The new kids

There has been a lot of buzz about Hanshin Tigers newcomer 22-year-old infielder Teruaki Sato, the club’s powerfully built first pick last autumn. I’m not totally immune to the spring chatter, but he’s big fast and strong and making an impact. On this week’s TBS news program “Sunday Morning” Isao Harimoto said he keeps his weight too far back and is going to struggle once pitchers are throwing for real during the season.

Teruaki Sato

Most of the other talk has been about the Giants’ fifth draft pick, a high schooler named Yuto Akihiro. Akihiro, recently promoted to the first-team camp, is 2 meters tall, the tallest Japanese pro baseball player since pro wrestler Giant Baba pitched for the Giants in 1955, and also gives the Giants two players whose family names are common first names, the other being Shinnosuke Shigenobu.

Akihiro is ridiculously short to the ball for such a big guy, and he’s been making mince-meat of spring training pitching, but as a no-name low draft pick straight out of high school, does he have a tougher hill to climb than other players similarly situated?

I asked that question because of something a colleague once told me.

Yuto Akihiro

Giants, draft order and status

Ten years ago or so I interviewed Itaru Hashimoto, an up-and-coming Giants outfielder, whom my Yomiuri Shimbun colleague identified as a rarity, a low-round pick who turned pro out of high school who had a chance to earn a regular job. Hashimoto was the Giants’ fourth-round draft pick.

But is that really a thing?

If the Giants’ do have a bias against low-round picks out of high schools they should have lower career values than their low-round picks who turned pro after high school and lower values than those from other NPB teams.

I dug into my draft data base to look for the career win share totals of players drafted out of high school in the fourth round or higher, then grouped those based on whether they were signed by the Giants or other NPB teams. Using Bill James’ Win Shares as a measure of value with three win shares equaling one team.

Avg career win shares of H.S. draftees before 2010

The Giants’ lower picks out of high school have definitely been less valuable than those of other teams at every step. Of the 73 Giants in the survey, 13 had 10-plus win shares or 18 percent of the total with an average career value of 8.8 win shares.

Of the 684 non-Giants, 146 produced 10-plus career win shares, or 21 percent, not a great deal better than the Giants, but their average career value was 15.8, nearly twice as high.

So, compared to the rest of NPB’s low-round picks out of high school as a whole, it’s accurate to say the Giants are quite a bit worse at turning those picks into productive players.

Avg career win shares of non-H.S. draftees before 2010

But if the Giants’ issue is an organizational bias against high school players, then we would expect their non-high school players to be more like the NPB norm.

Prior to 2010, the other 11 NPB teams signed 710 players who weren’t coming out of high school in the fourth round or lower. These players had an average career value of 17.6 win shares, while 233 or 33 percent produced 10 or more win shares.

The similar group of 70 players signed by the Giants produced an average of 11.6 career win shares, while 27 percent had 10 or more career win shares.

It seems that while the Giants are worse at turning their high school draft picks into productive players, their guys who turned pro after high school have not done a whole lot better, but are a little closer to the NPB norms.

But while the Giants may have had an organizational bias against low-round high school picks, their real bias is more against lower-round picks, period. The table below shows the players taken, not by rounds, since the top rounds of Japanese drafts are really a jumble of different meanings, but I’ve ranked the draft picks, and split the top 36 players signed in each draft.

The picks of the litter

As the table below shows, the Giants have had a huge advantage over the rest of NPB in the results of their new guys taken in the first tier of the draft, and that is the ONLY advantage they have in the draft over their rivals.

The development gap

The shape of talent

One cause that was suggested for the gap was that CL teams look for players with more polished skills while PL clubs are more likely to go with players who have higher physical potential.

On Twitter, Brian Cartwright suggested it was a correctable issue if CL teams did a better job of evaluating and developing their talent. If that is the case, a study of value from the draft would reveal a talent gap leaning toward the PL, and it does.

In my story on the Hawks’ odds of winning this year’s Japan Series, I made a conservative estimate that the six PL teams would combine for a .530 winning percentage if thrown into a balanced schedule among all 12 teams.

“We don’t know how much better the Pacific League is than the Central League, but over the history of interleague play, the PL teams have a .532 winning percentage. Over the previous five seasons, the PL winning percentage was .555, and the PL’s Pythagorean winning percentage is .559.”

Jim’s Series odds

A note about using win shares

I’m going to measure individual player output using Bill James’ Win Shares. This system gives each team 3 win shares for a win. These are then divided between the offense, fielding and pitching. Those are assigned to individual teammates based on individual performance.

