Value generated by Brewers international signings

At the Phillies blog The Good Phight, we recently published a series on the success (or lack thereof) of the Phillies' drafts and international signings over the years, as well as a more holistic overview. Since I don't know that the comparison on international signings in particular is available elsewhere, I thought I'd do a brief version for each team.

About a quarter of all current production in MLB (by WAR) is generated by players who were signed as international free agents (IFAs) — either as teenagers who then rose through farm systems, or established pros ready to step directly onto major league rosters.

This looks at an arbitrary time frame of the 30 years 1990 through 2019, and uses WAR (from fangraphs.com) as a quick and handy measure of major league value. The WAR shown represents a player’s total career production to date, regardless of what teams he was with at the time. All of a player's career WAR is counted for the team that signed him, in the year they signed him. Any kind of ranking like this will favor the teams who were successful earlier in the period, since those players have had a chance to produce all or mostly all their career WAR.

We will start with the team that's ranked 30th in WAR produced by its IFAs over this time period, and work our way up, and that 30th team happens to be Milwaukee. This is not meant to pick on the Brewers, someone has to be last.

The first graph shows where the Brewers’ IFAs fall for each year’s class: the green line is the team whose signings from that year have produced the most WAR so far, yellow is the team with the lowest WAR produced from that year’s class, and black is the average for the 30 teams.

Again, each point along a line represents the total career WAR produced by players who were signed that year.

The next graph is similar to the above, except at each point we look at all the signing classes combined, from that year through today. So for example, for all IFA signings since 2000, the team whose signings produced the most WAR has had 235, the average is 70 WAR, and the Brewers’ IFAs over that time are near the bottom with 23.

The graph includes the Brewers' ranking for all IFAs since 1990 (i.e. 1990 through 2019), and then we'll cut the time frame in half and rank total WAR for all signings since 2005:

For those who prefer numbers, these are the tables behind the graphs:

Below is a graphical view of their best signings of the last 30 years in terms of WAR produced to date. The more successful ones are broken out, and any remaining ones are included in the light green boxes:

So Alcides Escobar, Wily Peralta, and Nori Aoki have combined for a total of 24 WAR in their careers so far, and all other Brewers signings have combined for a total of -1.

This is the complete ranking of the 30 teams (plus the average), and we'll reveal team names as we go up:

Spoiler alert -- Next: Royals
