This difference is directly represented in the head-to-head match-ups. Now nearing the end of the regular season, the Astros find themselves outside of striking distance for the division. With just 19 games left in the season, they are 9.5 games out of first place. They do still have a chance to make the postseason as a wild card team. The Stros are 3.5 games behind the Toronto Blue Jays and are playing some pretty good baseball.
But the Astros have actually been the better team this season when not playing the Rangers. If they could have played as well against the Rangers as they have against the rest of the teams, they would be winning the division now.
