Atlanta recalled Waldrep (elbow) from Triple-A Gwinnett on Thursday and placed him on the 60-day injured list.
Waldrep will join the big-league 60-day IL to free up space on the 40-man roster for Elieser Hernandez, who was selected to the 28-man roster Thursday. Waldrep is slated to miss the entire 2027 campaign after undergoing Tommy John surgery on his right elbow.
