Post-2018 Farm System Rankings
Today, I’ve published a pair of posts in which I attempt to estimate the present-day value of prospects, both in terms of WAR and dollars. With that work complete, the logical next step is to turn away from the value of specific prospects and towards farm systems as a whole.
One can get a sense of the stronger and weaker systems just by eyeballing the rankings produced by Eric Longenhagen and Kiley McDaniel. What the prospect-valuation data allows us to do, however, is to place a figure on baseball’s top-800 or so prospects, creating a more objective ranking based on the grades assessed to each player here at FanGraphs.
These rankings provide a current snapshot of the farm systems before Longenhagen and McDaniel embark on their winter-long reveal of team prospect rankings. (The first post in their offseason series will appear this week.) As noted, the methodology for valuing prospects based on their grades is explained in my last two posts on the subjects:
Keep in mind, these values are based on the current CBA, where players receive a minimum salary for roughly three years and then have three (or four) years of arbitration before reaching free agency after six full MLB seasons. Players are generally underpaid compared to their value on the field during these seasons, which is what creates the high present-day values and partially justifies the high value placed by teams on prospects when executing trades.
