5 games back toward the end of July against a team that obviously has your number, at the time being, is not a good spot to be in.
If the Angels win the next two, 3 games back is manageable because the Rangers are likely not going to win 12 or more in a row again.
If the Rangers win the next two, you can crown them AL West champs already. Angels won't come back from 7 games against a team with good pitching and hitting.
...another note, how is Mathis still playing? At this point, I'd take Conger over Mathis any day of the week.
