Orioles right-hander Jake Arrieta will have surgery in California on Friday to remove a bone spur from his right elbow. It was the expected course of action, but the decision was made after he had a CT scan and MRI today.
Los Angeles Angels team physician Lewis Yocum will perform the surgery on Friday morning. Arrieta said the time has not been determined.
He will be out for at least two months but hopes to begin his normal throwing program in late November or early December and expects to be ready by the spring.
He finished the season 10-8 with a 5.05 ERA in 22 starts.
