The Boston Red Sox placed left-hander Joely Rodriguez on the 15-day injured list amid a series of bullpen moves on Sunday.
Rodriguez, 31, is dealing with left shoulder inflammation and his designation is retroactive to Thursday.
Rodriguez has no decisions and an 18.00 ERA in five relief appearances in his first season with the Red Sox.
Boston also optioned left-hander Ryan Sherriff to Worcester and recalled right-hander Kaleb Ort and lefty Brennan Bernardino from the Triple-A club.
Sherriff, 33, pitched in both games of Saturday's doubleheader split with the Tampa Bay Rays.
