The NPB announced that they signed Takuya Mizuguchi (20) to an Ikusei Umpire contract. Mizuguchi completed the NPB Umpire School last year and was assigned to the Shikoku Island League this year, where he won the Top Umpire Award.
Former Independent League players will no longer count against the Japan Amateur Baseball Association's (JABA) three former professional players per team cap. Under previous rules, former Independent League players were included in the count. Additionally, one-year restriction periods will be dropped for former Independent League players from either the BC League or Shikoku Island League.
