Flashback to February of 2006. Lindsay Lohan has never been to jail, Steve Irwin’s alive and well, and we still have three years of Bieber-free living to look forward to. More importantly, though, Baseball America has just put out its annual top 100 prospect list.

Now that a decade’s passed, and we know how each of these players turned out, let’s look back at some of these players’ prospect years. Perhaps there are lessons to be learned — statistically or otherwise — from their case studies that might be useful in evaluating today’s prospects. Keep in mind that these players are all just anecdotes. They represent merely a few data points among thousands, and therefore shouldn’t be used to draw any sweeping conclusions. But still: real-world examples are always fun, and names and faces are a great way to bring macro-level trends to life.

Below each name, you’ll see three WAR figures. The first is that player’s historical KATOH forecast — that is, what KATOH would have projected given the relevant prospect’s minor-league numbers. The second was calculated using the formula derived by Jeff Zimmerman in this year’s Hardball Times Annual applied to each player’s 2006 BA ranking. The third is that player’s actual (positive) WAR total throughout the period of time forecasted by KATOH. (So for players 22 and younger, that’s thru age-28. For players 23 and over, it’s the first six years.)

Essentially, you have KATOH’s projection, BA’s projection, and what actually happened. I tried to glean some sort of lesson from each of these case studies, even if the lesson wasn’t particularly ground-breaking.

1. Delmon Young, OF (Profile)

KATOH: 13.9 WAR
BA: 20.3 WAR
Actual: 3.6 WAR

Just like everyone else, KATOH was all in in Delmon. It was kind of hard not to be. Young hit .322/.388/.538 as an 18-year-old in A-Ball, and then slashed .315/.354/.527 between Double-A and Triple-A. And he stole bases, too. He had it all, or at least it looked like he did.

His one flaw was his plate discipline. Both his strikeout and walk numbers left a little to be desired, but dwelling on those numbers feels like nitpicking. His 7% walk rate was certainly acceptable, and his 19% strikeout rate wasn’t terribly concerning (even considering that 19% then might be equivalent to 22% now). When a player is so good at everything else, you can let things like that slide. You kind of have to, or else you’d be down on nearly every prospect.

As you know, Delmon never panned out. The plate discipline was the biggest culprit — although his weight problems certainly didn’t help, either. As of this writing, Young is a 30-year-old who’s been without a team for the better part of the last year. He was a replacement-level player or worse for most of the last decade.

Lesson
I guess the takeaway is to be wary of hitters who have great tools and minor-league numbers, but also possess an unrefined approach at the plate. Although, I’d be lying if I said I could have seen this coming. The strikeout rate was a warning sign, but the truth is that 19-year-old Delmon Young gave us little warning that we were in for a decade of replacement-level play. More often than not, players as talented as Young make the necessary adjustments. Sometimes they don’t.

Yesterday, lead prospect analyst Dan Farnsworth published his excellently in-depth prospect list for the Kansas City Royals. In this companion piece, I look at that same Kansas City farm system through the lens of my recently refined KATOH projection system. The Royals have the 20th-best farm system 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. Cheslor Cuthbert, 3B (Profile)

KATOH Projection: 4.1 WAR
Dan’s Grade: 40+ FV

Cuthbert hit .277/.339/.429 as a 22-year-old in Triple-A last year, which earned him a late-season cameo with Kansas City. Cuthbert likely won’t be a star, but he makes a lot of contact, plays a semi-premium defensive position and is young enough that he still has time to improve. Statistically, he looks like a future everyday player, and those don’t grow on trees.

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.

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.

Yesterday, I utilized my KATOH projection system to rank the 30 farm systems. By my math, the Milwaukee Brewers are the top dog. And it isn’t particularly close. Here’s a graphical representation of each team’s cumulative projected WAR according to KATOH.

The Brewers farm system outpaces everyone else’s by a fairly wide margin by this metric. That’s interesting in and of itself. But the path David Stearns and company have taken to put their farm system in this position is perhaps even more interesting.

