Shelby Miller Undergoing Testing After Leaving With Elbow Tightness

Diamondbacks righty Shelby Miller departed his outing yesterday after just one inning of work. After the game, as Nick Piecoro of the Arizona Republic reports, Miller left the club to receive a full medical evaluation for what has been labeled as “right elbow tightness.”

Clearly, there’s cause for concern for a pitcher who had only just returned from Tommy John surgery. “You could definitely tell something was wrong,” catcher Alex Avila said of Miller. The team’s immediate decision to send the starter back to Phoenix for review certainly reflects that sentiment.

That’s not to say, of course, that Miller is necessarily dealing with another serious injury. Seemingly ominous situations have resolved favorably plenty of times in the past, so there’s still reason to hope for the best.

Regardless, it’s surely a frustrating time for the 27-year-old Miller. The TJ rehab process, after all, is not a short one. He has generally been hit hard in his four starts this year, but there are promising signs as well. Miller has managed a 19:7 K/BB ratio through 15 innings and is back at his typical mid-nineties velocity.

Miller is earning $4.9MM this year, with one more year of arbitration control remaining. The Snakes have two starters (Matt Koch and Braden Shipley) available on the 40-man roster if it turns out that Miller will need to miss time.
