For the first time, the Pacific League implemented a type of end-of-season playoff system. After the 108-game regular season, the four teams with the best winning percentages played an extra twelve regular season games to determine the league's champion. After the 108th game, the standings were:
The four qualifying teams were the Nankai Hawks, the Mainichi Orions, the Nishitetsu Lions, and the Daiei Stars. These four teams proceeded to play in a twelve game "round-robin" stage, with three games versus each opponent, in late September and early October. The results of this stage were:
The Mainichi Orions' won ten of the twelve extra games, which put them into a tie for the first place with the Nankai Hawks. Both teams had 75 wins, however the Hawks had one less loss than the Orions because of a game against the Daiei Stars that ended in a tie earlier in the season. Because of the impact the tie had on the pennant race, the Hawks and the Stars played an extra 121st game. The Hawks won the game, giving them sole claim to Pacific League title. After the season, this faux playoff system was scrapped because of criticism that it was unfair to the three non-qualifying teams that had their seasons truncated.
