Earlier this week, lead prospect analyst Dan Farnsworth published his excellently in-depth prospect list for the Houston Astros. In this companion piece, I look at that same Houston farm system through the lens of my recently refined KATOH projection system. The Astros have the second-best farm system according to KATOH, trailing only the Brewers. Their system lacks star power, but is easily the deepest. That’s why this post has way more words than you probably care to read.
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. AJ Reed, 1B (Profile)
KATOH Projection: 7.1 WAR
Dan’s Grade: 60 FV
Reed might have had the biggest breakout of any minor leaguer in 2015. Minor league pitching was no match for his mammoth power and copious walks, as the 22-year-old hit .340/.432/.612 between High-A and Double-A last year. If you’re looking for something to be concerned about, it’s Reed’s 20% strikeout rate. While that’s not alarmingly high, it’s a tick above average, and hints that he might have a tough time making contact against big league pitching. But otherwise, all systems are a go. It isn’t often that KATOH gets excited about a first base prospect, but it’s all in on Reed and his gaudy power numbers.
