Diamondbacks' Shelby Miller to have MRI exam on forearm

Miller has been contemplating Tommy John surgery over the past few days, and now it's official, the 26-year-old will have the surgery.

Diamondbacks starting pitcher Shelby Miller is scheduled to have a precautionary MRI exam Monday after exiting early from Sunday's game against the Dodgers, the team announced.

Miller (2-2) left his team's eventual 6-2 loss in the fifth inning because of right forearm tightness. He held the Dodgers scoreless through four innings but was responsible for three runs in the fifth, in which he didn't retire a batter.

After the game, he downplayed the severity of the problem.

"I feel it will feel better [Monday],'' Miller said, via ESPN. "I don't think it is that big of an issue. Just one of gross things that flares up when you are out there.''

Diamondbacks manager Torey Lovullo acknowledged Miller's slump but praised his performance so far this season and is hopeful the injury won't hold back the five-year veteran for long.

"These are tough things for me to address. It is really unfortunate,'' Lovullo said. "Shelby has been throwing the ball really well. This is a minor setback for him, but, numbers aside, you just hate to have a situation like this pop up.''

Miller, 26, ERA rose to 4.09 after Sunday, though it's still better than the 6.15 ERA he posted in 20 starts last season.
