Last week, lead prospect analyst Dan Farnsworth published his excellently in-depth prospect list for the Tampa Bay Rays. In this companion piece, I look at that same Tampa farm system through the lens of my recently refined KATOH projection system. The Rays have the eighth-best farm system in baseball according to KATOH.
There’s way more to prospect evaluation than just the stats, so if you haven’t already, I highly recommend you read Dan’s piece in addition to this one. KATOH has no idea how hard a pitcher throws, how good a hitter’s bat speed is, or what a player’s makeup is like. So it’s liable to miss big on players whose tools don’t line up with their performances. However, when paired with more scouting-based analyses, KATOH’s objectivity can be useful in identifying talented players who might be overlooked by the industry consensus or highly-touted prospects who might be over-hyped.
Below, I’ve grouped prospects into three groups: those who are forecast for two or more wins through their first six major-league seasons, those who receive a projection between 1.0 and 2.0 WAR though their first six seasons, and then any residual players who received Future Value (FV) grades of 45 or higher from Dan. Note that I generated forecasts only for players who accrued at least 200 plate appearances or batters faced last season. Also note that the projections for players over a relatively small sample are less reliable, especially when those samples came in the low minors.

1. Jake Bauers, 1B (Profile)
KATOH Projection: 8.2 WAR
Dan’s Grade: 45 FV
Bauers spent his age-19 season squaring off against High-A and Double-A pitchers, and more than held his own. Bauers didn’t show any glaring weaknesses offensively, and rode a 14% strikeout rate to a .273/.347/.422 batting line. Bauers doesn’t have the power of a traditional first baseman, but he excels in every other offensive area. Considering how young he’s been for his level, that’s quite an accomplishment.
