don’t force me to eat Vegemite.
