Cardinals' Keynan Middleton: Undergoing imaging

Middleton (forearm) is getting imaging done and will be checked out by team doctors Tuesday, John Denton of MLB.com reports.

Middleton reported soreness after making back-to-back rehab appearances at Double-A Springfield and will get evaluated by the team. He's been sidelined since March with a strained right forearm and was close to being activated from the 15-day IL before suffering the setback.
