Even with the addition of left-hander Donnie Hart to the Orioles' bullpen on Sunday, there's plenty of uncertainty facing the team's pitching staff in the coming week.
After Andrew Cashner starts Tuesday following the scheduled day off Monday, manager Buck Showalter said they'll need a starting pitcher for Wednesday's matinee against the Philadelphia Phillies, with right-hander Kevin Gausman getting an extra day of rest and pitching the series-opener in Boston Thursday.
"We're going to play 20 days in a row after [Monday's off day]," Showalter said.
