The slow roll of this season's trade deadline couldn't stop one big tide from rolling in, because for only the second time all season we have a unanimous No. 1. After weeks of splitting the vote with the reigning World Series champs in Houston, the Red Sox regained the highest perch in the Power Rankings for the first time since Week 4. That wasn't the only shakeup in the top five, as the Dodgers nudged past the Cubs by the most slender of margins, perhaps a reward for their acquiring stars Manny Machado and Brian Dozier in a middle-infield makeover that might be enough to put away the NL West race.
