Melancon gave up four runs on four hits over one inning in a rehab appearance at High-A San Jose, broadcaster Joe Ritzo reports.
This rehab appearance was going to be a big one in determining how ready Melancon was to return to the majors. Expect an update later this week but after this rough outing, the Giants may choose to slow Melancon's rehab down to make sure he's fully healthy and ready to contribute down the stretch.
