This is not only one of the final installments of Prospect Week 2018, but also Sung Min Kim’s first piece as part of his February residency at FanGraphs. Sung Min is a staff writer for River Avenue Blues, the biggest independent New York Yankees blog on the web, and has freelanced for various publications including Deadspin, Sporting News, VICE Sports, the Washington Post, and more. He can also be found on Twitter. He’ll be contributing regularly here this month. Read the work of all our residents here.

While I’ve been an ardent follower of Major League Baseball since middle school, my interest in the sport increased considerably when I began following the Asian leagues closely. There are three popular leagues in East Asia: Nippon Professional Baseball (NPB) based in Japan, Korea Baseball Organization (KBO) based in Korea, and the Chinese Professional Baseball League (CPBL) based in Taiwan. I was “born into” the KBO because of my Korean nationality. I slowly learned more about the NPB, though, as I grew up and Korean stars like Tae-Kyun Kim, Samson Lee, Seung-Yeop Lee, etc., headed there to play.

At around the time I was becoming more well acquainted with the particulars of the aforementioned leagues, major-league teams also began showing greater interest in Asian talent. Daisuke Matsuzaka‘s move to Boston was particularly significant to raising the profile of Asian baseball in the States. Yu Darvish and Masahiro Tanaka made their own splashes by bringing posting fees to their respective NPB teams and earning big contracts right out of Japan. Hyun-Jin Ryu’s move to the Dodgers was a landmark event, too, as it represented the first time ever that a Korean-born KBO player landed a big multi-year deal with a major-league club. More recently, of course, the entire Shohei Ohtani storyline — which ultimately landed the two-way star in Anaheim — has unfolded in very public fashion. There are more I’d mention but I’ll spare you for now.

It’s clear that more attention has shifted to the Asian leagues’ top players. There are clear major-league talents on the east side of the globe, and some of them — mostly the star-level types in each respective league — have decided to forego the comfort of their domestic leagues to challenge themselves in a whole new culture.

Some of those experiments have worked out, some have not. It is not easy to predict how a particular player will do in majors because there are so many factors to weigh. Skill is one thing. There are also cultural adjustments, too, and subtle differences to which players must adjust on the field. For instance, early in his MLB career, Hideki Matsui had difficulty dealing with the two-seam-heavy approach utilized by some pitchers. It is difficult to become adequate in all these aspects right away — especially for those players who are expected to start. Nonetheless, many Asian players dream of playing in the majors.

So, here, I present a list — accompanied by scouting reports — of six prospects playing in Asia. For this list, I considered only those players who (a) would be available to leave Asia within the next three years (or, before the start of the 2021 season) and who (b) have expressed interest in coming to the MLB or have, at least, not publicly refuted such a thing. Some players, like top NPB shortstop Hayato Sakamoto of the Yomiuri Giants (dubbed as the “Derek Jeter of Japan”), prefer to stay in Japan. Sakamoto has been ML scouts’ favorite for a while, but it’s possible that he just wants to stay and remain a star of Japan’s most popular team.

Yusei Kikuchi, LHP, Saitama Seibu Lions

Kikuchi is all but guaranteed to appear in the States by 2019. Not only does he features an arsenal that would easily make him a starter in the majors, but also he has strongly expressed desire to come over to the US. Back in 2009, as a top high-school pitching prospect for Hanamashi Higashi (the same high school attended by Shohei Ohtani attended), Kikuchi attracted much MLB interest. For instance, the Rangers recruited Derek Holland to try to persuade Kikuchi to sign with Texas. However, Kikuchi decided to stay in Japan and was drafted in first round by the Seibu Lions, for whom he has pitched ever since.

I’m writing this Thursday for publishing Friday, and that’s always a risk when you’re dealing with a player on the market, because you never know when circumstances might change. My topic is Jake Arrieta as a current free agent. He could, at any moment, cease to be a free agent at all. This is the chance I’m taking, but, I have to say, I like my odds. It doesn’t seem like Arrieta’s about to make a decision.

