Head to head results, I guess? If that were tied, I don't know what the next move would be - but then, since most inter-division matchups are 6 games per season, if one weren't completed, odds are someone would have the H2H edge. Let’s say the overall NL standings end like this: Cubs - Braves 0.5 GB They wouldn’t make the Cubs makeup the game and the Cubs would be seed #1. But if they looked like this. Dodgers - Cubs 2.5 GB Braves 3 GB (and hold tie breaker) They would make the Cubs play the extra game to determine if the Cubs or Braves would have HFA for LDS.
