Showalter, who is meticulous when it comes monitoring the bullpen's workload, said that he wouldn't hesitate to stretch out relievers -- even closer Jim Johnson -- to multiple innings if needed over the next few days.
"There's not a long haul now. Our guys understand there's some different dynamics going on now with 30-something games left," Showalter said. "You are going to see [starters Scott] Feldman and Miguel [Gonzalez] in the bullpen, different areas, until we get to September. I don't think you will necessarily see us call all the 40-man callups on one day, either."
Designated hitter Wilson Betemit, who will continue his rehab on Thursday with Triple-A Norfolk, will be monitored closely over the next few days as the team weighs whether to activate him from the 60-day disabled list or extend his rehab and have him come up as part of roster expansion.
As they did last year, the Orioles will have players continue to work out at the team's spring facility in Sarasota, Fla., in case of an emergency.
