Nicasio is probably a little upset, the Pirates were maneuvering to get him to an AL contending team and the Phils stepped in and claimed him. He might be a little bummed.
Velasquez is having surgery so I assume his season is over, he could certainly be moved to the 60 day DL.
Odubel and Altherr are going on rehab assignments and will be back soon I assume.
Of all things, Appel pitched an inning in the GCL. He is not a prospect anymore (he never really was, at least not during his time with the Phils) but might still be claimed if moved off the 40 man. All reports are that he is a good guy, but he just isnt a particularly good pitcher (see his records not his draft position).
