• Padres pitching prospect Casey Kelly, on a Minor League rehabilitation assignment with Double-A San Antonio, had an MRI last week on his sore right arm. The MRI returned clear, according to general manager Josh Byrnes.

Byrnes indicated that there's no timetable for when Kelly will pitch in a game. Kelly last threw on May 19 when he threw six scoreless innings against Frisco.