So let’s think about that for a few minutes. Arrieta is one of several Scott Boras guys out there, and he’s one of the higher-profile starters in baseball. It wasn’t long ago at all that it seemed like Arrieta might be the best starter in the sport, and even his most recent ERA was only 3.53. Arrieta’s at that point where he’s right between young-ish and old, so you’d think he’d have some years left in his arm — he’s only about five months older than fellow free agent Yu Darvish. But there hasn’t been very much Arrieta buzz. Not that those of us on the outside always get to know precisely what’s happening on the inside, but there haven’t been many Arrieta rumors. His market still hasn’t fully developed as expected.

Darvish would have something to do with that. Various trade options would have something to do with that. Yet, potentially, there’s also an additional factor. Jake Arrieta is out there, to be signed. Where are the Cubs?

Eric Longenhagen and Kiley McDaniel published their top-100 list on Monday. Other outlets have released similar lists, as well, recently — outlets including Baseball America, Baseball Prospectus, Keith Law, and MLB Pipeline. I submitted my own contribution yesterday with KATOH’s top-100 prospects. All of these lists attempt to accomplish the very same goal: both to identify and rank the best prospects. But KATOH goes about it in a very different way than the others. While most others rely heavily on scouting, KATOH focuses on statistical performance.

On the whole, there’s a good deal of agreement between KATOH and the more traditional rankings. Many of KATOH’s favorite prospects have also received praise from real-live human beings who’ve watched them play. Ronald Acuna, Vladimir Guerrero, Jr., Brent Honeywell, Michael Kopech, and Kyle Tucker all fall within this group. In general, there is a lot of agreement. However, there are other KATOH favorites who’ve received little public consideration from prospect analysts. The purpose of this article is to give these prospects a little bit of attention.

For each position, I’ve identified the player, among those excluded from all top-100 lists, who’s best acquitted by KATOH. These players have performed in the minors in a way that usually portends big-league success. Yet, for one reason or another, each has been overlooked by prospect evaluators.

Of course, the fact that these players missed every top-100 list suggests that their physical tools are probably underwhelming. That’s very important information! Often times, the outlook for players like this is much worse than their minor-league stats would lead you to believe. There’s a reason people in the industry always say “don’t scout the stat line.” Although KATOH scouts the stat line in an intuitive fashion, it still overlooks important inputs that can predict big-league success.

Still, the stat-line darlngs sometimes pan out. I performed this  exact same exercise last year, as well, and I’m proud to say there were some big successes. Rhys Hoskins, Jake Faria, Ben Gamel, Chad Green, and Brandon Nimmo have each blossomed into productive big leaguers just one year out. Zach Davies and Edwin Diaz also appeared in this space two years ago. Of course, others haven’t worked out so well. Clayton Blackburn, Dylan Cozens, Ramon Flores, and Garrett Stubbs: none of them were particularly useful major leaguers in 2017. There will be hits, and there will be misses, especially when you’re dealing with non-elite prospects.

C – Jake Rogers, Detroit (Profile)

Why KATOH Loves Him
Rogers hit a respectable .261/.350/.467 across two levels of A-ball last year, pairing an 11% walk rate with encouraging power. Most impressive of all, however, is that he did so as a catcher — a position where good hitters are few and far between. Rogers isn’t just any catcher, either: Clay Davenport’s defensive numbers graded him out as elite. Elite defensive catchers who can also hit a little are exceptionally valuable.

Why Scouts Don’t (J.J Cooper)

He has a big leg kick to start his swing, and takes a ferocious cut with a pull-heavy approach. When his swing works, he has the power to deposit pitches in the left-field bleachers. When it doesn’t, he rolls over ground outs or hits a number of harmless pop outs. Evaluators generally see Rogers as a below-average hitter with a lot of swings and misses and average bat speed.

My Thoughts
Usually, KATOH’s catcher crushes are good hitters who are questionable behind the plate. Rogers is the exact opposite, as his offense is the questionable piece. Eric Longenhagen called him “best defensive catching prospect I’ve seen, a polished receiver and cat-like ball-blocker with a plus arm” over the summer. Even if Rogers’ A-ball numbers ultimately don’t translate, he could still be a solid regular given how little catchers hit. For example, Martin Maldonado defended his way to 1.1 WAR last year in spite of a 73 wRC+.

An interesting thing happened last season in interleague play. The American League won 53% of the games. That’s not the interesting part. The AL has won the majority of interleague games for 14 years in a row. But while that was happening, the NL did take one step forward. The designated hitter is an AL thing, something that AL teams have to actually plan for. NL teams kind of just wing it. And yet NL designated hitters in 2017 out-hit AL designated hitters. Here’s a plot of league DH wOBA, going back to the start of interleague play just over two decades ago.