This method has pros and cons, but since a league’s win share total can’t exceed 3 times its total wins, one league outperforming another doesn’t show up in win shares except in interleague. The two leagues each played 120 games in 2020 with no interleague, and had the same number of wins (counting ties as two halves of a win), so even though the PL is evidently stronger, win shares won’t reveal it. What it does reveal is the relative shape of the talent in the two leagues.

And from a glance at the careers of players signed since NPB adopted its draft, it’s clear that the PL teams are now Japan’s draft kings.

Drafting and development

The draft began in 1965, and including undrafted amateur free agents, the career value of domestic players signed by CL teams was more than that of players signed by PL teams over the first 28 years. Over the last 28 years, that trend has reversed.

So while the two leagues have essentially equal access to domestic talent, domestic talent has become become a larger share of the PL’s overall talent base.

2007 – 20184,2224,9971.18
Value expressed in career value as calculated using Bill James’ Win Shares, and includes MLB WS

I did not know this trend existed at all. Did you? It should have been obvious, I suppose. From 1966 to 1979, the CL went 12-4 in the Japan Series. From 1980 to 2007, the two leagues split the Series 14-14. Since then the PL has lead 11-2.

Do CL clubs appease Giants in draft?

Another issue people in the game for a long time mentioned is the custom of CL teams sometimes shying away from competing with the Giants for amateur talent.

This latter assumption, if true, doesn’t appear to be a big deal now, although that may have more to do with teams not being able to sign top corporate and college players before the draft — something that had been in play from 1993 to 2006.

Although the Giants have the most value in Japan from their No. 1 picks since 2000, and the most total value from their picks 1-5 than any other CL team, this latter edge is not huge. The Tigers, BayStars and Swallows have all done nearly as well.

But looking at the overall amount of domestic talent taken from the draft, the PL has compiled a huge advantage. Using Bill James’ Win Shares, players signed out of the draft from 2000 to 2018 by PL teams have produced 9,046 win shares, or 3,015 wins — some of those are with other teams including some in MLB. Players signed by CL teams out of the draft during the same period, have produced 8,315 WS, or 2,770 wins.

Skeletons in the closet

NPB entered the 2007 season under a cloud when the guy assigned by the Seibu Lions’ parent company to take over the team decided to be of service to baseball by having a look into the team’s player acquisition closet and sweeping out the skeletons.

The boss assigned a third-party investigation to the task and found a long history of abuses of the system by Seibu and other clubs. Instead of being celebrated for creating an atmosphere of transparency, Seibu was punished for bringing the game’s disrepute into the light.

However, that also ended the systems where pro teams could agree to sign up to two corporate or college stars before the draft at the cost of reducing their access to high school talent, making the draft more of a crapshoot.

The Seibu Lions’ crusade for transparency cost them in 2007, when they were barred from the first two rounds of the high school draft. But embarrassing NPB and forcing it to eliminate the old draft system has done nothing to slow the PL’s dramatic improvement in drafting and developing domestic talent.

Free agency

Free agency started in Japan after the 1993 season, but until 2005, it was essentially one-way traffic. Atsunori Inaba changed that.

He left the Yakult Swallows ostensibly for MLB, but signed with the Nippon Ham Fighters in 2006 after failing to get a guaranteed contract overseas. Prior to Inaba, the total value from CL players moving to the PL was 12 win shares. Going the other way, players produced 190 for CL teams after leaving the PL via free agency.

Inaba had an MVP-caliber season for the Fighters in 2006, and after that year, the free agent scoreboard stood at 196-35 in favor of the CL. Things really began changing in 2011, when Seiichi Uchikawa, left the BayStars for the SoftBank Hawks.

Since 2006 the score is 477-436, but that’s even counting two players in the PL column who high-tailed it back to the PL after spending a brief time with the Giants, Hiroki Kokubo and Saburo Omura.

Import export business

Leaving on a jet plane

After the 1994 season, Hideo Nomo dropped the PL’s Kintetsu Buffaloes like a bad habit. His move began to put another dent in the PL’s growing talent surplus.

Players who left PL teams to play in the majors have produced 1,112 major league win shares from 1995 to 2019. The CL graduates produced 791 win shares in the big leagues during that time. The top of the list is Ichiro Suzuki at 324, followed by Hideki Matsui (150) and Nomo (123).

