Mateo went 0-for-4 with one RBI, one run scored and two stolen bases in Saturday's loss to the Red Sox.
The Orioles have been running rampant against the Red Sox in the first two games of the series -- they've already picked up 10 steals as a team. Mateo has four of them, as he's swiped two bags in back-to-back games. There's very little offensive upside in the other categories, but Mateo should again be a major contributor with steals because of his impressive speed.
