Baseball Games Back Calculated
August 29th, 2007

How do they calculate how many Games Back a team is from a Division Leader in MLB; how can a team be .5GB?
Major League Baseball
GB == ((difference in wins) + (difference in losses)) / 2
using absolute values for the two differentials (we only care about the size of the separation, not the direction).
Think of it this way: two teams are involved in every game, so the outcome is worth 1/2 game to each team.
It may seem a little weird, but it’s just bookkeeping.
