Masterson struck out four as the Red Sox stretched their Grapefruit League winning streak to five. In five spring innings, Masterson has yet to surrender a run.
New Red Sox left fielder Hanley Ramirez hit an RBI double.
Jackie Bradley Jr., competing for playing time in the Boston outfield, doubled and singled with a walk.
