NPB’s balls were different in 2024

I’ve been going on all year about the ball all year, about how it wasn’t flying as well as it did in previous years. At the Japan Series, former pitcher Hiromi Makihara was surprised to find that someone outside the loop would know that there was a problem. I told him it was simple arithmetic, when home runs drop by 35 Percent, it’s no secret. He was rightly impressed.

Having heard from a member of one club’s analytics staff that the yarn used to stitch the covers on the balls was fraying on hard contact, I assumed the issue was yarn from a new supplier that was not up to spec. But Makihara revealed at the Japan Series that the problem was related to a change in the manufacturing process after Mizuno moved its production of NPB balls in the summer of 2023 from China to Taiwan, which a senior NPB official confirmed.

Your Hall of Fame ballot

While I cannot open the voting for the Japanese Baseball Hall of Fame players division ballot to the public, I am curious what you all think.

I would like all readers who haven’t already voted on Twitter or other social media platforms, to submit their seven votes in the comments so I can compile them and announce the readers’ choices. So please, each of you, name your magnificent seven…

Below are the candidates, and how they compare to existing players in the Hall of Fame in terms of Bill James’ Win Shares.

The three tables for position players, starting pitchers and relievers give their career win share totals, including a slight adjustment for win shares accumulated in MLB, the average of each player’s three most-valuable seasons, and the average win share value of each player’s best five-year span.

I’ve listed them separately, because win shares doesn’t seek to make the best pitchers equal to the best position players. For that reason, I compare the starting pitchers to existing hall of fame starting pitchers, and relievers to the trio of specialty relievers who are now enshrined in the museum’s long narrow hall.

3 starting pitcher candidates

The “starting pitcher” averages are a little misleading because until the mid 1970s, there were three kinds of pitchers, top starters who also came on to relieve in high-leverage situations, starters who switched back and forth between starting and relieving, and a few pitchers who rarely started. The averages also do not include the quality pitchers who converted to other positions after their arms gave out. Their careers are averaged with the position players.

3 relief pitcher candidates

There are only three dedicated relief pitchers in the Hall of Fame, Kazuhiro Sasaki, who is head and shoulders above Shingo Takatsu, and Tsunemi Tsuda, who was as good as Takatsu, but whose career and life were cut short by cancer.