Three former CL players are next in line — Hiroki Kuroda (81), Norichika Aoki (78) and Koji Uehara (76) but it hasn’t been updated for 2020, when Yu Darvish pulled even with Kuroda. Masahiro Tanaka (69) will pass those three former CL guys if he has three more productive seasons.

Foreign trade

Because of the nature of win shares, the value of a league’s important talent is essentially the flip side of domestic talent within that league. Thus, if the win shares attributed to domestic players increases in a league, the number of win shares that go to imports must decrease. That give us table below.

The same would be true if a bunch of extremely talented left-handed hitters suddenly peaked at the same time in a league. The right-handed hitters wouldn’t get worse, but as a group, they would create a smaller share of the league’s wins.

I suspect that the imported talent base in the PL is actually quite stable, and that the gap is not nearly as large now as it looks.

Move it on over

A parallel to the movement of free agent talent is the value of imported players in the league other than the one they first signed in. Since 2008, the Pacific League, long a supplier of imported talent to the Central League, has had a cumulative trade surplus since 2008.

WS values from imported players


The big difference between the two leagues right now is, as my Twitter follower suggested, simply a matter of talent evaluation and development, that has seen PL teams do a better job of drafting and developing domestic amateurs than the CL.

This appears to have been going on for some time, but for a long time was counterbalanced by what used to be a large drain of free agent talent from the PL to the CL, and by the PL’s losing more talent to the major leagues.

The PL for as long as I remember has been the more innovative league, and is has long been aware of the need to replace the talent lost to the CL and MLB. As mentioned in the previous article, the PL has taken more strides toward making baseball pay in Japan. And as the PL teams get better at both managing their businesses and organizing their talent, then it is going to be a tough slog for the CL to catch up.

Another look at pitchers

Since I’m on a Hall of Fame jag, I want to dig deeper into the subject of pitchers, who gets in and who gets out. I only included one pitcher, Masahiro Yamamoto, on my 2021 ballot, and perhaps I should more carefully examine the credentials of a few other pitchers on the ballot.

In the first run-through, I looked to see how often pitchers were elected into the Hall of Fame based on their MVP, Sawamura, and Best Nine Awards, and also on three measures using Bill James’ Win Shares: career value, the average value of their five best seasons, and the average value of their three best seasons.

Next year’s big new names will be two pitchers whose quality went largely overlooked because they played for weak offensive teams in hitters’ parks, Hiroki Kuroda and Daisuke Miura. But while I’m at it I’ll try and right a wrong and have a look at the pitchers I passed over in my 2021 ballot.

For a slightly different look, I’m doing pitcher Hall of Fame points that I’m going to call “career highlight points” because unlike Win Shares, anyone can count them. These are as follows:

  • MVP award: 3 points
  • Sawamura Award: 2 points
  • Leading the league in wins: 2 points
  • Leading the league in saves: 2 points
  • Best Nine award: 2 points
  • Key pitcher on a championship team (40+ games or 100+ IP): 2 points
  • Each 100 career wins: 5 points
  • Each 40 career saves: 1 point

So far, each of the 18 eligible pitchers with 21-plus career highlight points is in the Hall of Fame with the exception of the scandal-hit Yutaka Enatsu. Eight of the 12 players from 17 to 21 are in. Below 16 and it’s fuzzy.

Here are the breakdowns for the Win Shares measures:

  • Career WS above 233: 20 out of 21 in Hall
  • Best 5-year stretch average above 24 WS: 12 out of 13 in Hall. Essentially an old-timers category since the last pitcher in that group retired in 1988.
  • Best 3 season average above 29 WS: 12 out of 13 in Hall (see above).

Hiroki Kuroda

  • Highlight points: 10 – 58th
  • Career Win Shares: 244 – 13th
  • Avg WS Best 5-year stretch: 17.1 – 54th
  • Avg Best 3 seasons: 21 – 59th

As an exercise, let’s start with Kuroda.

Because of his career win shares value, the former Carp ace seems like a shoo-in, but his peak value is not as great as some of his contemporaries, and he lacks the eye-catching things like playing for multiple championship teams and winning MVP awards and so has just 10 career highlight points

Kuroda’s Wins Shares profile is similar to recent experts’ division selection, Taiyo Whales ace Masaji Hiramatsu and his contemporary, Yakult Swallows ace Hiromu Matsuoka, who has struggled on the experts’ ballot. The obvious difference? Hiramatsu had a famous pitch, his “kamisori” (razor) shoot, had two big seasons and 21 career highlight points while Matsuoka has just nine. Hiramatsu was not a lot better but LOOKED a lot better, and now he’s in.

