Regular season standings
Interleague results
Current as of 25 September 2018
Interleague results are placed in order of current regular season standings. The 'I' column indicates the teams' interleague position.
The interleague results are indicative only of the teams playing ability against those teams in the opposing league, and have no bearing on the placings or Climax Series'. The sponsor, Nippon Life, does hand out awards to players and teams based on their finishing in the Interleague standings, however.
