Mountcastle (wrist) reported to Triple-A Norfolk to begin a rehab assignment Friday, Matt Weyrich of The Baltimore Sun reports.

EDGE Analysis

The 27-year-old will get in a few games at Triple-A this weekend before potentially rejoining the Orioles early next week. Mountcastle has been sidelined nearly a month due to a sprained left wrist but should give Baltimore a boost for the final days of the regular season.
