Farm Strength Index
MLB's Best Farm Systems, Recalculated Daily
To calculate which farm systems are really the strongest in baseball, we use a simple formula that measures how highly each team's best prospects are ranked within the overall prospect population. Because scores only have value relative to the fixed overall talent pool, we call it the Farm Strength Index.
Like our live top prospect rankings, we remove human nature and bias by calculating each position: no human being decides to place any team higher or lower than any other. These farm strength rankings recalculate each day to reflect the evolving strength of each minor league system.
In approximate human-friendly terms: a farm strength over 70 is excellent, 60-70 is good, 50-60 is probably fair, and less than 50 would usually be considered poor.

Because these scores are based on our Scouting Book Combine Ranking, which uses many other publications as well as our own weights, these farm-wide scores will reflect the same biases (for example, rankings value hitting more than fielding, especially for positions where offense is particularly rare, such as catcher.) Also, because our prospect rankings change every day to reflect their own complex recalculations, the overall farm ranks will also change daily, though less dramatically.
