It didn't take long for Donnie Hart to realize how things are done in the Orioles bullpen.
Just a few games into his big league career, the team's left-handed specialist took notice that once the fifth inning hit, he was suddenly sitting by himself as his fellow relievers quietly retreated to different parts of the bullpen area to begin their stretching and pregame routines to be ready for a phone call from the dugout at a moment's notice.
"When I got there ... I was left kind of looking around wondering what was going on," Hart said.
