I'm still not convinced that this is much more than the media trying to explain the uniqueness of Japanese baseball (as fed through a gullible US media). Something similar to the "Gyroball" phenom.
Michael Westbay and Jim Allen in their Japanese Baseball Blog notes the following:
".....The balls are not that much differant and in the balls used in Japan, they can vary enough to make that differance unrecognizable.
There was recently an article in both Nikkan Sports and Shukan Baseball which tried to find why balls are flying out at such a high rate. There's a lot of jargon that I didn't understand, and need to take some time to learn before I can translate the articles with a reasonable amount of confidence. But my first impression is that the balls are being manufactured to the same specs as they have been in previous years, and with the same hanpatsu keisuu (repulsion coefficient).
I did translate the specs for balls and how they're put together at an unnamed Mizuno factory in a SABR mailing list recently. This was taken from the 2004 #25 issue of Shukan Baseball:
Spec
The ball must be made of cork, cow hide, and other materials.
The ball must be between 141.7 and 148.8 grams.
The ball must be between 22.9 to 23.5 cm in circumference.
...."
Another poster on the same site (who I agree with) says they are essentially the same:
".....The ball is the same size.
Weight L Weight H Circumference L Circumfrence H
MLB 5 oz 5.25 oz 9 in 9.25 in
NPB 5.002 oz 5.253 oz 9 in 9.29 in...."
But what might be construed as a differance is that if you take a ball at minimum size or weight specs from one league and compare it with a ball at maximum size or weight, than Walla! You will have a differant ball.
Also, interesting is the fact that I believe the home team will choose the balls for the game here in Japan.
Most pitchers choose a ball from its feel with the seams and surface depending on the type of pitches that they throw. They normally will not notice a gram or two differance in the weight.
I had a conversation with a certain pitcher who threw in the states and has since returned to Japan. He said he noticed no difference in the ball. I reminded him of an interview he did with the J-media that was widely televised where they asked him if there was difference in the ball and he said that there was a definate difference. He told me that this was what the reporters had told him to respond with when the asked the question. I asked him why he didn't say there wasn't and he said the media was emphasizing that point for the interview and he didn't want to get on their wrong side since media coverage is so important to Pro athletes.
Whadda ya think Capt'n? Another Gyro-ball again?