For one, they’ve acquired a large chunk of their minor league talent in the very recent past. Orlando Arcia, their consensus top prospect, has been around for a few years; but many of the others are very new additions. In fact, KATOH’s #2 through #8 prospects all joined the organization within the past seven months. That’s Ramon Flores, Jacob Nottingham, Brett Phillips, Josh Hader, Isan Diaz, Zach Davies and Javier Betancourt. Domingo Santana would fall in that group as well were he still prospect eligible. They’ve also added Rymer Liriano, Keon Broxton, Garin Cecchini, Jonathan Villar, Adrian Houser, Bubby Derby (who I’m still not convinced is a real person) over that same period. Not to mention lower-tier prospects Freddy Peralta, Trey Supak, Colin Walsh, Zack Jones, Carlos Herrera, Daniel Missaki and Manny Pina.

‘Tis the season for prospect rankings. With little else going on in the baseball world, prospect writers typically spend the month of February releasing and discussing ordered lists of prospects and farm systems. Even within the past hour at this very site, our own Jeff Zimmerman published a farm-system ranking derived from the scouting grades produced by Baseball America.

This year, I showed up to the party a little early by putting out KATOH’s top 100 list last month. I still have more to give, however. And here I present you with KATOH’s organizational rankings.

My methodology for compiling this ranking was pretty straightforward: I simply aggregated all of the KATOH forecasts by team. Still, there a few caveats worth mentioning.

• To be considered in this exercise, a player must have recorded at least 200 plate appearances or batters faced in 2015. KATOH derives its forecasts from minor league stats, so it can’t really formulate an opinion on players who didn’t play much in 2015. As a result, many of the players who were drafted in 2015 are omitted.

• This exercise only considers players projected for at least 1.0 WAR over their first six years in the big leagues. Ideally, I’d consider all prospects, but that would involve verifying the teams for thousands of mostly nondescript minor leaguers. That obviously taken some time. This one-win threshold cuts pretty deep into a team’s farm system. The average team has 18 players above this cutoff, while none have fewer than 10. That feels like more than enough for these purposes.

• KATOH tends to favor hitters over pitchers, especially on the high end. So this analysis likely favors organizations with farm systems that are hitter-heavy over those that rely more on pitchers. This is likely because a pitcher’s stats capture a smaller portion of his future potential relative to hitters. Factors like velocity also very important when it comes to projecting pitchers.

• And as always, stats don’t tell the full story. This is the output from a flawed statistical model that fails to take into account many of the factors that go into evaluating a prospect. If an organization has a lot of raw, toolsy prospects, it’s likely to be underrated here.

1. Michael Fulmer, RHP (Profile)

KATOH Projection: 3.8 WAR
Dan’s Grade: 50 FV

Fulmer enjoyed a breakout season with the Mets last year and kept it going after he came to the Tigers in the Yoenis Cespedes deal. Both his strikeout rate and walk rate improved as he made the jump from High-A to Double-A in 2015, giving him the lowest ERA — and second lowest FIP — in Double-A last year.

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.

1. Jose Peraza, 2B (Profile)

KATOH Projection: 14.9 WAR
Dan’s Grade: 55 FV

Peraza burst onto the prospect scene in 2014, when he hit .339/.364/.441 between High-A and Double-A. His high BABIP came back to earth a bit in Triple-A last year, but was still roughly a league-average hitter. His .293/.316/. 378 showing wasn’t bad at all for a 21-year-old. Peraza is an interesting prospect due to the outlier-ness of many of his attributes. For example, both of the following sentences are accurate. One: he’s a 70-grade runner who makes tons of contact, is a strong defender up the middle, succeeded in Double-A as a 20-year-old, and held his own as a 21-year-old in Triple-A. And two: he’s a second baseman with minimal power who never walks and has been traded twice in the past seven months. There are clearly pros and cons to Peraza’s profile, but when fed into KATOH, they yield a very favorable projection. I’m always skeptical of the projections for outlier cases like Peraza, so let’s turn to the Mahalanobis comps for more clarity.
