Over the course of the last year, I’ve published projections for a boatload of prospects at this site. Now that the 2017 regular season is complete, I thought it might make sense to review how KATOH has performed with specific players. Last week, I looked at some instances where KATOH’s forecasts looked prescient. For this particular post, I’d like to look at some instances where KATOH’s forecasts have looked foolish.

Allow me to point out immediately that none of this is conclusive: we’re only a year (or less) into the big-league careers of the players included here. Labeling a six-year projection as definitively “right” or “wrong” following a single season is obviously premature. That said, we undoubtedly have a much clearer picture of these players’ futures than we did six months ago.

This analysis compares each player’s industry-wide consensus to his stats-only KATOH projection — which does not consider a player’s ranking on prospect lists. Stats-only is KATOH’s purest form and also the version that disagrees most fervently with the establishment. Note that I did not consider cases where all parties were wrong, such as Aaron Judge. Although KATOH’s No. 53 ranking of Judge looks silly now, it was on par with other rankings, which ranged from 44th to 145th.

Picking players for this article was obviously somewhat subjective. So if you have a player in mind that I neglected to mention, feel free to complain about it in the comments!

Prospects KATOH Liked
Here are the players on whom KATOH has typically been more bullish than other outlets. Players are listed in general order of “failure” in 2017.

Dylan Cozens, OF, Philadelphia

Last winter, KATOH ranked Cozens as the top prospect in baseball. The large outfielder proceeded to tarnish my reputation by hitting .210/.301/.418 with a 36% strikeout rate in Triple-A this year. There was a lot to like about Cozens’ 2016: he mashed 40 homers, stole 21 bases, and graded out well in right field — all as a 22-year-old at Double-A. But evaluators were concerned about his strikeouts and predicted his power numbers would crater outside of Reading. The book is far from closed on Cozens, who KATOH still sees him as a back-end top-100 guy. But tippy-top prospects don’t have seasons like Cozens’ 2017.

Writing this article was a lot of fun. Like everyone else, I enjoy saying “I told you so” when I’m right. But I also acknowledge that I’m often wrong. So as much as I’d like to tout these cherry-picked success stories and move on to current projections, I feel I’d be doing you a disservice if I didn’t write another article pointing out KATOH’s misses. Stay tuned.

Here are the players on whom KATOH has typically been more bullish than other outlets. Players are listed in general order of “success” in 2017.

Rhys Hoskins, 1B/OF, Philadelphia

As you’re probably aware, Hoskins had a pretty good summer. But before he was hitting homers at a ridiculous clip, Hoskins was an unheralded first-base prospect who had never cracked a major publication’s top-100 list. KATOH was all over him, though, due to his impressive minor-league numbers. My system ranked him No. 54 in the preseason and No. 14 when he was called up. He also cracked the All-KATOH Team in the preseason. The best minor-league hitters often succeed in the majors as well. As obvious as that sounds, the case of Rhys Hoskins shows that we sometimes overthink these things.

With September call-up season upon us, the Phillies have summoned top prospect J.P. Crawford from the minor leagues. He made his debut last night, starting at third base and notching his first career hit. Prior to his call up, Crawford hit .243/.351/.405 in Triple-A this year, including a powerful .284/.385/.517 since July 8th.

Crawford is an extremely talented player who can provide value in more ways than one. His minor-league batting lines don’t necessarily jump off the page, but in the context of his age and defensive value, they’re rather impressive. That’s why he’s been appearing near the tops of prospect lists — including KATOH’s — for years. Baseball America ranked him among the top-14 prospects each of the last three seasons, while Baseball Prospectus ranked him No. 4 each of the last two. Eric Longenhagen ranked him No. 9 in the preseason and No. 34 in his summer list.

In the table below, you’ll find a treasure trove of information pertaining to the prospects who changed hands this trade deadline. There were 67 of them in all. Since there was a flurry of early trade activity this year, I’m using a liberal definition of “trade deadline” that considers all trades since the July 13th Jose Quintana deal. For reference, I performed a similar exercise last year. Read the rest of this entry »

The Dodgers traded for Yu Darvish. Below are the projections for the prospects the Rangers received in exchange for Darvish’s services. WAR figures account for the player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.

Willie Calhoun, 2B/LF/DH (Profile)

KATOH: 9.4 WAR (15th)

KATOH+: 8.9 WAR (24th)

Calhoun has hit a rock-solid .298/.357/.574 at Triple-A this season as a 22-year-old second baseman. His power numbers have been undoubtedly helped by the PCL and he doesn’t exactly look like a premium athlete. But still: Calhoun’s blend of contact and power makes him extremely exciting. His defense, however, is suspect. Clay Davenport’s metrics say his defense at second has improved this year, but going from unbelievably bad to merely really bad doesn’t do much to help Calhoun’s case. Calhoun is a prospect without a position for now, so a move to the American League makes a ton of sense. KATOH had Calhoun as the Dodgers’ second-best prospect, behind Alex Verdugo.

