BALTIMORE -- Orioles right-hander Chris Tillman was slated to see team orthopedist Dr. John Wilckens on Thursday, with the team waiting for him to be cleared before picking up a ball.
"It's been four days since I've pitched and I think they said they wanted to give me four or five days," said Tillman, who exited Sunday's game with right elbow discomfort that an MRI diagnosed as inflammation. "Right now, it feels fine."
Manager Buck Showalter was equally optimistic about Tillman and said the MRI revealed an elbow ligament that was in surprisingly good shape for a Major League starter. Once Tillman is cleared to play catch, which is expected to be in the next day or two, the team will map out a more detailed plan.
Tillman is not listed among Baltimore's starters for the four-game set with New York that started Thursday and -- while Showalter said he remains an option -- it's more likely he will slot back in following Monday's off-day.
Right-hander Jake Arrieta joined the club on Thursday afternoon and he will be activated on Friday.
Arrieta, who made his final start of the Triple-A season Monday, could be an option for the rotation depending on what happens with Tillman and right-hander Jason Hammel, who was activated off the disabled list Thursday for his first start since July 13.