In Kuroda’s favor, the Hall of Fame voting system is different from when those two retired in the mid-1980s, and he was both popular and a durable, successful major leaguer. My guess is he won’t have to wait for the experts’ division ballot to get in. Matsuoka’s “fault” was to be consistently good for a long time without having at least one more big year when everyone was talking about how great he was.

Here’s how the the players on the ballot this year and next year compare:

NameLast seasonHighlight PtsCareer WSBest 5-year stretchBest 3 seasons
Hiroki Kuroda20161024417.121.0
Masahiro Yamamoto20152622613.718.8
Daisuke Miura2016721115.118.6
Masumi Kuwata20071719119.624.2
Shinji Sasaoka20071517214.418.9

Shingo Takatsu20101612010.114.0
Takashi Saito2015919214.720.6

Again, this is not about who I want to see in the Hall of Fame, but rather an effort to answer the question “Who does the Hall of Fame think belongs?”

By the established standards, Hiroki Kuroda, Masahiro Yamamoto and Fumiya Nishiguchi are all Hall of Famers, and Kenshin Kawakami and Masumi Kuwata are likely to get in at some point.

Win Shares sees Miura as being better than Nishiguchi and way better than Kawakami, but he lacks the career highlights that will likely make their resumes sing to the voters. As it is Miura is probably going to fall about one good, not great, season short of getting in on career value.

You decide

Here is a table of every pitcher who is eligible to be in the Hall of Fame, and is not currently on the players’ division ballot who has a career Win Share total as high as the lowest of any pitcher in the HOF, former Carp closer Tsunemi Tsuda. An “E” in the HOF column indicates they are currently on the experts’ division ballot. HOF indicates an original member, and a year indicates when they were inducted.

I would like to say who has a chance to get on a ballot again and who is out of chances, but that’s a huge project, and anyone who is in uniform again as a coach or manager has a chance to get back on the experts’ ballot.

Maru goes behind fielding numbers

I wasn’t the only one to take note of Yoshihiro Maru’s declining fielding metrics since 2016 with the Hiroshima Carp, but I may have been the most outspoken about them. The important thing to remember, however, is that they are measures of things. And those things only become place holders for skill and ability in our heads and don’t represent actual reality.

It’s important to remember that just because someone’s metrics have declined, things other than declining individual performance might be at the root.

The table below gives three metrics for each year: Fielding Win Shares, and his ARM and UZR 1200 ratings from Delta Graphs. While Maru’s skills may have not altered one bit, his numbers rebounded in 2019 after he moved to the Yomiuri Giants.

Maru’s fielding figures


Maru’s story

“I don’t think my speed or the quality of my jumps improved any from when I was in Hiroshima. The difference was (Carp right fielder) Seiya Suzuki,” Maru said Sunday.

“As long as I’ve played, I’ve always gone to catch balls if there was ever any doubt. It wasn’t the case that I let Suzuki catch balls in the gap, but rather his being fast and getting to more balls first.”

“I think the reason my data in Hiroshima gradually shrank, was that Suzuki played more and got better.”

In 2018, Maru’s numbers took two hits, one from playing time when he missed 10 games, and another from having a good fielder in left, Takayoshi Noma, instead of the previous platoon combination of slow sluggers Brad Eldred and Ryuhei Matsuyama.

The Giants, on the other hand, put him in an outfield that frequently had Alex Guerrero (slow) in left and Yoshiyuki Kamei (old) in right, and voila! Maru’s best defensive win share season of his career.

Not my thing

One thing that took me by surprise was Maru’s opting for domestic free agency after the 2018 season instead of sticking with the Carp until he could go overseas under his own power. I always saw him as a similar player to South Korean star Choo Shin Soo.

“No that was never going to be my thing,” Maru said. “I just didn’t see myself doing that and had no interest.”

Akiyama looking to majors

Seibu Lions center fielder Shogo Akiyama revealed Tuesday that he has informed the Pacific League club he will file for free agency in order to seek a deal with a major league team.

My analysis of Akiyama’s game is HERE. You can find the Kyodo News story published in the Japan Times HERE.

Since I have completed win shares calculations for 2019. Here are Akiyama’s career figures. For those unfamiliar with win shares, three win shares are worth one win.
