Manager Buck Showalter said he has had preliminary discussions with his coaching staff and the Orioles player development staff this week about potential call-ups when rosters expand Sept. 1.
The Orioles' 40-man roster is currently full, so the club would have to clear space to add and promote any nonroster players. But one spot can be created by transferring catcher Matt Wieters to the 60-day disabled list.
"There's obviously some roster issues we have to manage with the 40, but we have a couple guys we haven't even put on the 60-day disabled list yet," Showalter said. "You've got to be at 40 before you put a guy on the 60. If it's the right guy and he serves the right need, the roster shouldn't be an issue. When we're looking at potential call-ups, whether or not they're on the roster or not is not an issue. I think they believe us because we've done it so many times."
Right-handed relief pitcher Ryan Webb undoubtedly will return then, if not sooner, and Showalter is especially excited about the prospect of adding Joe Saunders as a multiple-inning left-handed reliever. Saunders pitched a scoreless one-inning outing Saturday at Norfolk. The winning pitcher in the team's victory over the Texas Rangers in the 2012 wild-card game, he signed a minor league deal with the team Aug. 1.
"We talked with Joe in the offseason about potentially doing that role from the get go, but he wasn't through starting, and rightfully so," Showalter said. "He got an opportunity, and he got compensated well for it. I would have done the same thing."
