[1/27/2015] Mizuno to continue manufacturing NPB baseball

The NPB held an "open competition" to find their next baseball manufacturing partner. The media learned earlier today that the league will renew their contract with Mizuno, citing quality, supply capability, and price as reasons for their decision.

The competition began with four suppliers providing the NPB with sample baseballs. The balls where handed out to the twelve NPB teams for testing during the fall camp. A survey helped narrow the field to two companies. After additional discussions the league decided to go with Mizuno.

The NPB is expected to sign a formal agreement after details have been fleshed out.

[7/18/2014] JPBPA to request a coefficient of restitution target value, instead of upper and lower limits

by on Jul.18, 2014 @ 11:48 pm, under NPB
Tags:

The Japan Professional Baseball Players Association (JPBPA) held a meeting in Tokyo today.  Among issues discussed:

  • submitting a request to replace the upper and lower coefficient of restitution limits with a single target value to shoot for.  The NPB and the twelve teams will most likely approve the request and implement changes to the rules for the 2015 season.
  • requesting a time limit extension for players that are deciding whether or not to accept or decline a cut in salary that goes over the limits.
  • asking for an increase in the number of games Western League teams play.
  • increasing the number of opportunities active professional players have to interact with high school players by working with the Japan High School Baseball Federation.
