The Sox are batting a major league best .299 at home this year. They're second in the league for runs scored at home (113), and are probably tops for average runs scored per game at home (a hair under 7). Over the last 7 days they are batting .323 and have scored a league leading 48 runs. Detroit, on the other hand, has scored 105 runs on the road this year (3rd in MLB) and have scored 37 in the past 7 days (4th in MLB), while batting .302. That said, if I end up on a side, it will be the Sox. And I can't help but think the under is not a great value. Same can be said about the over too though.
