Catcher Ronny Paulino has accepted his assignment and will remain in the organization, forgoing free agency to stay with Triple-A Norfolk and split duties with Luis Exposito. Paulino was outrighted on Saturday to make room for Taylor Teagarden.
Pitcher Dana Eveland cleared waivers and was outrighted to Triple-A Norfolk. Eveland was placed on waivers on Saturday and is expected to be stretched back out to join Norfolk's rotation.
Infielder Nick Johnson tried to hit Monday in extended spring in Sarasota, but experienced some discomfort in his right wrist, so he continues to be out indefinitely. Pitcher Stu Pomeranz -- who had a back issue that kept him from going out on rehab -- resumed throwing on Monday in Sarasota, as he continues to make his way back from an oblique strain.
