Entering the last game of the season, the Red Sox outfield is tied for the most DRS by an outfield in the last 10 years. OAA, however, stalled out at 22, well behind the Rays and Cubs outfields.
The Red Sox outfield has the 11th-most defensive runs saved and 17th-most outs above average in a single season. They've done it in about half the innings of everyone else.
