Jake Arrieta was scratched from his start Sunday at Triple-A Norfolk with a right shoulder strain.
The Orioles aren't overly concerned about it, but Arrieta will need to be reevaluated before making his next start. Depending on how quickly he recovers, he could be an option for a rotation spot with Wei-Yin Chen (oblique) likely to require a stint on the disabled list. Arrieta has a 2.75 ERA in three starts at the Triple-A level.
