Ryan Mountcastle has lost his day-to-day status with the Orioles.
The club announced a few minutes before first pitch that Mountcastle was placed on the 10-day injured list retroactive to Saturday with vertigo.
Catcher Mark Kolozsvary had his contract selected from Triple-A Norfolk, and he reported to the club today.
The Orioles designated pitcher Noah Denoyer for assignment to make room on the 40-man roster.
Mountcastle hasn’t played since Tuesday, with the club explaining his absence as an illness. Manager Brandon Hyde said Mountcastle came to the ballpark yesterday to take some swings and was going to be a full participant this afternoon in batting practice.
