May 31, 2025 12:01 PM : The Orioles recalled Mayo from Triple-A Norfolk on Saturday. He will start at designated hitter and bat sixth Saturday against the White Sox.
Analysis: With Ryan Mountcastle (hamstring) moving to the injured list, Mayo will rejoin the active roster to give Baltimore some additional infield depth. The 23-year-old went just 1-for-12 during his previous stint in the big leagues this season and has slashed .180/.265/.328 across 61 plate appearances since being sent back down to Triple-A.
