Pacific League
The Pacific League (パシフィック・リーグ, Pashifikku Rīgu) or Pa League (パリーグ, Pa Rīgu) is one of the two professional baseball leagues constituting Nippon Professional Baseball in Japan. The winner of the league championship competes against the winner in the Central League for the annual Japan Series. It currently consists of six teams from around Japan.
History
The circuit was founded as the Taiheiyo Baseball Union in 1949 (the name changing to its current form in 1980). Daiei Stars owner Masaichi Nagata was the first president of the Pacific League.
The league began with seven teams: four holdovers from the previous iteration, the Japanese Baseball League — the Hankyu Braves, the Nankai Hawks, the Daiei Stars, and the Tokyu Flyers — and three new teams — the Kintetsu Pearls, the Mainichi Orions, and the Nishitetsu Clippers.
In 1954 an eighth Pacific League team was founded, the Takahashi Unions, to increase the number of teams to eight. Although the team was stocked with players from the other Pacific League teams, the Unions struggled from the outset and finished in the second division every season. In 1957, the Unions were merged with the Daiei Stars to form the Daiei Unions (and again bringing the number of Pacific League teams down to seven). The Unions existed for a single season, finishing in last place, 43-1/2 games out of first. In 1958, the Unions merged with the Mainichi Orions to form the Daimai Orions. This enabled the Pacific League to shrink from the ungainly seven-team arrangement to six teams.
