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.

Yesterday, lead prospect analyst Dan Farnsworth published his excellently in-depth prospect list for the Chicago Cubs. In this companion piece, I look at that same Chicago farm system through the lens of my 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 age-28 seasons, those who receive a projection of at between 1.0 and 2.0 WAR though their age-28 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. Albert Almora, OF (Profile)

KATOH Projection Through Age 28 (2015 stats): 12.7 WAR
KATOH Projection Through Age 28 (2014 stats): 3.3 WAR
Dan’s Grade: 50 FV

After a down 2014 campaign, Almora re-established his prospect status with a strong showing in Double-A last year. The toolsy outfielder made loads of contact, and paired it with a respectable amount of power and speed. The end result was a .272/.327/.400 triple slash, which was eons better than his .234/.250/.335 showing from his pit-stop at the same level last year. Read the rest of this entry »

Yesterday, lead prospect analyst Dan Farnsworth published his excellently in-depth prospect list for the Boston Red Sox. In this companion piece, I look at that same Boston farm system through the lens of my 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.

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. Rafael Devers, 3B (Profile)

KATOH Projection Through Age 28 (2015 stats): 9.6 WAR
KATOH Projection Through Age 28 (2014 stats): 2.3 WAR
Dan’s Grade: 55 FV

Devers destroyed two levels of Rookie Ball in 2014, which prompted the Red Sox to send him to the Sally league as an 18-year-old. He didn’t disappoint. While his numbers weren’t flashy, his power and strikeout rate were both better than the league’s average. That’s remarkable for a guy facing pitchers three or four years his senior. He could stand to walk a bit more, but that’s a minor concern considering how little walk rate tells us about players at Devers’ level. All in all, there’s a lot to be excited about with Devers.

1. Chance Sisco, C (Profile)
KATOH Projection Through Age 28 (2015 stats): 9.7 WAR
KATOH Projection Through Age 28 (2014 stats): 7.1 WAR
Dan’s Grade: 45 FV

Cisco demolished High-A pitching last year to the tune of .308/.387/.422. He ran nearly-equal strikeout and walk rates, and complimented them with modest power and a high BABIP. That performance earned him a late-season cameo at Double-A, where he also excelled in many of the same categories. A season like that would be impressive from any 20-year-old, but Cisco’s is especially encouraging since he’s a catcher. Few catchers hit as well as Cisco has, making him one of the most compelling prospects in the game.

The 2015 Rule 5 draft has come and gone. A total of 16 players were selected in the major league portion of the event. In what follows, I take a look at what KATOH has to say about the players selected. The players are listed in the order they were selected in yesterday’s draft. Projections have been produced based both on 2015 and also 2014 minor-league stats.

Tyler Goeddel, OF (Profile)
New Team: Philadelphia
Old Team: Tampa Bay
KATOH Projection Through Age 28 (2015 stats): 2.9 WAR
KATOH Projection Through Age 28 (2014 stats): 1.5 WAR

Goedel was one of the players I profiled in my Rule 5 preview. He transitioned from third base to the outfield in 2015, and he took a step forward offensively as well. He hit a strong .279/.350/.443 in Double-A and also kicked in 28 steals. Goeddel’s had some trouble making contact in the past, but his combination of power and speed is intriguing. Hitters who both possess that skill set and have already succeeded in Double-A don’t grow on trees. He may not be quite ready for the show going by the numbers, but is close enough that he probably won’t embarrass himself. And at 23, there’s still room for him to improve. The Phillies won’t be winning many games in 2016, so Goeddel is exactly the type of player on whom they should by taking fliers. Maybe they’ll catch lightning in a bottle like they did with last year’s Rule 5 pick, Odubel Herrera.

While many of you were snuggled up in your beds last night, Alex Anthopoulos and his henchmen were hard at work acquiring Troy Tulowitzki from the Rockies. You can read Dave Cameron’s piping hot take on the trade here and Kiley McDaniel’s scouting-oriented contribution on the three pitching prospects going from Toronto to Colorado here. Below, I’ll be taking a data-driven look at those same three prospects, as follow: Miguel Castro, Jeff Hoffman, and Jesus Tinoco.

