On Sept. 12 at Fenway Park, Miley gave up six runs on eight hits in 1 1/3 innings.
But Miley finished strong, stringing together three encouraging starts to end the season. In his penultimate start of the season on Sept. 24 against Arizona, Miley allowed a run on seven hits in 8 2/3 innings, striking out a career-high 11 batters.
In his first game in Spring Training on Sunday, an 8-3 win for Baltimore, Miley allowed one run on two hits in two innings of work, giving up a home run to Pittsburgh Minor League infielder Eric Wood.
Manager Buck Showalter is hopeful Miley will be able to follow up on the end of last season.
"We know he's capable of it, and I know it's something he really wants to do for a lot of reasons," Showalter said.
"The other team is going to tell me how they're doing as they go forward in spring," Showalter said. "First Spring Training he's been through with us.
"Even a veteran pitcher like Miley, first time out. It's been a long time since they've been on the hill facing people [who are] trying to do damage."
Odds and ends
• Left-handed pitcher T.J. McFarland has cleared waivers and has been released from his contract. The Orioles will attempt to sign him to a Minor League contract.