The Yankees traded for Sonny Gray. Below are the projections for the prospects the Athletics received in exchange for Gray’s services. Although he is a major part of this trade, I do not have a projection for James Kaprielian, who has thrown just 29 innings as a professional and zero since April 2016. WAR figures account for the player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.

KATOH: 9.0 WAR (28th)

KATOH+: 8.8 WAR (18th)

Three minor-ish trades went down on Friday night. The Mets acquired A.J. Ramos from the Marlins for Merandy Gonzalez and Ricardo Cespedes; the Nationals acquired Howie Kendrick from the Phillies for McKenzie Mills; the Orioles acquired Jeremy Hellickson from the Phillies for Garrett Cleavinger and Hyun Soo Kim.  Below are the projections for the prospects who changed hands. WAR figures account for the player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.

None of the players dealt last night are top prospects, and as a result, their likelihood of outcomes graphs are heavily skewed towards “no MLB”. Kyle Glaser recently found that fewer than one in five prospects traded at the deadline contribute more than one positive WAR season. All three of these pitchers seem like good bets to fall into that bottom four-fifths.

With the trade deadline swiftly approaching, it’s time for some updated KATOH rankings. I know you’re not here to read about assumptions and caveats, so I’ll keep the non-list part of this article short and sweet.

• For each player, KATOH produces a WAR forecast for his first six years in the major leagues. There are drawbacks to scouting the stat line, but due to their objective nature, the projections here can be useful in identifying prospects who might be overlooked or overrated.
• KATOH+ incorporates Baseball America’s midseason top-100 list and Eric Longenhagen’s preseason FV grades for players excluded from BA’s list. Stats-only KATOH does not consider prospect rankings.
• These projections account only for minor-league stats. While I’ve done work with college players, I have not yet attempted to merge college and minor-league data. These projections also do not account for any major-league performance.
• All players with at least 200 minor-league plate appearances or batters faced in 2016 and/or 2017 were considered.
• This isn’t “Chris Mitchell’s Top 100 List,” and certainly not “FanGraphs’ Top 100 List.” This is simply the output from my far-from-perfect statistical model.

Thoughtless and bad editor Carson Cistulli overlooked this post when Chris Mitchell submitted it on Friday afternoon. That’s the reason it’s appearing on Tuesday.

The Mariners and Cardinals completed one-to-one swap of outfielder Tyler O’Neill and lefty Marco Gonzales on Friday. As Dave Cameron has pointed out, this represented a case of the Mariners trading away future upside for some much-needed, immediate rotation depth. A move of that type is understandable given the state of the Mariners’ rotation and their position in the Wild Card race, but KATOH thinks the gap in value between these two prospects is quite large.

Below are the projections for the three players whom the White Sox receive. WAR figures account for the player’s first six major-league seasons. KATOH denotes the stats-only version of the projection system, while KATOH+ denotes the methodology that includes a player’s prospect rankings.

Tyler O’Neill, OF (Profile)

KATOH: 7.1 WAR (34th overall)
KATOH+: 6.0 WAR (52nd overall)

O’Neill elevated his prospect stock last season, when he slashed .293/.374/.508 at the Double-A level. But he’s had a tougher time at Triple-A this season, hitting only .244/.328/.479. Part of that, however, has to do with playing in a park that’s tough on right-handed hitters. Eric Longenhagen gave him a 50 FV over the winter and listed him as an honorable mention on his top-100 list.

O’Neil is a three-true-outcomes prospect who’s homered, walked, or struck out in over 43% of his trips to the plate this year. His power is his biggest strength, as he’s belted a remarkable 75 homers since the start of the 2015 season while also kicking in 76 doubles and triples. But all that power comes with a lot of strikeouts, as evidenced by his 27% strikeout rate this year.

After they shipped Todd Frazier to the Yankees in exchange for prospects earlier this week, the White Sox replaced him on their roster with Yoan Moncada. Moncada was hitting a healthy .282/.377/.447 at Triple-A, highlighted by his 12 homers and 17 steals. He hits for average, hits for power, steals bases, and even draws walks. Very few players can hit like Moncada does while also providing value in the field and on the bases. That’s why he was a fixture at the top of midseason prospect lists this summer. Baseball America and Baseball Prospectus both ranked him No. 1, while Keith Law put him at No. 13.

But for all his strengths, Moncada has some weaknesses that we shouldn’t overlook. Most notably, he strikes out a bunch. Moncada’s struck out in over 28% of his trips to the plate this year. Though it’s been somewhat hidden by his high batting averages, Moncada has had a lot of trouble making contact against minor-league pitchers. This suggests he’ll have even more trouble doing so in the big leagues, which is exactly what happened in Boston last September when he struck out 12 times in 20 plate appearances.

There’s also the matter of Moncada’s defense. He’s primarily played second base since emigrating from Cuba, and the prognosis for minor-league second basemen isn’t great. The fact that he’s already been deemed “not a shortstop” is a knock against him in KATOH’s eyes. Furthermore, his defensive metrics at second base aren’t great. He’s been right around average there by Clay Davenport’s fielding data this year and was several ticks worse than average last year. This suggests he may not be a defensive asset in the infield.
