Rutschman is out of the lineup for Monday's game against the Mariners.
After he had been recently managing an elbow injury, Rutschman started behind the plate in three of the Red Sox's four games against the Yankees over the weekend, going 3-for-12 with two runs during that stretch. Rutschman isn't believed to have suffered a setback with his elbow coming out of the series with New York, so he's presumably just getting a maintenance day Monday.
