KATOH Projects: Colorado Rockies Prospects
Previous editions: Baltimore / Boston / Chicago AL / Chicago NL / Cincinnati / Cleveland.
Earlier this week, lead prospect analyst Dan Farnsworth published his excellently in-depth prospect list for the Colorado Rockies. In this companion piece, I look at that same Colorado farm system through the lens of my recently refined KATOH projection system. 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. Trevor Story, SS (Profile)
KATOH Projection: 7.2 WAR
Dan’s Grade: 50 FV
Story’s prospect trajectory resembles a bathtub curve — which is to say it’s gone from high to low and back to high again. Drafted 45th overall back in 2011, he got off to a strong start in the low minors, but hit a wall as soon as he reached High-A. Story got back on track in 2015 when he hit .279/.350/.514 between Double-A and Triple-A with 20 homers and 22 steals. Story was one of the top offensive performers in the high minors last year, which is mighty impressive for a shortstop. His 25% strikeout rate is cause for concern, but is largely outweighed by everything else he does well.
