The Sox are still chasing Tampa for first place. (Never thought I'd write *THAT* sentence)
Barring a huge collapse, which is still possible given the Sox pitching situation (no, I don't trust Bartolo Colon in the rotation), the postseason pairings are predictable. As of today, the Sox are 1.5 games behind the Rays and lead the wild card by 6.5 games over the Twins and 7.5 over the Blue Jays and Yankees.
The Angels will play the wild card team with the winner of the East against the winner of the Central (either the Chisox or the Twins). The Sox want to win the East because the Angels are such a nightmare.
The way things are going, though, the best thing the Sox can do is hope someone else beats up on Tampa (thanks, Minnesota), because they seem to have Boston's number.
