Detroit's defense is not very good, especially in the outfield.
Granderson is good but the corner outfielders suck, which is part of the explanation for Washburn's regression, he left the best defensive OF in the majors for one of the worst.
As for this thread, I think the Sox should go balls out until Friday. If they are 4 games or less out come Friday, go for the division. Any more, ease off the gas.
