The Orioles transferred Mateo (hamstring) from the 10-day injured list to the 60-day IL on Sunday.

EDGE Analysis

Initially placed on the IL on June 7 due to left elbow inflammation, Mateo was on the cusp of returning before he suffered a significant left hamstring strain during a rehab game with Triple-A Norfolk last Sunday. The Orioles are expecting him to miss two or more months due to the hamstring injury, so his move to the 60-day IL won't affect his return timeline. The transaction opened up a spot on the 40-man roster for catcher Alex Jackson, acquired from the Yankees on Sunday.
