He's expected to be in uniform Tuesday night against the San Diego Padres.
To make room for Escalona, the team optioned right-hander Tyler Chatwood to the Sky Sox. Chatwood was 1-0 with a save and a 5.63 ERA in four appearances. Manager Jim Tracy said the move was made simply to get Chatwood more time on the mound.
Tracy said he believes that Tyler Chatwood "is going to resurface and do some special things for this club."
The 25-year-old Escalona had two saves for the Sky Sox and didn't allow a run in five innings.
