Yesterday, lead prospect analyst Dan Farnsworth published his excellently in-depth prospect list for the Los Angeles Dodgers. In this companion piece, I look at that same LA farm system through the lens of my recently refined KATOH projection system. The Dodgers have the third best farm system according to KATOH, trailing only the Brewers and Astros. They have the most projected pitching WAR and the most WAR coming from 3.5+ WAR players.
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. Corey Seager, SS (Profile)
KATOH Projection: 12.3 WAR
Dan’s Grade: 65 FV
Seager showed what he’s capable of last September when he slashed .337/.425/.561 with the Dodgers. Prior to that, he hit a strong .278/.332/.451 in Triple-A. Seager’s 2015 numbers weren’t particularly gaudy, but he did manage to cut down on his strikeout rate, which was previously the one flaw in an otherwise promising stat line. Shortstops who hit that well at such a young age are few and far between. That’s why Seager has the chance to be a special player.