Over 21 years, NL designated hitters have out-hit AL designated hitters three times. Last year, the gap was 11 points of wOBA. In 2009, the gap was 16 points. And, in 2003, the gap was an incredible 31 points. Weird things happen, but, again, it shouldn’t be surprising that the AL is usually better here. Those teams invest in the DH position. Their DHs are used to the work. The NL just benefited from a little bit of randomness.

We continue Prospect Week 2018 by trying to address a question frequently asked by fans of teams that have just graduated multiple high-level prospects — namely, where would those graduated prospects rank if they were still eligible for the Top 100? We usually don’t have that answer ready off the top of our heads since, as prospect analysts, we aren’t thinking about those players very much. We decided that wasn’t okay, though. So now, whenever we do an updated top-100 or midseason list, we will also provide an update on the prospects who have lost their eligibility in the previous/current year.

The team that eventually signs Neil Walker will be getting a player who has been consistent and dynamic over the course of his career. Those descriptions come courtesy of the 32-year-old free agent himself — and they’re pretty accurate. In his eight full big-league seasons, Walker has averaged 2.7 WAR annually, with the ebbs and flows remaining within a reasonably narrow range. Ditto his OPS, which has always been higher than league average, but never north of .823.

A first-round pick by his hometown (give or take a few miles) Pirates in 2004, Walker was Pittsburgh property prior to being traded to the Mets in December 2015, and then to the Brewers last August. Along the way, he’s remained steady-as-she-goes productive, as well as a positive influence in the clubhouse.

“I’ve been able to fit into many roles with the teams I’ve been on,” Walker told me at the tail end of last season. “I’ve hit at the top of the order and the middle of the order. I’ve been a run producer and a run scorer. I’ve played pretty decent defense. I feel I’ve been a fairly dynamic and consistent player.”

Baseball is in an era of extremes. While the game has always evolved, it’s rarely — if ever — evolved so quickly.

Home runs have increased dramatically due to a variety of factors, velocity continues to rise, bullpens keep on gaining a greater share of the overall workload. The MLBPA, meanwhile, has been taken aback by the changing complexion of the free-agent marketplace, defined this offseason by stagnation — in part due to the speed with which organizations have adapted to the terms of the latest CBA.

Another labor-ownership issue — pace — continues to be problematic. Not necessary the overall time of games, but the increasing duration of seconds between pitches in an age when attention spans are continually tested. To really engage a fan and customer, particularly the next generation, you probably don’t want them to be able/compelled to look at their smartphone between every pitch.

There’s a lot of extremes. And I’m writing to discuss yet another here today: the disabled list.

Below is KATOH’s 2018 top-100 prospect list. If you’re a regular FanGraphs reader, you likely know the drill by now. But in case you need a refresher, KATOH produces a WAR forecast for a player’s first six major-league seasons. It incorporates age, offensive performance, defensive performance, and other characteristics from the past two seasons. There are certainly drawbacks to scouting the stat line, but due to their objectivity, the projections can be useful in identifying prospects who might be overlooked or overrated.

I have made a few updates this time around. KATOH now features:

1. The batted-ball data (for both hitters and pitchers) available on our awesome leaderboards. Among other things, this helps KATOH differentiate between fluky and un-fluky high- and low-BABIP hitters.
2. A greater reliance on recent data for the construction of the model and less dependence on data points from 10-plus years ago.
3. Numbers from the Dominican Summer League, which was previously outside of KATOH’s scope

Astute readers might notice that this article does not include a top-100 for KATOH+, the version of KATOH that incorporates scouting grades in addition to the stats. Since Kiley and Eric are still working their way through the organizational lists, I don’t have up-to-date FV grades for every prospect. Rather than plugging in FV grades from a year ago (or more), I am holding off on KATOH+ for now.

Episode 800
In her most recent and also first appearance on FanGraphs Audio, guest Meg Rowley revealed that she’d done some scholarly work in the area of political representation before turning to the more important matter of baseball weblogging. Here, she wonders whether a former major-league player is as well suited to deal with ownership’s relentless negotiators than a labor lawyer.
