The Orioles placed Suarez on the 15-day injured list Monday with right elbow discomfort.
Suarez pitched well in an abbreviated start during Sunday's loss to the Blue Jays, striking out five over three innings of one-run ball. However, he came out of it with a sore pitching elbow, which will sideline him for the remainder of the season. Suarez had previously missed most of the season with a right shoulder strain. He will undergo an MRI on his elbow Monday night to determine the severity of the injury, per Roch Kubatko of MASNSports.com.
