Stephen Drew drove in 11 runs in 39 games with the Red Sox before they dealt him to the Yankees in the hour before the July 31 non-waiver trade deadline. In seven games since, he has knocked in six runs. His RBI ground-rule double in the fourth was the difference in the Yanks’ 1-0 win over the Tigers at the Stadium on Thursday. Drew lofted the hit down the left field line, where it bounced in fair territory and skipped into the stands, scoring Carlos Beltran from second base.
