Mickey Jannis wasn’t allowed to throw a knuckleball when he was in the Rays system. That was in 2010 and 2011, his first two seasons of professional baseball. He’s a Met now, and the butterfly is out of his back pocket.

The bridge between Tampa Bay and New York was unaffiliated. Jannis pitched in the independent Frontier and Atlantic leagues from 2012 to 2014. Non-baseball options were available — the 28-year-old righty has a degree in business administration from Cal State Bakersfield — but he wasn’t ready to give up his dream. Not when he had a secret weapon to employ.

Flummoxing hitters with his floater, Jannis put up a 1.18 ERA for the Long Island Ducks early last summer. Subsequently inked to a contract by the Mets in July, he proceeded to hold his own in 11 appearances between high-A St. Lucie and Double-A Binghamton.

Jannis discussed his atypical journey, and the evolution of his equally atypical go-to pitch, at the tail end of the Arizona Fall League season.

———

Jannis on knuckleball commitment: “I mentioned it to (the Rays) toward the end of my second season, when I was with Hudson Valley, but I wasn’t able to throw it in a game. My manager, Jared Sandberg, was kind of all for it. He was, ‘Yeah man, that’s good enough to throw,’ but it just didn’t work out to where I could. I only threw it on the side.

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.

‘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.

1. Tim Anderson, SS (Profile)

KATOH Projection Through First Six Seasons: 6.0 WAR
Dan’s Grade: 55

At the plate, Anderson’s 2015 at Double-A strongly resembled his 2014 at High-A. He struck out in over 20% in his plate appearances, walked in less than 5% and hit for an unremarkable amount of power. While he improved his walk rate to near-respectability — from 2% to 4% — he sacrificed a chunk of power in the process. Last year, however, he complemented his relatively empty .300 average with a boatload of steals, which speaks to the 22-year-old’s athleticism. Anderson’s undeveloped bat still gives KATOH some pause, but shortstops with top-notch speed don’t need to hit much to be productive.

In something of a curious trade, the Rockies flipped Corey Dickerson to the Rays for Jake McGee. Those two players were the headliners of the deal, but they weren’t the only two players involved. Also changing hands were third baseman Kevin Padlo and hard-throwing righty German Marquez, who head to the Rays and Rockies, respectively. Here’s what my fancy computer math says about the minor leaguers involved.

Kevin Padlo (Profile)

The Rockies drafted Padlo in the fifth round out of high school less than two years ago, but he wasted no time putting up gaudy numbers in the low minors. Padlo graded out extremely well by an embryonic version of KATOH and, nearly a year and a half later, his enticing combination of power, speed and youth still tips the scales. He placed 37th on KATOH’s newly-minted prospect list, with a projected 5.9 WAR through his first six years in the show.

Back in November, I published a top-100 prospect list that was generated by my KATOH projection system. Since that time, I’ve done some tinkering to improve the model. So even though we just did this, like, barely even two months ago, I’m back with another list for you. In addition to yielding lower AICs and R^2s and whatnot, this version also feels better in terms of the projections themselves. There aren’t as many head-scratchers as before, which suggests I’m moving in the right direction. There are still players who feel too high to me and others who feel too low to me, though I’d argue that’s not always necessarily a bad thing.

There’s still room for improvement. That will always be the case. But I think I’ve reached a point where I’ve gotten most of the low hanging fruit. This isn’t to say I’ll stop trying to make improvements, but don’t expect anything drastic anytime soon. This is the version I’m prepared to go to war with in 2016 (for now, at least). It’s not perfect, but I think it’s a sizable step in the right direction. Below, you’ll find a brief writeup of the changes, followed by a brand new top 100.

Moving Beyond WAR Through Age-28

In the past, a few commenters rightly pointed out that projecting a WAR total through age-28 wasn’t all that informative for some prospects. For a guy who’s already 25, his WAR through age-28 captures at most three years of team control, while it might capture all of a 21-year-old’s control years. In this iteration, I made my output a bit more flexible. For players 22 and younger, I still forecast WAR through age-28. But I expanded my horizons for players 23 and older, and now project the next six years. So 23-year-olds get a WAR thru 29, 24-year-olds get a WAR through 30, etc.
