Johnson leaves O's for birth of first child

ST. PETERSBURG -- The Orioles' already thin bullpen just got a little tighter, as closer Jim Johnson has returned home to Baltimore with his wife as they expect the birth of their first child.

Johnson arrived in St. Petersburg on Monday night and flew right back out very early Tuesday morning, O's manager Dave Trembley said. There's no timetable for Johnson's return.

Danys Baez will assume the closing duties with Johnson away.

"We can't fill his roster spot," Trembley said. "There's no list you can put him on. I don't know when he'll be back."

The Orioles promoted reliever Kam Mickolio from Triple-A Norfolk on Monday night to replace struggling right-hander Matt Albers, who was optioned down, and Trembley said he feels the relief corps is in slightly better shape than it had been. But losing Johnson for any length of time is a blow to a unit already stretched thin.

"It's better than it was last night," Trembley said. "Last night was next to bare bones. Tonight there's some meat on the hook."

The Orioles had to use three relievers in Monday night's 8-5 loss to the Angels after starter David Hernandez went 5 1/3 innings. That came after Sunday's 13-inning loss in which the relief corps had to throw 7 1/3 frames.

Baez, who hasn't pitched since Sunday, is 4-6 with a 4.18 ERA in 42 games this season. He has yet to record a save.