Recently, I put together a calculator for my own personal use — and perhaps, eventually, the use of this site’s readers — that helps to translate (roughly) a batting prospect’s individual tool grades into wins. Lead prospect analyst Kiley McDaniel already provided something along these lines for Overall Future Value back in September by means of a chart, of which this is an excerpt:

Even for those of us unfamiliar with the parlance of scouting, this is fairly intuitive. A player who receives a 50 FV grade is regarded as an average player. An average player, in statistical terms, is one who produces roughly two wins over the course of a full season. It follows, then, that a player who receives a 50 FV is one we might reasonably expect to produce about 2.0 WAR in a season at the height of his talents. Players who receive better grades than a 50 are likely, by some order of magnitude, to produce more than 2.0 WAR; worse grades than a 50, less than 2.0 WAR.

Yesterday, Kiley McDaniel published his consummately researched and demonstrably authoritative prospect list for the champion San Francisco Giants. What follows is a different exercise than that, one much smaller in scope and designed to identify not San Francisco’s top overall prospects but rather the rookie-eligible players in the Giants system who are most ready to produce wins at the major-league level in 2015 (regardless of whether they’re likely to receive the opportunity to do so). No attempt has been made, in other words, to account for future value.

Below are the top-five prospects in the San Francisco system by projected WAR. To in this brief list, what I’ve done is to locate the Steamer 600 projections for all the prospects to whom McDaniel assessed a Future Value grade of 40 or greater. Hitters’ numbers are normalized to 550 plate appearances; starting pitchers’, to 150 innings — i.e. the playing-time thresholds at which a league-average player would produce a 2.0 WAR. Catcher projections are prorated to 415 plate appearances to account for their reduced playing time.

Note that, in many cases, defensive value has been calculated entirely by positional adjustment based on the relevant player’s minor-league defensive starts — which is to say, there has been no attempt to account for the runs a player is likely to save in the field. As a result, players with an impressive offensive profile relative to their position are sometimes perhaps overvalued — that is, in such cases where their actual defensive skills are sub-par.

t4. Clayton Blackburn, RHP (Profile)

Blackburn is projected as a reliever here. That’s not the capacity in which he’s made the vast majority of his minor-league starts, nor is it the role he’s likely to assume this year at either Double- or Triple-A. It is the role in which he made all six of his Arizona Fall League appearances, however, and that might be what’s influencing Steamer here. It matters with regard to the projection because it renders the rate stats more attractive but the overall WAR figure less so. It matters less, however, because Blackburn’s promotion to the majors isn’t imminent. In either case, he’s something slightly better than replacement level.

Over the weekend, Kiley McDaniel published his consummately researched and demonstrably authoritative prospect list for the Kansas City Royals. What follows is a different exercise than that, one much smaller in scope and designed to identify not Kansas City’s top overall prospects but rather the rookie-eligible players in the Royals system who are most ready to produce wins at the major-league level in 2015 (regardless of whether they’re likely to receive the opportunity to do so). No attempt has been made, in other words, to account for future value.

Below are the top-five prospects in the Kansas City system by projected WAR. To assemble this brief list, what I’ve done is to locate the Steamer 600 projections for all the prospects to whom McDaniel assessed a Future Value grade of 40 or greater. Hitters’ numbers are normalized to 550 plate appearances; starting pitchers’, to 150 innings — i.e. the playing-time thresholds at which a league-average player would produce a 2.0 WAR.

As a result, players with an impressive offensive profile relative to their position are sometimes perhaps overvalued — that is, in such cases where their actual defensive skills are sub-par.

5. Brian Flynn, LHP (Profile)

At points during the 2013 season, the left-handed Flynn appeared to be developing into a legitimate candidate for a major-league starting role. He produced strikeout and walk rates of 28.7% and 3.5%, respectively, over his first four starts at Double-A before earning a promotion to Triple-A, where he proceeded more or less in the same fashion, if with some of the decline in his rates that one might expect from facing more difficult competition. He hasn’t exhibited that same sort of ability in the majors yet, however. Traded to Kansas City this offseason in exchange for Aaron Crow, he has the potential to become one of the Royals’ large collection of former starters who’ve found considerable success in the bullpen.
