Christian Montes De Oca will undergo an MRI on his elbow on Tuesday.
Montes De Oca was with Arizona over the weekend but didn’t pitch. He was briefly sent back to Triple-A but then recalled on Monday when Kendall Graveman went on the IL. However, Montes De Oca felt discomfort in his elbow on Monday and was not available to pitch. Diamondbacks manager Torey Lovullo said, “his concern is high.” We’ll have to wait for the MRI results to know more, but the Arizona bullpen is not in good shape right now.
