New Marines commandant Masato Yoshii and new Lions trainer Kazuo Matsui answered questions for the media Tuesday, while new old Hanshin manager Akinobu Okada spoke on Sunday, and I’ll give you some of those riveting exchanges.
We also had our final monthly award winners, two going to one league’s pennant winner, while the other league’s both went to its last-place team. Seven teams announced their first-round picks in Thursday’s draft, and we had the first trade of the offseason.
Some people asked where they could get the Bill James Win Shares calculations for NPB that I use to inform my award voting and which are rather different from WAR. So I’ll post the last three season’s files for you.
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.

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.

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.
