Asher was optioned to Double-A Bowie on Sunday, Roch Kubatko of MASN Sports reports.
Asher is expected to serve in a starting role for Bowie for the duration of its Eastern League playoff run. Once the postseason concludes, Asher should rejoin the Orioles and work in long relief. The big club recalled Gabriel Ynoa from Triple-A Norfolk in a corresponding move to offer additional depth out of the bullpen while Asher is with Bowie.
