Akin was optioned to the Orioles' alternate training site Friday.
Akin had a rough outing in Friday's loss to the Nationals as Baltimore's pitching staff was unable to quiet Washington's bats. The southpaw threw 48 pitches over three innings, 29 of which were strikes. He'll work on improving at the alternate training site, but he could rejoin the major-league bullpen at some point in 2020.
