Manager Aaron Boone said Sunday that Trivino (elbow) has been shut down due to "shoulder stuff," Bryan Hoch of MLB.com reports.
Trivino had been working his way back from Tommy John surgery and recently agreed to extend his rehab assignment, but it's a moot point now that his shoulder's barking. Boone was vague and didn't disclose the extent of the issue, so it's unclear whether Trivino could still be an option in the postseason.
