BALTIMORE -- New Oriole Joe Saunders flew to Maryland on Monday and is expected to be officially added to the roster on Tuesday.
Right-hander Jake Arrieta, who was recalled from Triple-A Norfolk on Sunday to take the roster spot vacated by Matt Lindstrom, was optioned back to Norfolk following Monday's 4-3 victory over the White Sox. The Orioles' Opening Day starter, Arrieta reiterated that he has worked hard to change his mental focus.
"I don't think there's anybody more frustrated about the way things have gone than I am," said Arrieta, who worked hard to be 100 percent healthy this spring coming off season-ending right elbow surgery and was demoted after pitching to a 6.18 ERA in 18 starts. "Obviously, it's me out there. It's my stats, it's my outings that have affected the team. So, I'm pretty much trying to wipe the slate clean."
While Arrieta's stay was a short one, he is expected to be a September callup. The Orioles' roster will continue to change with the pending returns of Wilson Betemit and Jason Hammel, and the rotation is undecided beyond Chris Tillman starting on Tuesday.
Saunders will start Wednesday or Thursday with Zach Britton "probably" starting the other game, according to manager Buck Showalter. Asked where this leaves rookies Steve Johnson, who has pitched well in both of his starts, and Miguel Gonzalez, who has been arguably the biggest surprise of the season, Showalter said they remain candidates.
"Stevie's presented himself well against Seattle and Toronto," Showalter said. "We'll get Miguel in there at some point, I'm sure."
