Duffy (shoulder) managed just four pitches in Sunday's rehab outing for Triple-A Omaha before the game was suspended due to weather, MLB.com's Jeffrey Flanagan reports. Duffy put together four innings of one-run ball in his first rehab outing, striking out four and walking just one. Had his second outing gone as planned, it could have potentially shown enough for the Royals to consider activating the left-hander. This won't be the case, however, as Kansas City brass will likely want to see Duffy in at least one more rehab game. The date for this has yet to be determined.
