Nippon Professional Baseball rosters

A Nippon Professional Baseball team's roster is the group of players who are, by the NPB Agreement, allowed to play in Nippon Professional Baseball's top-fight leagues, the Central League and the Pacific League (NPB Agreement, Article 81). This list is created from each team's list of players under control (Article 52), and players can be registered to the roster arbitrarily and at any time during the season (Article 85).
