Cardinals' Keynan Middleton: Seeking second opinion

Middleton (forearm) will get a second opinion from a specialist Monday, John Denton of MLB.com reports.

Middleton underwent an MRI on Friday after being checked out by team doctors and it appears he may be dealing with a significant injury to his throwing arm. Season-ending surgery has yet to be ruled out, though even if he avoids surgery, Middleton could have to start over after being close to returning from the 15-day IL just days before reporting the injury. Regardless, there should be more clarity regarding Middleton's status in the coming days.
